Professional maintenance of Tektronix DSA8300 digital serial analyzer, its common faults and causes are analyzed as follows
Fault point: Self-test failed
Cause analysis: Hardware components such as the power board, sampling template, CPU board, or central control board are faulty, or the self-test program is abnormal.
Fault: No output or abnormal waveform
Cause analysis: It may be optical module or electrical module failure, signal channel damage, or amplifier, ADC circuit and other abnormalities. In addition, failure of the chip components on the time substrate can also cause such problems.
Fault point: Indicator light but no light spot or scan line
Cause analysis: It may be that the filament is not bright, or the medium and high pressure are not working properly. In addition, the filter capacitor damage may also lead to such failures.
Fault: Scanning baseline is too dark
Cause analysis: The medium voltage and high voltage values do not conform to the values given in the instructions, and the circuit components such as rectifier diodes and mixing capacitors may be damaged.
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!
