Care of Test Cable Assemblies
Proper use and care of your test cable assemblies will yield positive results including:
• longer life
• higher performance
• better repeatability
Performing the routine inspection and cleaning of the test cable assemblies, especially the
connectors, is very important to making the best possible measurements.
Connector Mating
Alignment of the center lines of the connectors of the test cables with the test set and DUT
connectors before mating is important. It is possible to start the threads on the connector nuts
without good alignment, but this will result in bent pins and damaged inserts. Resistance
encountered while turning the connector nut may be due to one of the following:
• The pins are not aligned.
• The coupling nut is cross-threaded.
• The connector (or its mate) has been damaged by excessive torque.
Stop and determine the reason. To proceed without doing so risks the destruction of the
assembly and the mating connector.
Holding a connector nut stationary while screwing the socket into the connector will wear
away the connector plating and score the connector parts. If the pins lock up, serious damage
can be caused.
Connector Torque
Make sure to grasp the body of the connector before applying final torque. If the connector
body is allowed to rotate with the nut, the connector plating, outer interface rim, or pin
assembly may be damaged. Excess torque applied to the connector will be transferred to the
cable assembly. Refer to
“Connector Care for RF & Microwave Coaxial Connectors” on
(also included in the multiport test system online Help) for more information.
