5.2.3 RF Generator
The CX100 RF Generator provides users with a signal source with known parameters. The RF Generator can be used to evaluate the receive performance of the Device Under Test (DUT). The CX100's internal modulation generators can be used in conjunction with the RF Generator to output modulated signals.
5.2.3.1 RF Generator Controls and Settings
The following controls and settings are used to configure the characteristics of the generated RF signal:
Table 5-1 RF Generator Controls and Settings
| Control/Setting | Description |
| Port | This menu selects the RF Generator output connector. • The DUplex connector should be selected as the RF output connector when the lowest level of RF Generator output is needed. • The ANT/SWR connector should be selected as the RF output connector to output high power RF signals. |
| NOTE When the ANT/SWR connector is selected as the RF output connector, the system disables the connector's receive capabilities. | |
| Frequency | This field defines the frequency of the RF Generator signal. The RF Generator Frequency should be set to a value appropriate for the test being performed and to the receive frequency range of the DUT. |
| Frequency Offset Field | Frequency Offset is only supported in Duplex Test Mode. The Frequency Offset field defines the amount by which the RF Generator frequency is shifted when the signal is produced. A frequency offset may be applied to an RF signal to reduce possible interference with other transmitters, or to remove phase noise when performing certain types of measurements. The Frequency Offset field is disabled when the Offset soft-key is set to OFF. When the Offset soft-key is set to ON the following occurs: • The Frequency Offset field updates to an editable field. • The Frequency field updates to a ready only field. When a frequency offset value is entered, the RF Generator Frequency field updates to show the RF Generator frequency with the offset applied. |
| Output Level | This field defines the output level of the RF Generator. The RF Generator Output Level field should be set to a value appropriate for the receive capabilities of the DUT. |
| ATTENTION The output level of the RF Generator should not exceed the approved rating for the input port selected on the receiver. | |
| Offset Soft-key | The Offset soft-key is an on/off toggle soft-key that is used to apply an offset value to the generator frequency. See the Frequency Offset Field description for information. |
| Output Soft-key | The Output soft-key turns the RF Generator on and off. |
5.2.3.2 Configuring the RF Generator
The RF Generator should be configured according to the capabilities of the receiver. Refer to the receiver's input ratings to ensure the output level of the RF Generator does not exceed the operational capabilities of the receiver.
Configure RF Generator Parameters
- Open the RF Generator panel.
- Define the RF Generator Frequency.
- Define the RF Generator Level.
Apply an RF Frequency Offset
- Set the Freq Offset soft-key to ON.
- Define the RF Generator Frequency Offset value.
- The RF Generator Frequency field updates to display the frequency with the offset applied (e.g. 3,001.00 MHz).
NOTE
Frequency Offset field is only supported in Duplex Test mode of operation.
To Output the RF Signal
- Change the RF Gen soft-key to ON.
- The CX100 is now generating an RF signal.
5.2.4 Modulation Generator
The CX100 supports two internal modulation generators which utilize the instrument's RF generator to output modulated signals. The modulation generators function independently from one another, making the CX100 capable of supporting the simultaneous output of two different modulation types. For example, Modulation Generator 1 can be configured to output an AM signal, while Modulation Generator 2 can be configured to output an FM signal.
NOTE
The CX100 only supports one modulation generator when Digital is selected as the Modulation Type. When Digital Modulation is selected as the modulation type on one of the modulation generators, the fields and controls on the other modulation generator are disabled.
5.2.4.1 Modulation Generator Controls and Settings
The following controls and settings are used to configure the characteristics of the outgoing modulated signal that is applied to the carrier frequency (RF generator signal).
Table 5-2 Modulation Generator Controls and Settings
| Control/Setting | Description |
| Modulation Type | The (Modulation) Type menu selects the type of modulation to be applied to the generated signal. The parameters that must be configured to produce a modulated signal are based on the type of modulation selected. • None: No parameters • FM: Deviation, Rate, Waveform • AM: Rate, Depth, Waveform • AM USB/LSB: Rate, Waveform • Digital: File Selection |
| AM or FM Rate | AM or FM Rate defines the rate at which the waveform is varied (modulated) when applied to the carrier frequency. |
| AM Depth | AM Depth defines the a percent by which the modulated waveform varies from the carrier amplitude. |
| FM Deviation | FM Deviation defines the frequency by which the modulated waveform varies from the carrier frequency. |
| Waveform | Waveform selects the shape of the modulated waveform that is being applied to the carrier frequency. |
| File Selection | The File Selection field is enabled when Digital modulation type is selected. The field is used to select a pre-recorded digital modulation file which is applied to the carrier frequency. |
| Mod “x” On/Off Soft-key | The Mod 1 and Mod 2 soft-key turns the corresponding modulation generator on and off. Each modulation generator is controlled independently from the other. |
The CX100 supports the use of an external modulation source for some modulation types (i.e., AM, FM). The instrument must be properly configured to receive a valid incoming audio signal in order to use external modulation.
5.2.4.2 Configuring the Modulation Generator
This section provides instructions to configure the CX100 to output a modulated signal.
Configure RF Generator
- Open the RF Generator panel.
- Define the RF Generator Frequency to which the modulated signal will be applied.
- Set the RF Generator Level to the desired value.
Configure Modulation Characteristics
- Open the Modulation Generator 1 panel.
