Test probes precisely track causes of interference

December 01, 2016 // By Julien Happich
Designed for use with Anritsu’s PIM Master, Spectrum Master and BTS Master handheld analyzers, the PIM Hunter passive intermodulation test probe enables field professionals to use traditional interference hunting techniques to accurately locate external PIM sources for optimum wireless network performance.

It complements Anritsu’s patented Distance-to-PIM (DTP) technology that determines the distance between the antenna and external PIM. A technician can walk along the arc of that distance with PIM Hunter to detect the exact source of the external PIM.  Integrating PIM Hunter with any of the compatible Anritsu handheld analyzers featuring Burst Detect Sweep Mode creates the tool set required to precisely identify external PIM sources for faster site repair. It is especially useful for detecting PIM on rooftops, the most common location for network densification in urban environments. PIM Hunter has been custom designed to support external PIM identification over the 600 MHz to 2700 MHz frequency range. 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.
