Boonton's PIM 31 series test systems are precision analyzers for passive intermodulation generated in RF paths, components and assemblies. PIM 31 analyzers allow the detailed examination of components used in radio base stations, in-building-DAS installations and other systems transmitting radio frequencies.

The PIM 31 passive intermodulation analyzer emulates a base station radio by providing two signals, up to 20W each, thus following the IEC62037 standard for PIM testing. The frequencies of these carriers are variable within the band of the analyzer, allowing PIM 31 operators to select the optimal frequencies for their wireless systems.

Depending on the application it can be switched between a functional field diagnostic mode and detailed analysis mode with accessibility to all settings and readings. PIM 31 analyzers can be controlled by external mouse and keyboard or through the built-in touch screen display.