- Select the Modulation Type.
- Configure modulation parameters.
- Turn Mod Gen 1 or Mod Gen 2 soft-key ON.
To Output the RF Signal
- Select the RF Generator panel.
- Turn the RF Gen soft-key to ON.
- The CX100 is now generating a modulated signal.
5.2.4.3 External Modulation Generator Controls and Settings
The following controls and settings are used to configure the characteristics of the external modulated signal that is being received by the CX100:
Table 5-3 External Modulation Controls and Settings
| Control/Setting | Description |
| Modulation Type | The external modulation parameters that must be configured depend on the type of modulation selected. • None: No parameters • AM: Rate (%), Coupling • FM: Deviation (kHz), Coupling |
| Rate (AM) | Defines the rate at which the waveform is varied (modulated) when applied to the carrier frequency. |
| Deviation (FM) | FM Deviation defines the frequency by which the modulated waveform varies from the carrier frequency. |
| Coupling | Coupling selects how any unwanted AC/DC components are filtered from the received signal. AC Coupling AC coupling filters the DC signal component out of a signal that contains both AC and DC components. The DC component of a signal acts as a voltage offset so removing the component may increase the resolution of signal measurements. DC Coupling DC coupling does not filter components from the signal; both AC and DC signal components are therefore present in the signal. DC coupling is typically used when any offset voltage present is <±100 mV or if the DC content of the signal is important. |
| Mod Ext On/Off Soft-key | The Mod Ext soft-key turns the external modulation generator on and off. |
5.2.5 RF Receiver
The RF Receiver controls and settings are used to determine how the instrument processes an incoming signal. In order to obtain accurate test and measurement results, RF Receiver parameters must be set according to the known characteristics of the incoming signal.
The RF Receiver Port, Frequency, Reference Level and External Attenuator parameters apply to all types of incoming signals. There are additional parameters that must be configured depending on the type of modulation that has been applied to the incoming signal. The modulation type that is selected from the RF Receiver Demodulation Type menu enables the parameters applicable to each modulation type.
Input Overload Caution
CAUTION
Do not overload input connectors. Refer to product labeling or product specifications for maximum input ratings.
5.2.5.1 RF Receiver Controls and Settings
The following controls and settings are used to configure the CX100 RF Receiver. The RF Receiver should be configured according to the expected characteristics of the incoming signal.
Table 5-4 RF Receiver Controls and Settings
| Control/Setting | Description |
| Port | The RF Receiver Port menu selects the input connector at which the incoming signal is being received. This setting should be selected according to the properties of the incoming signal and the requirements of the test being performed.ANT/SWRANT/SWR should be selected for performing high sensitivity, low power measurements. When ANT/SWR is selected, the RF Receiver's pre-amplifier is available. See section , “PreAmp On/Off Soft-key”, on page 5-13 for information.DUPLEXDUPLEX should be selected for receiving high power signals.See “Input Overload Caution” on page 5-10.If the test involves a high power incoming signal that exceeds the input ratings of the RF Receiver input connectors, use an external attenuator (see “External Attenuator” description below). |
| Frequency | The RF Receiver Frequency should be set to match the frequency being transmitted by the DUT. |
| External Attenuator | The External Attenuation field makes adjustments in signal processing to account for the use of an attenuator pad or adapter. The External Attenuator field should be set to a value appropriate to the attenuator pad or adapter being used. |
| Reference Level | Reference Level defines the signal level in relation to the RF Input of the incoming signal; the field should be set according to the expected power level of the incoming signal. |
| Demodulation Type | The Demodulation Type selects the type of modulation that has been applied to the incoming signal, providing controls and parameters necessary to separate the data from the carrier signal. The demodulation controls and parameters that are available are determined by the following: • The type of signal that is being demodulated • The type of AF Filter that is selected to process the incoming signal • The selected filter characteristics (when applicable) • The De-Emphasis setting (when applicable) |
| IF Bandwidth (BW) | IF BW menu selects the IF detection bandwidth. Select the IF bandwidth appropriate for the characteristics of the incoming signal. |
| Δ | A lower bandwidth reduces the interference caused by powerful narrow-band transmitters, therefore, select the lowest bandwidth possible to suit the characteristics of the incoming signal. |
| AF Filters | The parameters that are available for configuring AF Filters depends on the type of filter selected. |
| Low PassWhen Low Pass is selected, the Audio Low Pass and De-Emphasis parameters are enabled. | |
| High PassWhen High Pass is selected, the Audio High Pass and De-Emphasis parameters are enabled. | |
| Band PassWhen Band Pass is selected, the Low Pass Corner Frequency, High Pass Corner Frequency, and De-Emphasis parameters are enabled. | |
| PsophometricWhen Psophometric is selected, the Psophometric (Weight) and De-Emphasis parameters are enabled. | |
| Audio Low Pass | A low-pass filter (LPF) passes signals with a frequency lower than a selected cutoff frequency. The Audio Low Pass filter selects the highest frequency that is allowed to pass through the AF filter; frequencies above the selected frequency are cut off. |
| Audio High Pass | A high-pass filter (HPF) passes signals with a frequency higher than a selected cutoff frequency. The Audio High Pass filter selects the lowest frequency that is allowed to pass through the AF filter; frequencies below the selected frequency are cut off. |
