Anritsu introduces the MW8219A PIM Master, a high performance PIM analyser that can accurately and quickly locate the source of passive intermodulation (PIM), whether it is at the base station or in the surrounding environment.
Designed as an innovative field test solution, the PIM analyser initially covers the PCS and AWS cellular frequency ranges with an 850MHz version to follow soon.
The MW8219A PIM Master provides field personnel with a test system that can help ensure optimum network performance and also locate PIM faults before intermodulation distortion adversely affects signal transmission.
PIM Master has been designed to work with Anritsu’s S332E/ S362E Site Master, MS2712E/ MS2713E Spectrum Master and MT8212E/ MT8213E Cell Master handheld analysers as well as the MT8221B/ MT8222A/ MT8222B BTS Master analysers.
Field personnel can use the PIM analysers to generate two high-power tones in the transmit band of a base station, and use any of the handheld analysers to measure the 3rd, 5th or 7th order intermodulation products in the receive band that travel down the same cable.
Using the GPS option available on all the analysers, the location of the measurement can be recorded as well.
A unique feature of the MW8219A PIM analyser is its 40 watts testing, compared to alternative methods that only measure at 20 watts.
Using double the power allows the PIM Master to locate intermittent failures due to light corrosion, high-traffic loading or changing weather conditions. It also permits users to find faults in a multi-carrier antenna system or discover microscopic arcing in connectors.
A proprietary technology called Distance-to-PIM developed by Anritsu for use with PIM Master helps users pinpoint passive intermodulation faults, eliminating the unknown of whether the PIM source is from the antenna system or surrounding environment.
Simple, immediate and accurate, Distance-to-PIM simultaneously informs the user of the distance and magnitude of all the PIM sources, both inside the antenna system and beyond the antenna.
Distance-to-PIM testing provides the detail and insight that can quicken repairs, control repair costs and help plan budgets.
