Test probe finds external interference sources in wireless networks
The PIM Hunter is a passive intermodulation test probe that helps field technicians more quickly discover the precise location of external passive intermodulation (PIM) sources at basestation sites. Designed for use with Anritsu’s PIM Master, Spectrum Master and BTS Master handheld analyzers, the PIM Hunter test probe enables field engineers to use traditional interference hunting techniques to accurately locate external PIM sources for optimum wireless network performance.
PIM Hunter complements Anritsu’s patented Distance-to-PIM (DTP) technology that determines the distance between the antenna and external PIM so that 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 the compatible handheld analyzers that have 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.
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.
Unlike traditional near field probes, the PIM Hunter uses 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 0.9 m (35in) extension shaft allows the test operator to remain a safe distance away from antennas under test.
The PIM Master MW82119B is a 40 W, battery-operated PIM analyzer with a line sweep capability that can fully certify cable and antenna system performance by measuring PIM, Distance-to-PIM, Return Loss, VSWR, Cable Loss and Distance-to-Fault. The BTS Master high-performance handheld base station analyzers have been specifically developed to support 4G/3G/2G and WiMAX networks, as well as CPRI RF and BBU emulation.