| Audio Band Pass | Audio Band Pass enables the low pass and high pass corner frequency fields which allow the user to define a frequency band to allow signals within a certain frequency band to pass, while blocking signals with frequencies on the outside of the band. |
| Low Pass Corner FrequencyThe Low Pass Corner Frequency defines the lower end of the frequency band filter. Any signal that is detected that falls below this frequency is filtered out of the incoming signal. | |
| High Pass Corner FrequencyThe High Pass Corner Frequency defines the upper end of the frequency band filter. Any signal that is detected that is above this frequency is filtered out of the incoming signal. |
Table 5-4 RF Receiver Controls and Settings (Continued)
| Control/Setting | Description | ||
| Psophometric | Psophometric filters are typically used when measuring the residual noise in audio equipment. The Psophometric filter is included in the signal path to emphasize the audible parts of the signal and attenuate signal components that contribute less to perception of loudness. CCITT and C-message (C-MSG) weighting filters are bandpass filters used to measure audio-frequency noise on telephone circuits.C-MSG FilterThe C-MSG is used for voice, audio, and telecommunication applications in the U.S.CCITTThe CCITT filter is used for international telephone circuits.De-Emphasis | Psophometric filters are typically used when measuring the residual noise in audio equipment. The Psophometric filter is included in the signal path to emphasize the audible parts of the signal and attenuate signal components that contribute less to perception of loudness. CCITT and C-message (C-MSG) weighting filters are bandpass filters used to measure audio-frequency noise on telephone circuits.C-MSG FilterThe C-MSG is used for voice, audio, and telecommunication applications in the U.S.CCCITTThe CCITT filter is used for international telephone circuits.The De-Emphasis filter attenuates signal components by the amount by which they have been amplified (PreAmp is turned ON). In some cases, the combined use of the pre-amp and de-emphasis filter may improve signal to noise ratio of an incoming signal.When the Autotune soft-key is pressed, the CX100 sets the RF Receiver Frequency to the strongest signal detected at the active RF Input connector.PreAmp On/Off Soft-key | When the Autotune soft-key is pressed, the CX100 sets the RF Receiver Frequency to the strongest signal detected at the active RF Input connector.The RF Receiver's pre-amplifier is available for use when the RF Receiver Port is set to ANT/SWR. This soft-key determines whether or not the pre-amplifier is included (ON) in the input signal path.The pre-amplifier (PreAmp) is typically used to boost weak incoming signals to eliminate noise and produce a clean signal that is strong enough to be processed. |
5.2.5.2 Configuring the RF Receiver

5.2.6 AF Function Generator
The CX100 contains two audio function (AF) generators that are capable of supporting the simultaneous output of two signals of different frequencies, shape and power.
The Settings soft-key opens a configuration menu that accesses controls and settings that are used to configure the parameters of the generated audio signal. See Table 5-5, "AF Generator Controls and Settings," on page 5-14 for a description of these settings.
5.2.6.1 AF Generator Controls and Settings
The following controls and settings are used to configure the characteristics of the generated audio signal:
Table 5-5 AF Generator Controls and Settings
| Controls/Settings | Description |
| Frequency | This field defines the frequency of the outgoing waveform. Each function generator can be configured to produce a waveform at a different frequency. |
| Level Type | Level Type selects the manner in which the level is calculated and applied to the outgoing signal. VPP Peak to Peak Voltage (VPP) is measured from the top of the waveform to the bottom of the waveform. Vpp is typically used when working with instantaneous voltages. Vrms Root mean squared voltage (Vrms) is a calculation of Vpp that yields the equivalent DC voltage that would deliver the same energy to the load. Vrms is typically used when there is a requirement to calculate average power in an AC circuit. |
| Level | The Level field defines to output level of the signal in either Vpp or Vrms as selected in the Level Type field. |
| Waveform | The Waveform field selects the type of waveform to be generated by the function generator. |
| Encode Type | Encoding is accessed from the Settings soft-key. Encoding Type selects the protocol standard that is used to format that data that is included in the generated signal. Contact VIAVI for information about support for different types of signal encoding. |
| Coupling | Coupling is accessed from the Settings soft-key. Coupling selects how unwanted AC/DC signal components are filtered from the received signal. AC Coupling AC coupling filters the DC signal component out of a signal that contains both AC and DC components. The DC component of a signal acts as a voltage offset so removing the component may increase the resolution of signal measurements. DC Coupling DC coupling does not filter components from the signal; both AC and DC signal components are therefore present in the signal. DC coupling is typically used when any offset voltage present is <±100 mV or if the DC content of the signal is important. |
| Settings Soft-key | The Settings soft-key opens a menu that accesses the following controls and settings (described above): • Encode Type • Coupling |
| AF Gen “x” Soft-key | The AF Gen 1 and AF Gen 2 soft-keys turn the corresponding AF Generator on and off. |

The SINAD Meter displays the ratio Signal + Noise + Distortion divided by the sum of Noise + Distortion, the result of which is displayed in dB.
(Audio) SNR Meter
Signal to Noise (SNR) measurements compare the level of a desired signal to the level of background noise. SNR is defined as the ratio of signal power to the noise power.
AF Counter
The AF Counter measures the number of oscillations present in the received audio signal. The AF Counter is used to perform tasks such as measuring the frequency of a carrier signal or measuring the frequency accuracy of the incoming signal.

