Available for rent, the Anritsu PIM Master MW82119A 40 W battery-operated passive intermodulation analyser (PIM) allows users to quickly and easily determine the location of PIM faults with a high degree of accuracy. The MW82119A allows the operator to adjust power from 25 dBm for indoor DAS testing to 46 dBm for macro site testing, and is suitable for testing all types of antenna systems.

PIM shows up as a set of unwanted signals created by the mixing of two or more RF signals in a nonlinear device, such as in a loose or corroded connector, or in nearby rust. Other names for PIM include the ‘diode effect’ and the ‘rusty bolt effect’. Many symptoms could be indicators of PIM problems: receiver desensitisation (raised noise floor); Rx diversity alarms; spectral regrowth in the transmitter mask; excessive dropped/blocked calls; cell site coverage shrinking; complaints of interference from neighbouring cell site owners.

The compact, lightweight design makes the Anritsu MW82119A suitable for on-site testing of hard-to-access sites such as remote radio head (RRH) installations or indoor distributed antenna systems (DAS). Being battery operated also allows for PIM testing without heavy lifting or the need for long extension cords.
