Anritsu Co. has announced a passive intermodulation (PIM) analyzer that covers the 900MHz band. The MW8209A PIM Master is geared for use with Anritsu's handheld analyzers and comes with the company's Distance-to-PIM technology, the only tool on the market that according to the company can determine if the cause of PIM is at the base station or in the surrounding environment.

Field engineers and technicians can use the MW8209A to help ensure optimum performance of UMTS Band VIII and LTE Band 8 networks by locating PIM faults before intermodulation distortion adversely affects signal transmission. The device has been designed to be integrated with Anritsu's handheld instruments, including the S332E/S362E Site Master cable and antenna analyzers, MS2712E/MS2713E and MS272xC Spectrum Master handheld spectrum analyzers, MT8212E/MT8213E Cell Master handheld analyzers and the MT8221B/MT8222A BTS Master handheld analyzers.

Field personnel can use PIM Master to generate two high-power tones in the transmit band of a base station, and use any of the compatible handheld analyzers 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 analyzers, the location of the measurement can also be recorded.

A unique feature of the MW8209A is its 40W testing, compared to alternative methods that only measure at 20W, noted Anritsu. 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 multicarrier antenna system or discover microscopic arcing in connectors.

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. It also provides the detail and insight that can accelerate repairs, control repair costs and help plan budgets. Historical data can be used to monitor a site and determine if corrections need to be made before a failure results in dropped or blocked calls.

The MW8209A PIM Master has a delivery of 4-6 weeks ARO.
