• Switch RF Power ON

• The PIM Signal(s) should be at a level below -160 dBc

If the reading is higher (lower negative value), switch RF OFF, disconnect

connections and re-connect them.

Repeat test

If the reading is still above -160dBc replace low PIM cable and retest.

Hint: Low PIM cables wear out with use. If a cable does not

longer perform in the desired way, dispose of it and replace it

with a new cable. Worn out cables can cause unnecessary work

and costs. Trying to repair a base station with a worn out cable

will lead to no avail.

• Switch “RF Power OFF

• Set the PIM 31 to Field Mode

• Since the PIM 31 test system is connected to a low PIM load (not to an

active antenna), the RSSI value shows the noise floor of the instrument.

• RSSI should

be below -130dBm