5.2.7.6 Digital Demod Measurements
The CX100 contains a Vector Signal Analyzer (VSA) that processes and demodulates digital data, which is then sent to the device's Digital Demod meters. The Digital Demod meters are used to identify any impairments in the digital signal that may have been introduced by the analog parts of the digital transmitter. More common impairments that negatively impact the performance of a digital modulator are timing drift, frequency offset and amplitude imbalance.
The CX100's VSA estimates certain values in relation to the impairments in the received signal. In order to estimate the impairments, the VSA uses a perfect received signal, called a reference signal, and compares the reference signal to the actual received signal, called the measured signal. Figure 5-5 on page 5-24 shows a high level block diagram of the VSA's main components.
Figure 5-5 VSA Block Diagram
5.2.7.6.1 Digital Demod Meters
The Digital meters are available in Duplex Test and Tx Test Mode when the RF Receiver Demodulation Type is set to Digital (see "Demodulation Type" on page 5-11). The CX100 supports the following digital meters:
(Digital) Power
The (Digital) Power meter is used to evaluate the transmit performance of a digital transmitter.
Error Vector Magnitude (EVM)
Error Vector Magnitude (EVM) is a measure of modulation quality and error performance of a wireless communication systems. The is used to evaluate the performance of a digital transmitter or receiver for the evaluation of software-defined radios (SDRs).
Frequency Offset
Frequency Offset is used to evaluate the frequency accuracy of the signal. The meter indicates the difference between the DUT transmitted signal and the defined RF frequency.
5.2.7.6.2 Digital Meter Controls and Settings
The Digital meters support user selectable measurement types which are described in section 5.2.7.3.2, on page 5-19 and upper and lower limits which are described in section 5.2.7.3.1, on page 5-18. The Digital meters also contain the following controls and settings:
Table 5-9 Digital Meter General Settings
| Control/Setting | Description |
| Center Frequency | The Center Frequency field is a read only field that indicates the RF Receiver Frequency setting. This value should be set to the expected frequency of the received signal. See Table 5-4, “RF Receiver Controls and Settings,” on page 5-10 for information. |
| Reference Level | The Reference Level field is a read only field that indicates the RF Receiver Reference Level setting. This value should be set to the expected power level of the transmitter. See Table 5-4, “RF Receiver Controls and Settings,” on page 5-10 for information. |
| Coarse Search Frequency | The Coarse Search Frequency setting determines whether or not the digital receiver searches for the received signal if the signal is not present at the defined Center Frequency. When this is enabled, the coarse frequency estimation block of the VSA computes a rough estimation of the frequency offset of the received signal and searches for the signal within the estimated offset range. |

5.2.7.6.3 Digital Filter Types
The CX100 Digital Demod filters are used to limit bandwidth and reduce inter-symbol interference (ISI). The CX100's digital demodulator produces a measured signal and a reference signal. The measured signal is the signal that results from demodulating the waveform; the reference signal is the signal that results from demodulating a signal that contains no errors.
The Digital Filter should be configured based on how the radio/radio system under test performs filtering. Filtering will be performed at the transmitter, at the receiver, or distributed between the transmitter and the receiver.
Reference Filter
The Reference Filter is the combined response of the transmit and measurement filter. This filter is applied to the reference signal.
Measurement Filter
The Measurement Filter is the shaping filter in the receiver that is applied before demodulation. For some filters, this filter reduces the inter-symbol interference (ISI). For other filters, this filter reduces energy from other signals.
The following settings are available for the digital filters:
Table 5-12 Digital Measurement Filter Settings
| Control/Setting | Description |
| Type | The Digital meters support the following meter types: Reference Filter • No Filter: No filter is included in the receive path. • Raised Cosine: Should be used in systems which perform all the filtering in the transmitter. Measurement Filter • No Filter: No filter is included in the receive path. • Square Root Raised Cosine: Should be used to test systems that perform partial filtering in the transmitter and partially filtering in the receiver. |
| Roll-off Factor | Defines the amount of bandwidth allowed in relation to the selected filter. |
| Filter Length | Defines the length of the measurement or reference filter. |
5.2.7.6.4 Digital Equalizer Filter
The equalizer is a complex linear Finite Impulse Response (FIR) filter that compensates the channel; the number of "taps" is flexible. The FIR filter is estimated by the Channel Estimation block of the VSA (see Figure 5-5 on page 5-24).
The Equalize soft-key is used to include the FIR filter in the receive path. When the Equalizer soft-key is pressed, the UI updates to display another set of soft-keys, referred to as the Equalizer soft-key panel, which control the states of the equalization filter. The contents of the Digital Equalizer soft-key panel change based on the state of the equalizer. For example, Freeze Equalizer and Reset Equalizer are not enabled until the equalizer is ON (in learning state) and when Equalizer Learn is pressed, the soft-key updates to a status key.

