4.2 Safety Precaution before Operation

4.2.1 Power Supply Requirements

The analyzer allows the use of either an internal lithium battery pack, or AC-DC adapter shipped with the analyzer for its power supply.

The lithium battery is 7.4V, 9100 mAh.

The table below lists the requirement of the AC-DC adapter.

Table 4-1 AC-DC adapter requirement

AC-DC adapter parameter	Compatible range
Input Voltage	100 V - 240 VAC, 50/60 Hz
Output Voltage	12 - 15 VDC
Max. Power	45 W

4.2.2 Electro-static Discharge (ESD) Protection

ESD is an issue often ignored by users. Damage from ESD on the instrument is unlikely to occur immediately but will significantly reduce the reliability of it. Therefore, ESD precautions should be implemented in the work environment, and applied daily.

Generally, there are two steps to manage ESD protection:

1) Conductive table mat to connect hands via wrist bands
2) Conductive ground mat to connect feet via ankle straps

Implement both protection methods will provide a good level of anti-static protection. If used alone, the protection will not be as reliable. To ensure user's safety, anti-static components should offer at least 1MΩ isolation resistance.

WARNING

The above ESD protections measures cannot be used when working with over 500V!

Make good use of anti-static technology to protect components from damage:

1) Quickly ground the internal and external conductor of the coaxial cable before it is connected to the spectrum analyzer.
2) Staff must wear anti-static gloves before touching the connector cord or doing any assemble work.
3) Assure all the instruments are grounded properly to avoid static storage.

4.3 First Time to Power on

Note: Keep the air vents always clear of obstructions for proper

ventilation and cooling of the instrument.

CAUTION

Use only the original AC-DC adapter or originally supplied battery for the power source.

The maximum RF input level of an average continuous power is 30 dBm (or 50 VDC signal input). Avoid connecting a signal into the analyzer that exceeds the maximum level.

1) Press the power switch on the front panel.
2) Self-initialization takes about 30 seconds, after the boot screen the spectrum analyzer will default to the scanning curve.
3) After power on, let the spectrum analyzer warm up for 30 minutes for stabilization to obtain the most accurate results.

Basic measurements include, input signal frequency and amplitude display, marked by a frequency marker.

Follow these five simple steps below to implement input signal measurement.

a) Find the signal frequency at full sweep width;
b) Set the center frequency according to the signal frequency in step 1;
c) Setting span and resolution bandwidth;
d) Activate marker;
e) Adjust amplitude parameter.

For example, to measure a 100 MHz, -10 dBm signal, you must turn on the spectrum analyzer and ensure it is warmed up for 30 minutes to ensure measurement accuracy.

1. Equipment connection

Connect the output terminal of signal generator to the RF Input 50Ω connector on the top of the spectrum analyzer. Set the parameters as follows:

Frequency 100 MHz

Amplitude -10 dBm

2. Setting parameters

1) Press 【Preset】 on the front panel to restore the analyzer to its factory-defined state. The Spectrum analyzer will display the spectrum from 9kHz to the maximum span width. The signal generated will display as a vertical line at 100MHz. Refer to Figure 4-10.

Figure 4-10 Full Span

To clearly observe the signal, reduce the frequency span to 1 MHz and set the center frequency to 100MHz.

2) Setting center frequency

Press FREQ softkey on the bottom, select [Center Freq] on the right submenu. Input "100" and select the unit as MHz on the right softkeys. The number keys can be used to set the exact value, the knob and arrow keys can also be used to set the center frequency.

3) Setting frequency span

—Press 【Span】 softkey, input "1" and press MHz as its unit, or press button reduce to 1 MHz.

—Press BW softkey, set [RBW] to Man, and input "30" and press kHz as its unit, or press ↓ button reduce to 30kHz. —Press【Detector】key, set the detection type to Pos Peak.

Figure 4-11 shows the signal at a higher resolution.

