Anritsu PIM Hunter Test probe

Anritsu expands its field test portfolio with the PIM Hunter, a passive intermodulation test probe that helps field technicians more quickly discover the precise location of external PIM sources at cell sites. Designed for use with the PIM Master, Spectrum Master and BTS Master handheld analysers, the test probe enables field professionals to use traditional interference hunting techniques to accurately locate external PIM sources for optimum wireless network performance.

The probe provides a simple, efficient method of addressing a growing concern for mobile operators. It complements the company’s 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 the product to detect the exact source of the external PIM. Integrating the product with any of the compatible handheld analysers 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 to 2700 MHz frequency range. With the test probe connected to a spectrum analyser 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.

Unlike traditional near field probes, the product utilises patent-pending technology to return a consistent signal level regardless of probe orientation with respect to the PIM source. Accuracy is further assured because the probe is manufactured using low PIM construction techniques, so the probe does not act as a PIM source. A 90 cm extension shaft allows the test operator to remain a safe distance away from antennas under test.