Actions available from this state are Learn, Reset or Off. |
| Reset Equalizer Soft-key | When the Reset soft-key is pressed, the following actions occur: • The equalizer filter is set to an impulse response and then goes to the previous state. • The soft key panel reverts to the Digital Demod Measurements soft-key panel. • The status line on the Equalizer soft-key updates to show Equalizer Learning. Actions available from this state are Freeze, Reset or Off. |
| Equalizer Off Soft-key | When set to OFF, the equalizer filter is bypassed. The only action available from the OFF state is Learning; all other soft-keys are disabled until the Equalizer Learn soft-key is selected. |
5.2.7.7 Transmit Measurements
Transmit measurements are used to evaluate the performance of the DUT transmitter. These meters are available in Duplex Test and Tx Test Mode. The CX100 supports the following transmit measurements:
5.2.7.7.1 RF Frequency Error
The RF Frequency Error meter measures the frequency error of the received signal in relation to the defined RF Receiver Frequency; this meter is used to evaluate the accuracy of the DUT transmitter. The CX100's RF Receiver Frequency must be set to the expected transmit frequency of the UUT in order to obtain valid RF Frequency Error measurements.
The RF Frequency Error meter supports user selectable measurement types which are described in section 5.2.7.3.2, on page 5-19 and lower limits which are described in section 5.2.7.3.1, on page 5-18.
5.2.7.7.2 RF Power Meter

5.2.9.4 RF Analyzer Instrument Settings
The Instrument Settings menu accesses the controls and settings that define how the RF Analyzer receives and processes an incoming signal.
Table 5-19 RF Analyzer Instrument Settings
| Control/Setting | Description |
| Port | The Port menu selects the input connector that is used for analyzing incoming signals.ANT/SWR The ANT/SWR connector should be selected to perform over the air testing using an external antenna or when test parameters require maximum input sensitivity. This connector should be used when analyzing low level RF signals.DUPLEX The DUPLEX connector is a combined (Duplexed) connector that provides an RF generator output connection and an RF receiver input connection. This connector should be used when analyzing high power RF signals. |
| Coupling | The Coupling menu accesses settings that define the Resolution Bandwidth (RBW) and acquisition time that the Analyzer uses to filter the signal. Acquisition time is used in combination with the RBW setting to improve frequency resolution. Acquisition time and RBW bandpass filter should be inversely proportional to one another. Making the acquisition time longer, while keeping the sampling rate the same, results in the ability to use a narrower RBW.Resolution Bandwidth (RBW)RBW filters are the bandpass filters in the IF path that determine the RF noise floor and how close two signals can be and still be viewed separately on the analyzer.A narrower RBW setting more clearly displays close signals as separate signals, however, a narrower bandwidth setting results in a longer sweep time.An RBW setting that is too wide causes signals that are close together to appear as one signal.Auto Mode: system sets RBW to a filter appropriate to the characteristics identified in the received signalManual Mode: allows the user to manually define the RBW. |
| Coupling (cont) | Acquisition TimeAcquisition Time field defines the length of time that samples are acquired from the time domain.Auto Mode: system sets Acquisition time to a value appropriate to the characteristics identified in the received signal as well as the RBW setting.Manual Mode: allows the user to manually define acquisition time. |
| Reference Level | The Reference Level field defines the top value on the plot field's vertical scale. Reference Level can be set to any value within the specified range, but should be set to a value above the expected power level of the incoming signal in order to view the full signal waveform. |
| Frequency Mode | Frequency Mode selects the method used to define the span of the analyzer plot field. Parameters update according to the type of mode selected.Full Span Frequency ModeWhen Full Span is selected, the span defaults to the instrument's full frequency range. The UI updates to display the Start and Stop frequencies as read-only data fields. |
| Center/Span Frequency ModeCenter/Span Frequency mode of operation specifies the center frequency value as well as the frequency span setting.When Center/Span is selected, the UI displays a Center Frequency and Span setting. Center/Span mode uses the sweep Center Frequency value and Span setting to define the frequency span. | |
| Start/Stop Frequency ModeStart-Stop frequency mode of operation defines the sweep start and sweep end frequencies of the swept measurement range.When Start/Stop is selected, the UI displays a Start Frequency and Stop Frequency fields. The sweep start and sweep stop frequencies define the frequency span. | |
| Frequency Mode (cont) | |
| Zero Span Frequency Mode In Zero Span mode the Analyzer does not perform a frequency sweep: it detects the power level at the set frequency. The trace shows detected power against time. When operating in Zero-Span mode, marker position is specified in time. | |
| Amplitude | Amplitude settings affect how the plot field's vertical scaling and how the signal appears when displayed on the plot field. Scale The RF Analyzer uses logarithmic scaling to display the signal amplitude on the analyzer vertical axis. Differences in signal amplitudes are compressed because low amplitude signals are amplified and high amplitude are compressed. This allows signal with widely varying amplitudes to be displayed on the same plot. Log scale is used to view both low amplitude and high amplitude frequencies with same clarity. Vertical Scale Selects the dB division between the vertical scaling on the plot field. |
| Detector Type | The RF Analyzer uses detectors in order to accurately map the correct signal power to the correct frequency point on the display. |
5.2.9.5 RF Analyzer Marker Controls

| Control/Setting | Description |
| Port | The AF Analyzer Port menu selects which input port is being used to receive the incoming signal.Audio InAudio In should be selected to analyze an incoming audio signal.DemodDemod should be selected to analyze the demodulated portion of an incoming RF signal |
