4 PRECAUTIONS
DO NOT touch RF Connecting parts of components with bare
fingers.
Even the smallest amount of sweat on the conductors can cause
oxidation, which will reduce the performance of the element and
can cause PIM. Elements Included:
• RF Port of PIM31
• Low PIM Cables
• Low PIM Load
• Low PIM Adapters
• All components in the transmitting path of the System under
Test or DUT.
DO NOT switch on RF power without load or antenna attached.
Switching RF power on without termination, results in the full
transmitted energy of the test system being reflected back into the
test system. This can overstress the system cause damage. The
load ensures energy flow from the test system to the load, which
transforms all RF energy into heat.
DO NOT operate the PIM31 in any active systems.
The PIM31 is a very sensitive Test System that allows testing and
analyzing passive RF components. Under no circumstances should
the tester be operated when the RF path is active, no outside
carrier signals should be present in the RF path under test. This
includes all active signals even when they are operating in different
frequency bands. Operation with active signals present will cause
serious damage to the instrument.