Please note that resolution bandwidth, video bandwidth and frequency span are self-adapted. They adjust to certain values according to frequency span. Sweep time can be self-adapted too.

Figure 4-11 Set frequency span

4) Activate marker

—Press Marker softkey on the bottom, the button is located at the bottom of the screen. Then select [Marker >] softkey on the right screen. And press the softkey to select [Marker_1 2 3 4 5 6 7 8], select Marker 1, the marker is located at horizontal center by default, that is the signal peak point or its neighbor.

—Press Marker softkey on the bottom, the button is located at the bottom of the screen. Then select [Peak >] on the right screen. And select [Max Search]. Frequency and amplitude values are read by the marker and shown on the top right of the display area.

5) Setting amplitude

The reference level will be shown at the top of the display grid. To get a better dynamic range, the real signal peak point should be located at or near the top of display grid (reference level). The reference level is also the maximum value on Y axis. Here the dynamic range is increased by reducing the reference level.

Press AMPTD softkey on the bottom, the button is located at the bottom of the screen, and press the [Ref Level] softkey on the right screen. The reference level can be input at the top left of the display grid. Input "-10" using the numeric keypad and set

the unit to dBm. Also can use step button ↓ or knob to adjust.

The reference level is set at -10 dBm, which is the signal peak value near the top of the grid. The balance between the signal peak value and noise is dynamic range.

Figure 4-12 Set reference level

5. Menu Interpretation

This chapter provides you with the information on the function softkeys and hardkeys of the spectrum analyzer.

Key access: [FREQ] softkey at the bottom of the screen

The frequency range of a channel can be expressed by either of two groups of parameters: Start Frequency and Stop Frequency; or Center Frequency and Span. If any such parameter is changed, the others would be adjusted automatically in order to ensure the coupling relationship among them.

$$ f _ {\text { center }} = \left(f _ {\text { stop }} + f _ {\text { start }}\right) / 2 \tag {5-1} $$

$$ f _ {s p a n} = f _ {s t o p} - f _ {s t a r t} \tag {5-2} $$

f_center, f_stop, f_start and f_span denotes the center frequency, the stop frequency, the start frequency and the span respectively.

5.1.1 [Center Freq]

Sets the center frequency of the sweep. When pressed, the frequency mode is switched to Center Freq and Span in order to enter the desired parameter data.

Key Points:

• The start and stop frequencies vary with the center frequency when the span is constant.
• Changing the center frequency horizontally shifts the current sweep channel and the adjustment is limited by the specified frequency range.
• In Zero Span mode, the start frequency, stop frequency and center frequency are always equal. If one is changed the others are updated to match.
• You can modify this parameter using the numeric keys, knob, or direction keys.

5.1.2 [Start Freq]

Sets the start frequency of the sweep. When pressed, the frequency mode is switched to Start Freq and Stop Freq in order to

enter the desired parameter data.

Key Points:

• The span and center frequency are changed automatically according to the start frequency. The change of the span would have influence on other system parameters. For more details, please refer to "Span".
• In Zero Span mode, the start frequency, stop frequency and center frequency are always equal. If one is changed the others are updated to match.
• You can modify this parameter using the numeric keys, knob, or direction keys.
• If start freq is larger than stop freq when setting, then stop freq will increase automatically to the same value of start freq.

5.1.3 [Stop Freq]

Sets the stop frequency of the sweep. When pressed, the frequency mode is switched to Start Freq and Stop Freq in order to enter the desired parameter data.

Key Points:

• Modifying the stop frequency changes the span and center frequency, and the change of span influences other system parameters, see "Span".
• You can modify this parameter using the numeric keys, knob, or direction keys.
• If stop freq is larger than start freq when setting, then start freq will decrease automatically to the same value of stop freq.

5.1.4 [CF Step Auto Manual]

Sets the step of center frequency. Changing the center frequency in a fixed step continuously switches the channel to be measured.

