Anritsu's MW8208A PIM Master is a test solution that brings the company's patented Distance-to-PIM technology to 850MHz cellular band applications. Distance-to-PIM helps make the MW8208A a comprehensive trouble-finding tool that allows field technicians and engineers responsible for deploying, installing, and maintaining wireless networks to quickly locate the source of passive intermodulation (PIM), whether it is in the base station antenna system or in the surrounding environment. With the new solution users can uncover the distance and relative magnitude of all static PIM faults simultaneously, including those resulting from dirty connectors, corroded connectors, over-torqued connectors, and microscopic arcing connectors. It can also accurately locate PIM outside the antenna system. The instrument generates two high-power tones in the transmit band of a base station and can measure the 3rd, 5th, and 7th order intermodulation products in the receive band coming down the same cable. Utilising the GPS feature on the Anritsu handheld analysers, users can record the location of the measurement.
Another advantage is the 40W testing, compared to alternative methods that only measure at 20W. Utilising 40W simulates real-world power that activates the PIM that might not otherwise be activated by 20W systems.
