USER NOTICE

This chapter helps you in preparing the spectrum analyzer for use and provides the information to start using the spectrum analyzer correctly.

General Inspection

When you receive your new instrument, it is recommended that you check the instrument following these steps:

Steps

1. Check for transportation damage.

If it is found that the packaging carton or the foamed plastic protection cushion has suffered serious damage, do not throw it away until the complete device and its accessories have been electrically and mechanically checked.

1. Check the Accessories

Please ensure that all the listed accessories are present and undamaged, if any problems are found please contact your distributor.

1. Check the Complete Instrument

If there is any physical damage, operational fault, or performance issue please contact your distributor or GW Instek's local office. If there is any damage to the instrument please ensure you keep the original packaging. Ideally you should always keep the original packaging if the instrument must be returned for repair.

Safety Precaution before Operation

Check Power Supply

The analyzer is equipped with a three-wire power cord in accordance with international safety standards. The product must be grounded properly before being powered on, as floating or improper ground may cause damage to the instrument or personal injury.

Make sure the grounding conductor of the spectrum analyzer is grounded before turning on the instrument. After which the AC power cord can be connected. Do not use a non-ground power cord.

Allowed Variation Range of Supply Power Parameters

The spectrum analyzer is compatible with 100V\~240V, 50Hz-60Hz AC power. The table below lists the power requirement to run the spectrum analyzer.

Power Supply Parameter	Compatible Range
Voltage	100 - 240 VAC
Frequency	50 - 60 Hz ±10%
Power	28W

To prevent or lower the risk of damage to the spectrum analyzer from power interference between instruments, especially from peak pulses produced by large power consumption instruments, a 220V/110V AC regulated power supply is recommended.

Power Cord Selection

The analyzer is equipped with a three-wire power cord in accordance with international safety standards. This cable grounds the analyzer cabinet when connected to an appropriate power line outlet. The cable must be rated greater than 250Vac and 2A.

WARNING

Improper grounding may cause damage to the instrument, or result in personal injury. Make sure the grounding conductor of the spectrum analyzer is grounded before turning on the instrument.

Always use a well-grounded power source. Do not use an external power cable, power cord or an auto transformer without grounded protection. If this product is to be powered via an external auto transformer for voltage reduction, ensure that its common terminal is connected to a neutral (earthed pole) of the power supply.

Make sure the supply power is stable before turning on the analyzer to protect it from damage. Refer to "First Time to Power on" on page 14

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 mats 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 with 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.

First Time to Power on

Connect the three-pin AC power cord into the instrument. Insert the plug into a power socket provided with a protective ground.

WARNING

Check the power source before turning on the spectrum analyzer, to protect the device from damage.

Steps

1. Press the power switch on the bottom left of 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 60 minutes for stabilization to obtain the most accurate results.

Build-in Help

The built-in help provides information that refers to every function key and menu key on the front panel. Users can view this help information if required.

Basic Measurement

Basic measurements include, input signal frequency and amplitude display, marked by a frequency marker. Follow these four simple steps below to implement input signal measurement.

Steps

1. Setting center frequency
2. Setting span and resolution bandwidth
3. Activate marker
4. Setting amplitude

For example, to measure a 100MHz -20dBm signal, you must turn on the spectrum analyzer and ensure it is warmed up for 60 minutes to ensure measurement accuracy.

Equipment connection

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

Frequency 100 MHz

Amplitude -20 dBm

Setting parameters

1. Press the Preset button 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.

Preset

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

1. Setting Center Frequency Press the Frequency button and select Center frequency on corresponding pop up menu. Input "100" and select the unit as MHz on the numeric keypad. The keys can be used to set the exact value but the knob and directional keys can also be used to set the center frequency.

1. Setting Frequency Span Press the Span button, input "1" and select MHz as its unit using the + numeric keypad or press ↓ button to decrease to 1MHz.

1. Press the BW button and set resolution bandwidth to manual. Input 30 and select kHz as its unit using the numeric keypad or press ↓ button to decrease to 30kHz.

+

1. Press the Detector button and set the detection type to positive peak.

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.

Activate Marker

1. Press the Marker button in the function area. Press the soft key to select Marker 1 2 3 4 5 6 7 8. Select Marker 1 and the marker is located at horizontal center by default. That is the signal peak point or its neighbor.

1. Press Peak Search button. Frequency and amplitude values are read by the marker and shown on the top right of the display area.

Setting amplitude

1. 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 we reduce to 20dB reference level to increase the dynamic range.

1. Press the Amplitude button. The amplitude setting menu will pop up and the reference level soft key will be activated. The reference level can be input at the top left of the display grid. Input -20 using the numeric keypad and set the unit to dBm. You can also use the ↓ key or the knob for adjustment.

The reference level is set at -20dBm, which is the signal peak value near the top of the grid. The balance between the signal peak value and noise is dynamic range.

Frequency

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

$$ f _ {c e n t e r} = \left(f _ {s t o p} + f _ {s t a r t}\right) / 2 $$

$$ f _ {s p a n} = f _ {s t o p} - f _ {s t a r t} $$

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

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.

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.

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.

Freq Step Auto Manual

Sets the step of center/start/stop frequency. Changing the frequency range 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 equals 25% of RBW while in Zero span mode; 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.

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 0), you can modify this parameter using the numeric keys, knob or direction keys.

Freq Ref Internal External

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

Scale Type LIN LOG

This function can switch the display unit of the frequency axis to linear or logarithmic mode. (Enabled after installing EMI Option)

Span

Set the spectrum analyzer to span mode. When press the SPAN button, Span, Full Span, Zero Span and Last Span will be available to configure. You can modify span using the numeric keys, knob or direction keys. Use numeric key or Zero Span to clear span.