Key Points:

• The frequency step type could be "Manual" or "Auto". In Auto mode, the CF step is 1/10 of span if it is in Non-zero span mode or if the sweep width is zero, the step automatically defaults to 1Hz; in Manual mode, you can set the step using the numeric, step keys or knob. Then activate 【Center Frequency】, press step, center frequency will change as setting step.
  ● After you set an appropriate frequency step and select center frequency, you can use using up and down direction keys to

switch between measurement channels in a specified step in order to sweep the adjacent channels manually.

- You can modify this parameter using the numeric keys, knob, or direction keys.

Frequency step lends itself to detect the harmonic waves and bandwidths that are beyond the current span.

For example, for order of harmonic of a 300 MHz signal, you can use set both the center frequency and frequency step to 300 MHz, and press the up direction key continuously to increase the center frequency to 600MHz, that is secondary harmonic. Press frequency steps to increase center frequency by 300MHz, which reaches 900MHz. [Frequency Step Auto Manual] shows the auto or manual mode to setting the steps. When step is under manual mode, press [Frequency Step Auto Manual] to return to auto mode.

5.1.5 [Freq Offset]

You can set a frequency offset to displayed frequency value, including freq marker value. This movement won't influence sweep frequency range.

While this function activated (frequency offset isn't 0Hz), you can modify this parameter using the numeric keys, knob or direction keys.

5.1.6 [Freq Ref Int Ext]

Set the reference frequency as internal or external input, this is regarded as whole device reference.

5.1.7 [Scale Type Lin LOG]

Setting the scale type can switch the frequency axis to linear or logarithmic, the default is linear.

Key access: [Span] softkey at the bottom of the screen

Set the spectrum analyzer to span mode. When press 【Span】 softkey, [Span], [Full Span], [Zero Span] and [Last Span] submenu

will be available along the right side of the display. You can modify span using the numeric keys, knob or direction keys. Use numeric key or [Zero Span] to clear span.

5.2.1 [Span]

Sets the frequency range of the sweep. When pressed, the frequency mode is switched to Center Freq/Span.

Key points:

• The start and stop frequencies are changed with the span automatically.
• In manual span mode, the span can be set down to 0 Hz, that is zero span mode. And up to the full span described in "Specification". When it is set to the maximum span, it enters full span mode.
• Modifying the span in non-zero span mode may cause an automatic change in both CF step and RBW if they were in Auto mode, and the change of RBW may influence VBW (in Auto VBW mode).
• In non-zero span mode, variation in the span, RBW or VBW would cause a change in sweep time.
• You can modify this parameter using the numeric keys, knob, or direction keys.

5.2.2 [Full Span]

Sets the spectrum analyzer to center frequency/sweep mode, and span of the analyzer to the maximum.

5.2.3 [Zero Span]

Sets the span of the analyzer to 0 Hz. Both the start and stop frequencies will equal the center frequency and the horizontal axis will denote time. The analyzer here is measuring the time domain characteristics of amplitude, located at the corresponding frequency point. This will help to observe the signal (especially for modulated signal) at time domain.

5.2.4 [Last Span]

Changes the span to the previous span setting.

Key access: [AMPTD] softkey at the bottom of the screen

Sets the amplitude parameters of the analyzer. Through these parameters, signals under measurement can be displayed at an optimal view with minimum error. The amplitude submenu includes [Ref Level], [Attenuation Auto Manual], [Scale/Div], [Scale Type Lin Log], [Ref Offset], [Ref Unit], and [Preamp On Off].

5.3.1 [Ref Level]

Activate reference level function and sets the maximum power or voltage for display window.

Key points:

- This value is affected by a combination of maximum mixing level, input attenuation, and preamplifier. When you adjust it, the input attenuation is adjusted under a constant max mixing level, meeting:

$$ L _ {R e f} - a _ {R F} + a _ {P A} \leq L _ {m i x} \tag {5-3} $$

L_Ref , a_RF , a_PA and L_mix denotes the reference level, the input attenuation, the preamplifier, and the max mixing level, respectively.

