analyzer’s front/rear panel and user interface, explains how to use

the instrument with a measurement example demonstration.

4.1General Inspection

When you receive your new instrument, it is recommended

that you check the instrument following these 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.

2.Check the Accessories

The supplied accessories are described in the "Appendix A:

Enclosure" of this Manual. Please ensure that all the listed

accessories are present and undamaged, if any problems are

found please contact your distributor or our local office.

3.Check the Complete Instrument

If there is any physical damage, operational fault, or

performance issue please contact your distributor or our 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.

4.2 Safety Precaution before Operation

4.2.1 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

4.User Notice

cord.

4.2.2 Allowed Variation Range of Supply Power Parameters

The spectrum analyzer is compatible with 100V~240V, 50Hz-60Hz

AC power, Table 4-1 lists the power requirement to run the

spectrum analyzer.

Table 4-1 Working Power Variation Range

Power Supply Parameter

Compatible Range

Voltage

100 - 240 VAC

Frequency

50 - 60 Hz ±10％

Power

22 W

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.

4.2.3 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.

4.User Notice

WARNING

Make sure the supply power is stable before turning on the

analyzer to protect it from damage. Refer to "First Time to

Power on" section 3.

4.2.4 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.

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.

4.3 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

The above ESD protections measures cannot be used

when working with over 500V!

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:

5.Menu Interpretation

⚫ 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 Man]

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 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

5.Menu Interpretation

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. [CF Step Auto Man] shows the auto or manual

mode to setting the steps. When step is under manual mode,

press [CF Step Auto Man] 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 0), 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.

5.2 【SPAN】

Set the spectrum analyzer to span mode. When press 【SPAN】,

[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.

5.2.1 [Span]

5.Menu Interpretation

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.

5.3 【AMPTD】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

5.Menu Interpretation

includes [Ref Level], [Attenuation Auto Manual], [Scale/Div],

[Scale Type Lin Log], [Ref Offset], [Ref Unit], and [Preamplifier

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:

Ref

− a

+ a

 L

mix

(5-3)

Ref

and

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.

5.Menu Interpretation

⚫ 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 1,2,5 or 10dB 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.

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.

5.Menu Interpretation

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.Menu Interpretation

5.13 【Peak】

Executes peak searching immediately and opens the Peak setting

menu.

Key Points:

⚫ If Max is selected from the Peak Search option, it will search and

mark the maximum on the trace.

⚫

The peak search of Next Peak, Peak Right, Peak Left or peaks

in the peak table must meet the specified parameter condition.

⚫

The spurious signal at the zero frequency caused by LO feed

through is ignored.

5.13.1 [Max Search]

Place a frequency scale at the highest point of the trace and

display the frequency and amplitude of the frequency scale in the

upper right corner of the screen. [Max search] does not change the

activated function.

5.13.2 [Next Peak]

Searches the peak whose amplitude is the closest to that of the

current peak. The peak is then identified with a marker. When this

key is pressed repeatedly, you can quickly find a lower peak.

5.13.3 [Left Peak]

Searches the nearest peak located to the left side of the current

peak and meets the current peak and peak thresholds condition.

The peak is then identified with a marker.

5.13.4 [Right Peak]

Searches the nearest peak located to the right side of the current

peak and meets the current peak and peak thresholds condition.

The peak is then identified with a marker.

5.13.5 [Min Search]

5.Menu Interpretation

Searches the peak with the minimum amplitude on the trace and

identifies it with a marker.

5.13.6 [Mkr→CF]

Used to move the peak point to the center frequency point.

5.13.7 [Cont Max On Off]

Set the peak search form, off by default. On mode will

automatically search for the peak.

5.14 【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.

5.14.1 [Marker 1 2 3 4 5]

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 softkey 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

5.Menu Interpretation

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

5.14.2 [Trace 1 2 3 4 5]

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

traces.

5.14.3 [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.

5.14.4 [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. 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

5.Menu Interpretation

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:

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 point to achieve the

delta measurement.

b) 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.

5.14.5 [Off]

The marker information displayed on the screen and functions

based on the marker will be turned off and won’t show up again.

5.14.6 [All Off]

Turns off all the opened markers and the related functions. The

marker won’t show again.

falls off (N<0) or rises (N>0) N dB separately,

Key points:

⚫ When the measurement starts, the analyzer will search the

two points which are located at both sides of the current point

and are N dB amplitudes smaller or greater than the current

point, and display the frequency difference between the two

points.

⚫ You can use the numeric keys, knob or direction keys to

modify the value of N, 3 at default.

5.16.3 [Marker Noise On Off]

Turn on or off the frequency noise function. The function of marking

noise is applied to the selected cursor, and then the noise Power

Spectral Density at the cursor is read. When turned on, the

average noise level read at the frequency scale is normalized to 1

Hz bandwidth for noise power.

5.16.4 [Freq Count►]

Activate the frequency counter function and display the count

results in the upper right corner of the screen. The counter counts

only the signals that are displayed on the screen. The frequency

count also pops up an additional counter function for the soft menu,

7.1 Troubleshooting

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.

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 it the

power supply voltage range is within the specification.

2) If the power switch has been turned on.

3) If the fan is running, please contact us for service.

2. No signal display

If there is no signal display at any wave band. Please try the

following: 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 us for service.

3. Wrong measurement results or poor signal frequency

precision

If the display contents shakes 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】→[frequency reference

Internal External].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

7.Warranty

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.

7.2 Spectrum Analyzer Repair

When it is difficult to solve your spectrum analyzer’s problem, you

can contact us by phone or fax. When it’s confirmed that the

instrument is damaged and need return to repair, you need to wrap

the spectrum with the original packaging material and the packing

box, follow the steps below to package:

1) Write a detailed description of the malfunction of the spectrum

analyzer, put it in the box together with the spectrum analyzer.

2) Put the instrument in a dustproof / antistatic plastic bag to

reduce possible damage.

3) Place pads in four corners of mother packaging carton, then

put the instrument into the mother carton.

4) Seal the carton with tape and tighten it with nylon tape.

5) Mark the carton with words of "Fragile! Do not touch!

Carefully".

6) Ship by type of precise instruments.

7) Keep all the copies of shipping sheets.

CAUTION

The use of other materials to package the spectrum

analyzer may damage the instrument. Do not use

polystyrene pellets as packaging materials, they can not

adequately fit the instrument, and can be sucked into fan by

the generated electrostatic, causing the spectrum analyzer

damage.