| Coupling | The Coupling menu accesses settings that define the Resolution Bandwidth (RBW) and acquisition time that the Analyzer uses to filter the signal.Resolution Bandwidth (RBW)RBW filters are the bandpass filters in the IF path that determine the RF Noise floor and how close two signals can be and still be viewed separately on the analyzer.A narrower RBW setting more clearly displays close signals as separate signals, however, a narrower bandwidth setting results in a longer sweep time.An RBW setting that is too wide causes signals that are closed together to appear as one signal.Auto: When Auto is selected, the system sets RBW to a filter appropriate to the characteristics identified in the received signalManual: When Manual is selected, the user can manually define the RBW. |
| Reference Level | The Reference Level field sets the top value on the display graph. The Reference Level can be set to any value within the specified range. The Reference Level of the display must be set so that the RF signal level falls within the display area. |
| Frequency Mode | Frequency Mode selects the method used to define the span of the analyzer plot field. Parameters update according to the type of mode selected.Full Span Frequency ModeWhen Full Span is selected, the span defaults to the instrument's full frequency range. The UI updates to display the start and stop frequencies as read-only data fields. |
| Frequency Mode (cont) | |
| Center/Span Frequency Mode | |
| Center/Span Frequency mode of operation specifies the center frequency value as well as the frequency span setting. | |
| When Center/Span is selected, the UI displays a Center Frequency and Span setting. Center/Span Mode uses the sweep Center Frequency value and span setting to define the frequency span. | |
| The maximum span of the display is 5 MHz, which is equal to the channel width of the instrument's receiver. | |
| Start/Stop Frequency Mode | |
| Start-Stop Frequency mode of operation defines the sweep start and sweep end frequencies of the swept measurement range. | |
| When Start/Stop is selected, the UI displays Start Frequency and Stop Frequency fields. The sweep start and sweep stop frequencies define the frequency span. | |
| Amplitude | Amplitude settings affect how the plot field's vertical scaling and how the signal appears when displayed on the plot field. |
| Scale | |
| The AF Analyzer uses logarithmic scaling to display the signal amplitude on the analyzer vertical axis. Differences in signal amplitudes are compressed because low amplitude signals are amplified and high amplitude are compressed. This allows signal with widely varying amplitudes to be displayed on the same plot. Log scale is used to view both low amplitude and high amplitude frequencies with same clarity. | |
| Vertical Scale | |
| Selects the dB division between the vertical scaling on the plot field. | |
| Detector Type | The AF Analyzer uses detectors to accurately map the correct signal power to the correct frequency point on the display. Future development will support selectable detector types. |

| Coupling | The Coupling menu accesses settings that define the Resolution Bandwidth (RBW) and acquisition time that the Analyzer uses to filter the signal. AC Coupling AC coupling filters the DC signal component out of a signal that contains both AC and DC components. The DC component of a signal acts as a voltage offset so removing the component may increase the resolution of signal measurements. DC Coupling DC coupling does not filter components from the signal; both AC and DC signal components are therefore present in the signal. DC coupling is typically used when any offset voltage present is <±100 mV or if the DC content of the signal is important. |
| Reference Level | The Reference Level field defines the top power level line on the plot field's vertical scale. Power levels can be measured at any point on the trace in conjunction with the Horizontal Time/div setting. |
| Horizontal | The horizontal setting defines the scale and position of the time axis of the display. Unit Unit selects whether the horizontal scale is represented in seconds (s), milliseconds (ms) or microseconds (μs). Time/Div The horizontal scale selects the amount of time represented by each division (Time/Div) on the plot's horizontal axis. |
| Vertical | The vertical scale selects the number of units of measurements per division on the plot's vertical axis. When Audio In is selected as the input port, the unit of measurement is Volts or milliVolts. When Demod is selected as the input port, the units will be as follows based on the RF Received Demodulation Type: • FM or Digital: Hz • AM: % (percent) |

Table 5-28 Spectrum Analyzer Instrument Settings
| Control/Setting1 | Description |
| Port | The Spectrum Analyzer Port menu selects the input connector for analyzing incoming signals.ANT/SWRANT/SWR should be selected to perform over the air testing using an external antenna or when test parameters require maximum input sensitivity. The ANT/SWR connector should be used when analyzing low level RF signals.DUPLEXANT/SWR should be used when analyzing high power RF signals. The DIPLEX connector is a combined (Duplexed) connector that provides an RF Gen output connection and an RF Receiver input connection. |
| Coupling | Resolution Bandwidth (RBW)RBW filters are the bandpass filters in the IF path that determine the RF Noise floor and how close two signals can be and still be viewed separately on the analyzer.A narrower RBW setting more clearly displays close signals as separate signals; a narrower bandwidth setting results in a longer sweep time.An RBW setting that is too wide causes signals that are close together to appear as one signal.Auto: system sets RBW to a filter appropriate to the characteristics identified in the received signalManual: allows the user to manually define the RBW. |
| Video Bandwidth (VBW)The Analyzer includes a low pass filter, called the video filter, in the signal path following the detector. The video filter reduces high frequency noise on the detected signal and allows low level signals to be identified which would otherwise be buried in the noise.The bandwidth of the video filter is called the video bandwidth, or VBW. The VBW defines the high frequency cutoff point of the filter. Any frequencies that are above the VBW value are clipped.VBW helps improve resolution of weak signals in the presence of the noise signal. The narrower the VBW, the less noise there is in the output signal; however, the narrower the bandwidth, the longer the sweep time. | |
