The iPA Series Passive Intermodulation (PIM) analyzer is the first battery-powered PIM Test Analyzer versatile enough to support multiple test scenarios such as testing at the top of the tower, the base of the tower, roof top and in-building for DAS systems. This IEC compliant 20W, rugged, battery operated design includes an iPad Mini for remote control, a hands-free dynamic testing scenario that is safe and convenient. Add the optional Range to Fault (RTF) Module to quickly identify the location of PIM and Return Loss sources.

This PIM Analyzer enables network operators to improve site performance by finding and eliminating sources of passive intermodulation at the cell site. An intuitive touchscreen interface is also available for local control, performing tests and generating site reports.

The iPA is designed to carry out reverse Passive Intermodulation (PIM) measurements in accordance with test setup one of IEC 62037. PIM occurs in passive devices whenever two or more RF signals encounter non-linear electrical junctions or materials. The interference generated is mathematically related to the localized downlink frequencies and can result in a noise rise in the uplink band of one or more systems sharing the RF infrastructure. The impact of PIM on the network performance can be severe, especially for wideband systems such as CDMA, UMTS or LTE.

PIM interference can lead to desensitization of the receiver causing increased dropped calls, increased access failures, pre-mature hand-offs, decreased data transmission rates and decreased system coverage and capacity. Any component in the RF path can be the source of the PIM interference including antennas, TMAs, diplexers, duplexers, surge arrestors, cables, and connectors. In addition, loose mechanical connections or rusty surfaces external to the antenna system can generate PIM when subjected to high radiated RF power.

Two synthesized carriers can be set to specific frequencies in the transmit band. With the RF output switched on, these tones will be present at the test port and stabilized to the predefined output level. The resulting third and fifth order intermodulation product is automatically calculated and the receiver is tuned to the required product. The detected voltage is processed by a microcontroller and the relevant reading shown on the display unit.
