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
If signal amplitude readout is not precise, perform a calibration. If amplitude readout is still not precise, then it may be a prob
-
lem 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.
