Haochen Team Professional Repair, Quality Assurance!!! We professionally repair Anritsu MP1590B Network Performance Analyzer. Its common failures and cause analysis are as follows:
Failure Point: The instrument fails to power on or shows no display
Cause Analysis: The main power switch on the rear panel is not turned on, or the front Power switch has poor contact; power module failure or abnormal power cable connection; the internal motherboard or system software fails to boot due to sudden power loss or hard disk damage.
Failure Point: No laser output from the optical interface
Cause Analysis: The attached safety "Key" and "Remote Interlock" devices for the optical port switch are not installed or not correctly turned on; optical module hardware failure or aging.
Failure Point: Failure to establish a test connection or the instrument does not recognize the test module
Cause Analysis: The 7 internal coaxial cables on the side of the instrument are not correctly connected as required; the plug-in test module is not securely installed or is faulty itself; incorrect software IP address settings (Windows IP and Unit IP are not in the same subnet) leading to communication failure.
Failure Point: Abnormal measurement readings (e.g., excessive bit errors, inaccurate power)
Cause Analysis: Drift of the internal reference clock source or module internal calibration parameters; performance degradation of the optical attenuator or receiver circuit; the instrument has not undergone external metrological calibration for an extended period.
Failure Point: System software runs slowly, freezes, or communication interfaces (GPIB/USB/LAN) malfunction
Cause Analysis: The built-in Windows XP system runs slowly or is infected with viruses; insufficient hard disk storage space or bad sectors; communication interface driver abnormalities, or physical damage to the interface chip due to electrostatic discharge or power surges.
Failure Point: Unresponsive keys or display failure
Cause Analysis: Physical wear or oxidation of contact points on front panel keys due to frequent use; loose display ribbon cables, poor contact, or aging and damage to the display itself.
