Hao Chen team professional maintenance, quality assurance!!
Professional maintenance of Agilent 35670A signal analyzer, its common faults and causes are analyzed as follows
Fault point: Agilent 35670A signal analyzer black screen
Cause analysis: The component or module of the instrument control board is damaged, resulting in abnormal startup and no display output.
Fault point: The channel cannot be used or the signal attenuation is large
Cause analysis: There are faults in the instrument channel, such as amplitude aberration, analog unit damage, etc., resulting in the normal use of the channel or excessive signal attenuation.
Fault point: Self-test error or calibration failure
Cause analysis: There is a fault inside the instrument, such as the channel plate, signal processing board or main control board is damaged, resulting in self-test or calibration can not pass.
Fault point: abnormal waveform (such as no waveform, waveform distortion, etc.)
Cause analysis: Signal processing circuit failure, or improper instrument Settings (such as filter Settings, sampling rates, etc.), resulting in abnormal waveform display.
By understanding the common faults of the equipment, you can better maintain and use it to ensure its long-term stable operation. If you can not solve, welcome to contact Hao Chen!