| Reference Level | The Reference Level field defines the top value on the plot field's vertical scale. Reference Level can be set to any value within the specified range, but should be set to a value above the expected power level of the incoming signal in order to view the full signal waveform. |
| Frequency Mode | Frequency Mode selects the method used to define the span of the analyzer plot field. Parameters update according to the type of mode selected.Full Span Frequency modeWhen Full Span is selected, the span defaults to the instrument's full frequency range. The UI updates to display the Start and Stop frequencies as read-only data fields. |
| Center/Span Frequency ModeCenter/Span Frequency mode of operation specifies the center frequency value as well as the frequency span setting.When Center/Span is selected, the UI displays a Center Frequency and Span setting. Center/Span Mode uses the sweep Center Frequency value and span setting to define the frequency span. | |
| Control/Setting' | Description |
| Frequency Mode (cont) | |
| Start/Stop Frequency Mode | |
| Start-Stop Frequency mode of operation defines the sweep start and sweep end frequencies of the swept measurement range. | |
| When Start/Stop is selected, the UI displays a Start Frequency and Stop Frequency fields. The start and stop frequencies define the frequency span. | |
| Zero Span Frequency Mode | |
| In Zero Span Mode the Channel Analyzer does not perform a frequency sweep: it detects the power level at the set frequency. The trace shows detected power against time. When operating in Zero-Span Mode, marker position is specified in time. | |
| Amplitude Settings | Amplitude settings affect how the plot field's vertical scaling and how the signal appears when displayed on the plot field. |
| Scale | |
| The Spectrum Analyzer uses logarithmic scaling to display the signal amplitude on the analyzer vertical axis. Differences in signal amplitudes are compressed because low amplitude signals are amplified and high amplitude are compressed. This allows signal with widely varying amplitudes to be displayed on the same plot. Log scale is used to view both low amplitude and high amplitude frequencies with same clarity. | |
| Vertical Scale | |
| Selects the dB division between the vertical scaling on the plot field. | |
| Detector Type | The Spectrum Analyzer uses detectors in order to accurately map the correct signal power to the correct frequency point on the display. The Detector Type selects the type of math that is used to identify specific information in a received signal. The CX100 Spectrum Analyzer provides the following detector selections: |
| Peak | |
| When Peak is selected, the Spectrum Analyzer displays the maximum value of data sampled within the corresponding time interval for each trace point. Peak would typically be used to measure the peak power of a signal. | |
| Control/Settingi | Description |
| Detector Type (cont) | |
| Negative Peak | |
| When Negative Peak is selected, the Spectrum Analyzer displays the minimum value of data sampled within the corresponding time interval for each trace point. Negative Peak could be used to help identify CW and pulsed signals by comparing positive and negative peak values. | |
| Normal | |
| For the Normal detector, if a continuously rising or falling value is detected, the most positive value is returned, otherwise the bucket processor alternates between most positive and most negative peak. | |
| Sample | |
| When Sample is selected, the Spectrum Analyzer displays the power level corresponding to the data point of the corresponding time interval. A sample detector provides a sample for each trace point on the plot field; each trace point represents a single sample evenly spaced across the Span of the frequency domain. | |
| A sample detector is effective for measuring noise-like signals or low power continuous wave (CW) signals that are near the Analyzer's noise floor. | |
| Δ | A sample detector can show an inaccurate reading for the amplitude of a CW signal if the RBW is set too narrow (reading will be too low). |
| RMS | |
| When RMS is selected, the Spectrum Analyzer displays the average power measurement calculated over the specified number of trace points. | |
| RMS detector would typically be used when performing EMI testing. | |
| Δ | NOTE |
| The number of trace points is defined by the Number Points field in the Sweep controls and settings (see below). | |
| Control/Setting1 | Description |
| Sweep | Sweep time defines how quickly trace data is acquired and updated to the display. This setting must be fast enough to provide quick measurement results, but slow enough to allow the power values at each point to be measured. |
| Number Points | |
| This field defines the number of data points that the Spectrum Analyzer gathers during a single measurement sweep. A higher setting results in more accurate measurement; however, a higher number of data points may result in longer acquisition time. | |
| Sweep Type | |
| When set to Auto, the instrument optimizes the Sweep Time based on the characteristics of the incoming signal. | |
| When set to Manual, a sweep time setting can be entered using the Sweep Time field. | |
| Sweep Time | |
| This field is enabled when Sweep Type is set to Manual. The setting allows the user to manually define the sweep time setting. | |
| When Sweep Type is set to Auto; the field displays the system defined sweep time setting. | |
| Sweep Mode | |
| This toggle switch selects whether the analyzer performs signal sweeps continuously, or if the analyzer performs a single sweep before being switched off. | |
| In Single sweep mode, the measurement is stopped after a single signal sweep. | |
| In Continuous mode, the analyzer measures continuously, repeating the signal sweep as long as the analyzer is ON. | |
5.4 VSWR/DTF
5.4.1 Introduction
The VSWR/DTF test function supports Voltage Standing Wave Ratio (VSWR), Return Loss and Distance to Fault (DTF) measurements, providing the tools necessary to analyze, troubleshoot and characterize cable and antenna systems.
A cable database is provided for DTF testing. The cable database contains a list of standardized cables for quick test setup and also allows the user to add cables for customer test requirements.