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.

Full Span

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

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.

Last Span

Changes the span to the previous span setting.

Amplitude

Sets the amplitude parameters of the analyzer. Through these parameters, signals under measurement can be displayed at an optimal view with minimum error. The pop out amplitude menu includes Ref Level, Attenuation, Scale/Div, Scale Type, Ref Offset, Ref Unit and Preamplifier.

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:

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

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.

Attenuation

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 Attenuation 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 Attenuation Auto Manual will match the attenuator and reference level again.

Maximum input signal amplitude of input attenuator (10dB input attenuation at least) is +27dBm, higher power signal will damage input attenuator or mixer.

Scale/Div

Sets the logarithmic units per vertical grid division on the display. Select 0.01 \~ 100dB log amplitude scale. It's 10dB/div by default. Every activated marker is with dB 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.

Scale Type

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 “V” 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.

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.

Ref Unit▶

Sets the unit of the Y-axis to dBm, dBmV, dBuV, V or W.

dBm	Choose decibel equals to 1mW as amplitude unit.
dBμW	Choose decibel equals to 1μW as amplitude unit.
dBpW	Choose decibel equals to 1pW as amplitude unit.
dBmV	Choose decibel equals to 1mV as amplitude unit.
dBμV	Choose decibel equals to 1μW as amplitude unit.
W	Choose Watts as amplitude unit.
V	Choose Voltage as amplitude unit.

Preamplifier

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.

Autoset

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.

- Some parameters such as reference level, scale, and input attenuation may be changed during the auto tune. If there is no signal is found, a message “Auto tune fail, can’t search any signal.” will appear on the screen.

Bandwidth

BW

Sets the RBW (Resolution Bandwidth) and VBW (Video Bandwidth) parameters of the analyzer. Pop out the setting menu includes RBW, VBW, and EMI Filter▶.

RBW

Adjust the resolution bandwidth ranging from 1Hz-1MHz. Use numeric key, step key or knob to switch resolution bandwidth. The underline under Auto or Manual means Auto mode or Manual mode.

Key Points

• Reducing the value of RBW will increase the frequency resolution, but may also cause sweeps to take longer (Sweep Time is effected 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.

VBW

Sets the desired video bandwidth in order to remove the band noise. Set the video resolution displays in function area, ranging from 10Hz to 1MHz 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] and hold it in manual until the underline highlighted under Auto to return auto mode.

Key Points

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

Marker

The marker appears as a rhombic sign (shown below) for identifying the point on the trace. 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 three groups of markers to be displayed at one time, but only one pair or one single marker is active every 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.

Marker 1 2 3 4 5 6 7 8

Selects one marker, the default is Marker1. And place the frequency scale at the center of the trace. If the frequency difference is activated, this soft key changes to the menu under the Difference function.

If there is already a marker, this command will not produce any operation. If there are already two markers (e.g. in Difference mode), Marker changes the active frequency scale to a new single frequency scale. Amplitude and frequency information can be obtained from the frequency scale (time information when the sweep width is 0Hz), and these values are displayed in the upper right corner of the active function area and the screen. You can use the numeric keys, the step key, or the knob to move the active frequency scale.

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 frequency scale will read data from track A.

Trace 1 2 3 4 5

In the trace measurement, the frequency scale used to activate the traces.

Normal

One of the marker types, which is used to measure the values of X (Frequency or Time) or Y (Amplitude) at certain point of the trace. When selected, a marker will appear with its own digital ID such as "1" on the trace.

Key Points

• If no active marker exists currently, a one will be enabled automatically at the center frequency of current trace.
• You can use the knob, direction keys 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.

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. Will be in the active area and the display area of the upper right corner, showing the amplitude delta value between the two markers and frequency difference. If a single marker already exists, [Delta] will place a static marker and an active marker to the original position and a single marker position. Use the knob, step key, or number keys to move the marker. If there are two markers, press [Delta] directly. However, if [Delta] has been

activated, press Delta to place the still frequency scale to the active marker. The displayed amplitude difference is expressed in dB, or is the linear unit in terms of the corresponding scale.

Key Points

• The Reference Marker will be activated at the position of current marker, or else both the reference marker and Delta Marker will be simultaneously activated at the center frequency location if no marker is active at the present.
• The location of the Reference Marker is always fixed (both in the X-axis and the Y-axis), while the Delta Marker is active. You can use the numeric keys, knob or direction keys to change the location of Delta Marker.
• The delta of both the Frequency/Time and the amplitude between the two markers are displayed at the upper right of the screen.

Two ways to enable a certain point as the reference:

Key Points

• 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 point to achieve the delta measurement.
• Open a Delta Marker and place it onto a point, then reselect the Delta menu to locate the marker you opened onto this points, then you can modify the location of the delta point to achieve the delta measurement.

Typical issues that may occur when using your spectrum analyzer:

• Power on malfunction.
- No signal display
- Wrong measurement results or poor frequency or amplitude precision.

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

Q1. If the screen is still dark after power on.

please check

• Power on malfunction. If the power supply has been connected correctly and it the power supply voltage range is within the specification.
• If the power switch has been turned on.
• If the fan is running, please contact us for service.

Q2. There is no signal display at any wave band.

A2. Set a signal generator at 30 MHz frequency and -20 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 GW Instek for service.
Q3. The signal amplitude readout is not precise.
A3. Perform a calibration. If amplitude readout is still not precise, then it may be a problem with internal circuit, please contact GW Instek for service.

Q4 The frequency readout exceed the error range during measurements.

A4. 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 the FREQ button [frequency reference Internal External]. If the frequency is still not precise, then the spectrum analyzer LO has lost its phase lock, please contact GW Instek for service.
