Introduction
This chapter provides a description of the MW82119A PIM Master. It also includes a brief description of preventive maintenance, calibration requirements, ESD cautions, and additional PIM Master documents.
Warning 
The Anritsu PIM Master is capable of producing 80 Watts of RF power in the cellular communications bands. Users must take precautions to minimize exposure to these RF fields:
Always terminate the output port of the test equipment into a load, a loaded line, or a line that will radiate or absorb the energy before beginning a PIM test.
Confirm that the PIM Master RF power is off after a PIM test.
Always confirm that the RF power is off before disconnecting a coaxial connection, otherwise RF burns may result. Immediate burns to fingers or eyes can result from exposure to live connectors.
RF power can be immediately turned off with the Emergency Stop button (item 3 in Figure: PIM Master Connection Diagram – Top).
Ensure that all antennas under test are placed so that no personnel are exposed to RF levels that exceed the maximum allowable exposure.

Instrument Description
Anritsu has developed the PIM Master to verify if receiver interference at a cell site is due to an intermodulation product of two or more transmit frequencies, also known as passive intermodulation (PIM).
The Anritsu PIM Master features patented technology – Distance‑to‑PIM. In just a few seconds, Distance‑to‑PIM can find the distance and relative magnitude of all static PIM sources in an antenna system and beyond the antenna. For example, Distance‑to‑PIM can find the location of the following fault conditions:
Dirty connectors
Corroded connectors
Over torqued connectors
Microscopic arcing connectors
PIM outside the antenna system
PIM is power sensitive, and as signal technologies develop, more power continues to be transmitted at cell sites. The PIM Master features up to 2 x 40 Watts of RF power to activate sources of PIM in the feed system as well as beyond the antenna.
