DO NOT connect or disconnect any accessory or component
of the test setup with RF power switched on.
Even at low RF power levels, spark discharge can occur with
sudden energy flow or flow disruption.. Spark discharge - must be
avoided, because it will alter the surface of the pins and connection
areas. “Burned” surfaces will not only reduce the performance of
the component, but can also cause permanent PIM.
DO NOT operate test system and load without connector
savers.
All connectors wear out when used frequently. Connector savers on
the RF Port and the load port(s). help to prevent costly repairs of
the PIM31 Boonton connector savers offer negligible influence on
measurements. We suggest to always leaving the connector saver
attached to the tester / load to ensure they are always utilized.
Replace them when they wear out, and their performance
deteriorates. For order information please refer to the chapter
accessories.
DO NOT mount components directly on the PIM31.
Always use a cable between PIM31 and DUT. The connector of the
PIM31 is a high quality, high precision element. It is designed to
withstand tangential forces that occur when connector savers or
cables are torqued on with the appropriate force. The RF Port
connector is not designed to support the weight of a component.
