How to analyze the failure of the network analyzer? Network Analyzer Repair

Time：2021-11-04                2012

A network analyzer is a comprehensive microwave measurement instrument that can perform sweep measurements in a wide frequency band to determine network parameters. It can measure S-parameters, Polar plots, Smith charts, etc. It is widely used in the RF field. With the increase in the usage rate of network analyzers, the instrument will inevitably fail. So, how to judge the failure of the network points, today's Xi'an Agitek network analyzer maintenance engineer will share with you.

Common fault maintenance during network analyzer maintenance:

1. Power failure;

2. Display failure;

3. Local oscillator failure;

4. Signal path failure;

5. Faults such as processor failure can be quickly repaired.

So what does the above failure look like? How to judge? Please listen to the tips of the editor of Xi'an Agitek Network Analyzer Repair Center!
1. Power failure is usually manifested as: the power indicator on the front panel does not light up, the fan does not rotate, the network analyzer cannot be started normally, or the power supply voltage is unstable, which causes the network analyzer to reset continuously, and the signal power caused by the low analog voltage is low, etc. .
2. Display failures usually manifest as: no display (black screen), blurry screen, and gray-white display. Display failure may be caused by the failure of the display itself, the failure of the graphics processing board or the failure of the CPU.
3. The local oscillator failure is usually manifested as: the local oscillator loses lock, the signal insertion loss caused by the low local oscillator power is large, and the local oscillator spectral purity is poor.
4. Signal path faults are usually manifested as: input connector faults, signal cable faults, attenuator faults, preselector faults, inverter faults, intermediate frequency amplification/filtering faults, data acquisition and processing faults.
5. Processor failures usually manifest as: processor hardware and program failures. Due to the high reliability of processor hardware, processor failures are program (software) failures in most cases.
The above is the fault judgment method of the network analyzer introduced by the editor of Xi'an Agitek Network Analyzer Repair Center. I hope that you can judge the fault of the network analyzer in a targeted manner when using it, and then you can prescribe the right medicine! If you are sure that your network analyzer has the above faults, it is recommended not to disassemble the machine without permission, and find the original factory or a professional maintenance organization for inspection and maintenance, so as to avoid the instrument cannot be repaired due to your unauthorized disassembly. After all, the price of a network analyzer is not It's cheap!

Xi'an Agitek Maintenance Center specializes in the maintenance and technical support of various test and measurement instruments and test systems. It is good at network analyzer maintenance, oscilloscope maintenance, spectrum analyzer maintenance, etc. The professional maintenance network is divided into the following faults:
1. Can't boot normally
2. The port does not respond normally; no output; no input; abnormal signal
3. Abnormal test results; calibration failure; out of tolerance
4. garbled; black screen
5. The button has no response; the adjustment knob has no response
6. Do not recognize the storage medium; cannot connect with the control system
7. Other faults, etc.
If your network analyzer has the above failures, please consult Agitek Service.
