High-power, battery-operated portable PIM test analyzer

Anritsu Company has expanded its line of industry-leading Passive Intermodulation (PIM) test solutions with the introduction of the PIM Master MW82119A, which claims to be the industry’s first high-power, battery-operated, portable PIM test analyzer.

One quarter the size and half the weight of alternative PIM test solutions, the MW82119A offers the inherent advantages of PIM Master - including 40 W testing and the company’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 700 MHz bands, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 1900/2100 MHz. 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. The analyzers also test at 40 W, which allows the analyzers to locate faults that conventional 20 W test solutions might miss, such as intermittent and power-sensitive PIM problems.

In addition to its compact, lightweight design, the PIM Master MW82119A has other advantageous features for wireless professionals responsible for today’s field-testing requirements. For example, a flexible power adjustment capability allows a single analyzer to conduct PIM testing on low-power DAS systems, as well as high-power macro cells.

The PIM Master MW82119A 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. The company’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.
