High-power, battery-operated portable PIM test analyser

December 13, 2012 // By Julien Happich
The PIM Master MW82119A passive intermodulation (PIM) test analyser from Anritsu is battery-operated, portable and one quarter the size and half the weight of alternative PIM test solutions according to the manufacturer.

The MW82119A offers the inherent advantages of PIM Master, including 40W testing and Anritsu's patented Distance-to-PIM (DTP) in a compact housing suited for difficult-to-access sites, such as Remote Radio Head (RRH) installations and indoor Distributed Antenna Systems (DAS).
Six models are available to address major frequency ranges, including the upper and lower 700MHz bands, 850MHz, 900MHz, 1800MHz, 1900MHz, and 1900/2100MHz. All six PIM Master MW82119A analyzers incorporate DTP technology, allowing tower contractors, maintenance contractors, and wireless service provider field technicians to pinpoint the location of PIM problems, whether they are on the tower or outside the antenna system. A flexible power adjustment capability allows a single MW82119A analyzer to conduct PIM testing on low-power DAS systems, as well as high-power Macro Cells.
The unit is designed to withstand transportation shock, vibration, and harsh outdoor test conditions associated with cell site deployment, installation and maintenance. Testing is simplified by the analyzer’s ability to save and recall test set ups for standardized testing, and limit lines can be set for visual and/or audible pass/fail criteria. Anritsu’s Line Sweep Tools can be used to manage PIM Master MW82119A measurements, and generate reports that combine VSWR data as well as PIM data into a unified site report. PIM measurements can be tagged with the GPS location when the analyzers are equipped with the GPS option.