5.4.2 VSWR/DTF Screen Layout and Behavior
The VSWR/DTF screen uses a tabbed layout which allows for quick selection between available functions. Test function screens are displayed by selecting the tab at the top of the screen, or by swiping the screen left or right. Screen layout contents are described under each test function.
5.4.3 VSWR Test Function
The VSWR test function provides users with the ability to select VSWR or Return Loss modes for calculating reflection (see "Measurement Mode" on page 5-63).
VSWR
Voltage Standing Wave Ratio (VSWR) is a measurement that represents how well an antenna's impedance is matched to the radio or transmission line to which it is connected.
The smaller the VSWR measurement, the better the antenna and transmission line match, and therefore less loss and better signal strength on the transmission line. The minimum VSWR is 1.0, which means no power is being reflected.
Return Loss
Return loss (RL) is the ratio of the reflected signal to the transmitted signal. A low return loss indicates less signal reflection and better signal strength. A high return loss indicates more signal reflection and less signal strength, indicating an issue along the transmission line.
When Return Loss is selected measurements are displayed in dB.

Connect the CX100 and UUT as shown in Figure 6-1, then proceed to the next section.
Figure 6-1 FM Transmitter Test Setup Diagram
6.2.4.2 Configure the CX100 Receiver
In this example, the CX100 RF Receiver uses the following settings:
Table 6-2 FM Transmitter Test - RF Receiver Settings
| Parameter | Setting |
| Rx Port | DUPLEX |
| Rx Frequency | 151.100000 MHz |
| Rx External Attenuator | 0.0 dB |
| Reference level | 37.0 dBm |
| Demodulation Type | FM |
| IF Bandwidth | 12.5 kHz |
| AF Filter | Band-Pass |
| Low-Pass Corner Frequency | 300 Hz |
| High-Pass Corner Frequency | 3 kHz |
| De-Emphasis | 0 μs |
To Configure the CX100 RF Receiver:
- Power on the CX100.
- Launch the RF Instrument application on the CX100.
- Select RF Test.
- Select either Duplex or Tx Test tab.
NOTE
If operating in Duplex Mode, verify RF Generator is turned OFF.
- Open the RF Receiver panel.
- RF Receiver Port: select DUPLEX.
- RF Receiver Frequency: set to 151.1 MHz.
- RF Receiver External Attenuator: set to 0.0 dB.
NOTE
The expected transmit power of the UUT is 5 Watts (37 dBm), which is well below the maximum input power of the CX100 (47 dBm), so no external attenuator is required for this test.
-
RF Receiver Reference Level: set to 37.0 dBm.
-
RF Receiver Demodulation Type: select FM.
- RF Receiver IF Bandwidth: select 12.5 kHz.
NOTE
To Calculate Proper Bandwidth
The UUT Transmitter Bandwidth can be determined with Carson's Rule (Sinusoidal Tone):
$$ 2 \times [ \text {M a x i m u m D e v i a t i o n} + \text {M a x i m u m A u s i o n F r e q u e n c y} ] $$
$$ 2 \mathrm {X} [ 3 \mathrm {k H z} + 3 \mathrm {k H z} ] = 1 2 \mathrm {k H z} $$
The formula above provides the value, which in this example is 12kHz , that is used to determine the proper setting for the CX100 IF Bandwidth. In this example, the closest CX100 IF Bandwidth greater than 12kHz is 12.5kHz IF Bandwidth, therefore, in this example procedure, 12.5kHz is selected for the CX100 RF Receiver IF Bandwidth.
AF Filter Selection
When the UUT is keyed, it generates a 67 Hz squelch tone. To determine the voice modulation level and distortion, the 67 Hz tone must be filtered out so that only the 1 kHz test tone is received by the CX100 when measuring these parameters.
In this example, a Band Pass filter is selected so that frequencies lower than 300Hz will not be received by the CX100 Receiver, and frequencies higher than 3kHz are also blocked so as not to interfere with the 1kHz test tone.
6.2.4.3 Configure the CX100 AF Function Generator
In this example, the CX100 AF Function Generator uses the following settings:
Table 6-3 FM Transmitter Test - AF Function Generator Settings

- Open the RF Receiver panel.
- RF Receiver Port: select DUPLEX.
- RF Receiver Frequency: set to 116.5 MHz.
- RF Receiver Reference Level: set to 37 dBm.
NOTE - Use of External Attenuator
The expected transmit power of the UUT is 50 Watts (47 dBm) which is the maximum input power of the CX100, so an external attenuator is required for this test.
The UUT transmits at 47 dBm through the 10 dB external attenuator, reducing the amplitude received by the CX100 to 37 dBm (5 W), therefore the Reference Level of the CX100 is set to 37 dBm so that the power measurements factor in external attenuation to reflect the actual power generated by the UUT.
- RF Receiver Demodulation Type: select AM.
- RF Receiver IF Bandwidth: select 6.25 kHz.
NOTE - IF Bandwidth Selection
For this test, the UUT will generate AM using a 1 kHz tone, which is a narrow-band signal, so the IF Bandwidth is set to the narrowest setting of 6.25 kHz.
NOTE - AF Filter Selection
The UUT distortion is specified as being measured with a 300Hz to 3kHz band pass filter, so the AF Filter field is set to Band Pass to filter.
