The Anritsu PIM Hunter Probe 2000-1884-R is a test probe designed to locate external PIM sources at cell sites in conjunction with the Spectrum Master™ MS2720T or BTS Master™ MT8220T. By walking along the arc of the DTP distance from the antenna with the Anritsu PIM Hunter, technicians can pinpoint the source of the PIM typically within a few centimeters. The PIM hunting process begins with an Anritsu PIM Master MW82119B to inject two high-power test signals into the system under test. The test signals broadcast through the site antenna, exciting any PIM sources in the RF path. These PIM sources behave like CW transmitters radiating the IM3 frequency in all directions. With the PIM Hunter test probe connected to a spectrum analyzer like the MS2720T or the MT8220T and an appropriate bandpass filter installed, technicians can “hunt” for these IM3 signal sources along the arc of the distance provided by the DTP measurement of the PIM Master MW82119B. When the probe tip comes in close proximity to a PIM source, the PIM value increases by as much as 30 dB, indicating the precise location of the PIM source.
