Common faults in network analyzer maintenance | network analyzer maintenance

I believe that engineers are not unfamiliar with network analyzers. Have you encountered network analyzer failures in daily use?Agitek service shares common faults in network analyzer maintenance.

1. power failure

When the network analyzer is repaired, the power failure usually manifests as: the power indicator on the front panel does not light up, the fan does not rotate, the instrument cannot be started normally, or the power supply voltage is unstable, which causes the spectrum analyzer to keep resetting, and the signal power is low due to low analog voltage.

2. Display failure

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. Local oscillator failure

LO faults are usually manifested as: LO loss of lock, large signal insertion loss caused by low LO power, and poor LO spectral purity.

4. Signal path failure

When the network analyzer is repaired, the signal path faults usually manifest 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 failure

When the network analyzer is repaired, the processor failure is usually manifested as: processor hardware and program failure. Due to the high reliability of the processor hardware, in most cases, the processor failure is a program (software) failure.
