Anritsu Introduces High Power Portable PIM Tester
Anritsu has expanded its line of Passive Intermodulation (PIM) test solutions with the introduction of the PIM Master MW82119A, a high-power, battery-operated, portable PIM test analyser.
At one quarter the size and half the weight of alternative PIM test solutions, the MW82119A offers the inherent advantages of PIM Master. This includes 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 700 MHz bands, 850 MHz, 900 MHz, 1800 MHz, 1900 MHz, and 1900/2100 MHz. All six PIM Master MW82119A analysers 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 analysers also test at 40W, which allows the PIM Master MW82119A to locate faults that conventional 20W 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 MW82119A analyser to conduct PIM testing on low-power DAS systems, as well as high-power Macro Cells.
As with all Anritsu handheld test solutions, 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 ability of the analyser 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 analysers are equipped with the GPS option.