- You can modify this parameter using the numeric keys, knob, or direction keys.

Reference level located at the top of axis grid. Measurement near the reference level would gain better accuracy, but input signal amplitude should not exceed the reference level; if it exceeds, the signal will be compressed and distorted, result in wrong measurement. Analyzer's input attenuation is related with reference level, it can self-adjust to avoid signal compression. Minimum reference level is -80dBm at Log scale under 0dB attenuation.

5.3.2 [Attenuation Auto Man]

Sets the front attenuator of the RF input in order to permit big signals

(or small signals) to pass from the mixer with low distortion (or low noise). It only works under internal mixer mode to adjust input attenuator insider analyzer. In Auto mode, input attenuator is related with reference level.

Key points:

• When the preamplifier is On, the input attenuation could be set up to 40 dB. You can adjust the reference level to ensure that the specified parameters meet the requirement.
• Modifying the reference level may cause an automatic change in attenuation value; But the change of attenuation value won't influence reference level.
• You can modify this parameter using the numeric keys, knob, or direction keys.

Attenuator adjustment is to make the maximum signal amplitude pass from mixer less than or equal to -10dBm. E.g. if the reference level is +12dBm, the attenuator value is 22dB, then the input level in mixer is -18dBm (12-22-8=-18), its mainly purpose is to avoid signal compression. Switch [Input Atten Auto Manual] to manual mode, adjust the attenuator manually. The highlight under auto or manual stands for auto coupling and manual coupling. When attenuator is under manual mode, press [Input Atten Auto Manual] will match the attenuator and reference level again.

Note: Maximum input signal amplitude of input attenuator (10dB input attenuation at least) is +30dBm, higher power signal will damage input attenuator or mixer.

5.3.3 [Scale/Div]

Sets the logarithmic units per vertical grid division on the display. Select 1,2,4 or 10dB log amplitude scale. It's 10dB/div by default. Every activated marker is with dBm as unit, difference between two markers is treated as marker difference under dB unit.

Key points:

• By changing the scale, the displayed amplitude range is adjusted.
  ● The amplitude that can be displayed is from reference level minus 10 times the current scale value to the reference level.

- You can modify this parameter using the numeric keys, knob, or direction keys.

5.3.4 [Scale Type Lin Log]

Sets the Scale Type of Y-axis to Lin or Log, the default is Log. It only works under internal mixer mode. In general, select mV as Lin amplitude scale unit. Of course there would be other units for select.

Key points:

- In Log scale type: The Y-axis denotes the logarithmic coordinates, the value shown at top of the grid is the reference level, and the grid size is equal to the scale value. The unit of Y-axis will be automatically switched into the default "dBm" when the scale type is changed from Lin to Log.

- In Lin scale type: The Y-axis denotes the linear coordinates, the value shown at the top of the grid is the reference level and the bottom of the grid shows 0 V. The grid size is 10% of the Reference level and the Scale/Div is invalid. The unit of Y-axis will be automatically switched into the default "mV" when the scale type is changed from Log to Lin.

- Other than as mentioned above, the unit of Y-axis is independent of the Scale Type.

5.3.5 [Ref Offset]

Assigns an offset to the reference level to attempt to compensate for gains or losses generated between the device under measurement and the analyzer.

Key points:

- The changing of this value changes both the readout of the reference level and the amplitude readout of the marker, but will not impact the position of the curve on the screen.

- You can modify this parameter using the numeric keys.

- This offset use dB as absolute unit, will not change with selected scale and unit.

5.3.6 [Ref Unit>]

Sets the unit of the Y-axis to [dBm], [dBμW], [dBpW], [dBmV], [dBμV], [W] or [V].

Key points:

1) [dBm]

Choose decibel equals to 1mW as amplitude unit.

2) [dB W]

Choose decibel equals to 1 W as amplitude unit.

3) [dBpW]

Choose decibel equals to 1pW as amplitude unit.

