5.2.4 Modulation Generator

22144015 August 2023

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

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

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).

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 The Mod Ext soft-key turns the external modulation generator Soft-key on and off. 22144015 CX100 ComXpert Operation Manual Rev 002

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.

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/SWR ANT/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.

DUPLEX DUPLEX should be selected for receiving high power signals.

See “Input Overload Caution” on page 5-10.

PA 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).

D The RF Receiver Frequency should be set to match the frequency being transmitted by the DUT.

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 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.

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 BW menu selects the IF detection bandwidth. Select the IF

PreAmp On/Off Soft-key

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.

The C-MSG is used for voice, audio, and telecommunication applications in the U.S.

CCITT The 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.

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.

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.

5.2.7.6.3 Digital Filter Types

The CX100 Digital Demod filters are used to limit bandwidth and reduce inter-symbol interference (IS). 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.

CX100 ComXpert Operation Manual 22144015 August 2023

Chapter 5 RF Instrument Function Descriptions RF Test

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.

The Reference Filter is the combined response of the transmit and measurement filter. This filter is applied to the reference signal.

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.

The RF Analyzer is used to evaluate the receive performance of the device under test (DUT). The RF Analyzer is an asynchronous, swept analyzer that displays the spectrum of the RF signal received by the test set over a 5 MHz bandwidth. The source of the signal is from the DUT, and the signal is routed through the test set's receiver chain, therefore the RF Analyzer is dependent on the receiver for receive settings such as connector selection, attenuation and center frequency.

NOTE The RF Analyzer is not available when the RF Receiver Demodulation Type is set to receive digital signals (see "Demodulation Type" on page 5-11).

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 signal

Manual Mode: allows the user to manually define the RBW.

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.

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.

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.

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.

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.

DUPLEX DUPLEX should be used when analyzing high power RF signals. The DUPLEX connector is a combined (Duplexed) connector that provides an RF Gen output connection and an RF Receiver input connection.

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 signal

Manual: allows the user to manually define the RBW.

Table 5-28 Spectrum Analyzer Instrument Settings (Continued)

Control/Setting‘ Description

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 mode

When Full Span is selected, the span defaults to the instrument's full frequency range. The Ul updates to display the Start and Stop frequencies as read-only data fields.

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 Ul displays a Center Frequency and Span setting. Center/Span Mode uses the sweep Center Frequency value and span setting to define the frequency span.

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 Ul 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 Amplitude settings affect how the plot field’s vertical scaling and Settings 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.

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:

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.

Table 5-28 Spectrum Analyzer Instrument Settings (Continued)

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.

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.

When Sample is selected, the Spectrum Analyzer displays the power level corresponding to the data point of the corresponding time interval. À 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.

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).

NOTE 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.

The number of trace points is defined by the Number Points field in the Sweep controls and settings (see below).

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.

This field defines the number of data points that the Spectrum Analyzer gathers during a single measurement sweep. À higher setting results in more accurate measurement, however, a higher number of data points may result in longer acquisition time.

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.

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.

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.

Chapter 5 RF Instrument Function Descriptions VSWR/DTF

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 VSWRIDTF 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 (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.

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 ous

To Configure the CX100 RF Receiver:

1. Power on the CX100.

2. Launchthe RF Instrument application on the CX100. 3. Select RF Test.

4. 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

9. RF Receiver Reference Level: set to 37.0 dBm.

CX100 ComXpert Operation Manual

Chapter 6 Performing Tests and Measurements

10. RF Receiver Demodulation Type: select FM. 11. 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 X [Maximum Deviation + Maximum Audio Frequency]

2 X[3 kHz + 3 kHz] = 12 kHz The formula above provides the value, which in this example is 12 KHz, that is used to determine the proper setting for the CX100 IF Bandwidth. In this example, the closest

CX100 IF Bandwidth greater than 12 kHz is 12.5 KHz IF Bandwidth, therefore, in this example procedure, 12.5 kHz is selected for the CX100 RF Receiver IF Bandwidth.

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 300 Hz Will not be received by the CX100 Receiver, and frequencies higher than 3 kHz are also blocked so as not to interfere with the 1 kHz test tone.

6. RF Receiver Port: select DUPLEX.

7. _RF Receiver Frequency: set to 116.5 MHz. 8.

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.

9. RF Receiver Demodulation Type: select AM.

10. 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 300 Hz to 3 KHz band pass filter, so the AF Filter field is set to Band Pass to filter.
