Preventive Maintenance
Preventive Maintenance
Preventive maintenance consists of two tasks. It should be performed at
least every six months—more often if the instrument is used daily on a
production line or in a harsh environment.
Clean the CRT
Use a soft cloth and, if necessary, a mild cleaning solution.
Check the RF
Front Panel
Connectors
Visually inspect the front panel connectors. The most important
connectors are those to which the DUT is connected, typically the RF
cable end or the PORT 1 and PORT 2 connectors. All connectors should
be clean and the center pins centered. The fingers of female connectors
should be unbroken and uniform in appearance. If you are unsure
whether the connectors are good, gauge the PORT 1 and PORT 2
connectors to confirm that their dimensions are correct.
