The PIM Hunter 2000-1884-R from Anritsu is a passive intermodulation test probe that operates from 600 MHz to 2700 MHz. It helps field technicians quickly discover the precise location of external PIM sources at cell sites, typically within a few centimeters. With the PIM Hunter test probe connected to a spectrum analyzer in burst detect mode and an appropriate band-pass filter installed, technicians can track and locate IM3 signal sources that cause PIM. When the probe tip comes in close proximity to a source, the PIM value increases by as much as 30 dB, indicating the precise location of the interferer.
The PIM Hunter returns a consistent signal level regardless of probe orientation with respect to the PIM source. The probe is manufactured using low PIM construction techniques so the probe does not act as a PIM source. A 35-inch (0.9 m) extension shaft allows the test operator to remain a safe distance away from antennas under test and the probe tip has a diameter of 1.86 inches.
