Professional maintenance for Aili MT1810A serial bit error rate analyzer + MU181020A expansion module + MU181040A ED module. The common faults and their causes are as follows:
Fault point: Abnormal bit error rate measurement (such as zero bit error rate or sudden value change)
Cause analysis: Poor contact at the signal input port, mismatch in communication protocol between the expansion module and the host, failure of the internal clock synchronization module, excessive signal attenuation leading to detection failure.
Fault point: Module cannot be recognized
Cause analysis: Oxidation or wear of the interface gold fingers of the module, failure of the host module recognition circuit, incompatibility of the firmware version of the expansion module with the host, open circuit in the module power supply line.
Fault point: Failure of data storage in the ED module
Cause analysis: Damaged storage chip of the ED module, aging of data writing circuit components, incorrect setting of the storage path, failure of the data transmission bus between the host and the ED module.
Fault point: No response after device startup
Cause analysis: Damaged main power switch, abnormal output voltage of the internal power module, bulging and leakage of the motherboard capacitor, overload of the expansion module causing the protection circuit to activate.