4) [dBmV]

Choose decibel equals to 1mV as amplitude unit.

5) [dBμV]

Choose decibel equals to 1 W as amplitude unit.

6) [W]

Choose Watts as amplitude unit.

7) [V]

Choose Voltage as amplitude unit.

5.3.7 [Preamplifier On Off]

Sets the status of preamplifier located at the front of the RF signal path. Turning on the preamplifier reduces the displayed average noise level in order to distinguish small signals from the noise when working with small signals.

Key access: [Auto] softkey at the bottom of the screen

Searches for signals automatically throughout the full frequency range, adjusts the frequency and amplitude to their optimum and realizes one-key signal search and auto setting of parameters.

Key points: some parameters such as reference level, scale, and input attenuation may be changed during the auto tune.

Key access: [BW] softkey at the bottom of the screen

Sets the RBW (Resolution Bandwidth) and VBW (Video Bandwidth) parameters of the analyzer. The setting menu includes [RBW Auto Man], [VBW Auto Man], [EMI On Off].

5.5.1 [RBW Auto Man]

Adjust the resolution bandwidth ranging from 1Hz to 1MHz. Use

numeric key, step key or knob to switch resolution bandwidth. The underline under Auto or Manual means Auto mode or Manual mode. Press [RBW Auto Manual] to have Auto underlined. Then the resolution bandwidth is under auto coupling mode.

Key points:

• Reducing the value of RBW will increase the frequency resolution, but may also cause sweeps to take longer (Sweep Time is affected by a combination of RBW and VBW when it is in Auto mode).
• RBW decreases with the span (non-zero span) in Auto RBW mode.

5.5.2 [VBW Auto Man]

Sets the desired video bandwidth in order to remove the band noise. Set the video resolution displays in function area, ranging from 10Hz to 30MHz by sequence step. You can modify this parameter by numeric key, step key or knob. The underline under Auto or Manual means Auto mode or Manual mode. Press [VBW Auto Manual] to have Auto underlined to return auto mode.

Key points:

• Reducing the VBW to smooth the spectrum line and differentiate small signals from the noise. However, this may cause a longer sweep time. (Sweep Time is affected by a combination of RBW and VBW when it is in Auto mode).
• VBW varies with RBW when it is set to Auto.

5.5.3 [EMI On Off]

Pop out the menu for EMI measurement bandwidth.

Key access: [Marker] softkey at the bottom of the screen

【Marker>】，【MarkerFctn>】，【Marker→>】，【Peak>】.

5.6.1【Marker>】 right softkey

Key access:

[Marker] bottom softkey → [Marker >] right softkey

We can easily readout the parameters of the marked point on the trace, such as the amplitude, frequency and sweep time.

Key points:

- The analyzer allows for up to 8 pairs of markers to be displayed simultaneously, but only one pair or one single marker can be active at a time. You can use the numeric keys, knob or direction keys to enter the desired frequency or time when any marker type menu is active, so as to view the readouts of different points on the trace.

5.6.1.1 [Marker 1 2 3 4 5 6 7 8]

Selects one marker, the default is Marker1, and place the marker at the center of the trace. If a delta marker is activated, this softkey changes to the menu under the [Delta] function.

If there is already a marker, this command will not produce any operation. If there are already two markers (e.g. in [Delta] mode), [Marker] changes the active marker to a new single marker.

Frequency and amplitude information can be obtained from the marker (time and amplitude information when the span is set as Zero Span), and these values are displayed in the active function area and in the upper right corner of the screen. You can use the knob, touch screen, or the numeric keys to move the active marker.

The marker reads data from the current active track (this track may be track A or track B). If both tracks are active or both tracks are in static display mode, the marker will read data from track A.

Touchscreen Control: When a marker is active, single-tap in the display area (at any level) to quickly move the marker to the desired frequency.

5.6.1.2 [Trace 1 2 3 4 5]

Key points:

• If no active marker exists currently, a sing frequency marker will be activated automatically at the center frequency of current trace.
• You can use the knob or numeric keys to move the marker. The readouts of the marker will be displayed on the upper right of the screen.
• The readout resolution of the X-axis corresponds to the span and sweep points. For higher resolution, add sweep points or reduce the span.

5.6.1.4 [Delta]

One of the marker types, which is used to measure the delta values of X (Frequency or Time) and Y (Amplitude) between the

Reference point and certain point on the trace. When selected, a pair of markers appears on the trace, which are the Reference Marker and the Delta Marker.

Key points:

• If a single marker already exists, the reference marker will be activated at the position of current marker.
  If no marker is active at the present, the reference marker and delta marker will appear at the center frequency location.
• The location of the Reference Marker is fixed (both in the X-axis and the Y-axis), while the Delta Marker is active. You can use the knob, touch screen, or the numeric keys to move the delta marker.
• The frequency (or time) and amplitude differences between the two markers will show in the active area and in the upper right corner of the display. The displayed amplitude difference is expressed in dB, or is the linear unit in terms of the corresponding scale.
• If [Delta] has been activated, press [Delta] again to move the reference marker to the active delta marker position.
• Two ways to enable a certain point as a reference marker:
  a) Open a Normal marker and locate it onto a point and then switch the marker type into "Delta", creating a new reference, then you can modify the location of the delta marker to achieve the delta measurement.
  b) Open a Delta Marker and place the delta marker onto a point, then press [Delta] again to locate the reference marker to this point, then you can modify the location of the delta point to achieve the delta measurement.

Table 5-1 Detector type comparison

Detector Type	Measurement
Pos Peak	Positive peak detector ensures that no peak signal is missed, which is useful for measuring signals that are very close to the base noise.
Neg Peak	Negative peak detector is used in most cases with the self-test of the spectrum analyzer and is rarely used in the measurement. It is able to restore the modulation envelope of the AM signal well.
Normal	Display pos peak and neg peak alternately when noise is detected, or it only display pos peak.
Sample	Sampling detector is conducive to measurement noise signal. Compared with the standard detection method, it can measure noise better.
RMS Avg	RMS Average detector averages rms levels to calculate the true average power. It is best for measuring the power of complex signals.
Voltage Avg	Voltage Average detector averages the linear voltage data of the envelope signal measured during the bucket interval. It is useful for observing rise and fall behavior of AM or pulse-modulated signals.
Quasi-Peak	Quasi-peak detector is a weighted form of peak detection. The measured value drops as the repetition rate of the measured signal decreases. It is used in EMI testing.

7. Troubleshooting

Typical issues that may occur when using your spectrum analyzer:

■ Power on malfunction
■ No signal displays
■ Wrong measurement results or poor frequency or amplitude precision.

1. Power on malfunction

Power on malfunction can include a situation where the screen is still dark (no display) after switch on.

If the screen is still dark after power on, please check:

1) If the power supply has been connected correctly and if the power supply voltage range is within the specification.
2) If the power switch has been turned on.

2. No signal displays

If there is no signal display at any wave band. Please try the following: set a signal generator at 30 MHz frequency and -10 dBm power and connect it to the spectrum analyzer RF input connector. If there is still no signal display, there may be a problem with the spectrum analyzer hardware circuit. Please contact us for service.

3. Wrong measurement results or poor signal frequency precision

If the display contents shake a lot or the frequency readout exceeds the error range during measurements, check if the signal source is stable. If so, check if spectrum analyzer reference is precise. Select internal or external frequency reference according to measurement conditions: press FREQ bottom softkey → [Freq Ref Int Ext]. If the frequency is still not precise, then the spectrum analyzer LO has lost its phase lock, please contact us for service.

4. Wrong measurement results or poor readout amplitude precision

If signal amplitude readout is not precise, perform a calibration. If amplitude readout is still not precise, then it may be a problem with internal circuit, please contact us for service.
