True PIM analysis over fibre reduces test costs and time

Anritsu Company has introduced the IQ Fiber Master MT2780A multi-port CPRI-based RF and PIM analyser that is the first instrument to deliver true PIM analysis over fibre and present RF spectrum results acquired from IQ data. The device decreases test costs and time by giving field technicians, field engineers, and third-party contractors with a single instrument to conduct RF interference measurements and PIM troubleshooting on LTE-based systems employing CPRI front haul infrastructure.

The device uses patented PIM over CPRI and RF over CPRI measurement abilities that enable tests to be carried out on the ground, significantly decreasing tower climbs. Field engineers and technicians can utilise the device to scan the uplink RF signals of an RRH for in-band interference while simultaneously carrying out PIM over CPRI measurements. Supporting all Tier 1 LTE base station radio manufacturers, this single instrument solution can ascertain if KPIs are being influenced by interference or PIM.

The device also works as a band-less PIM testing solution that can be a carrier’s first test tool when distinguishing an interference issue and its location. This assists in determining the most efficient course of action to follow.

All LTE bands are supported by the device. Extremely compact and lightweight, it weighs just 1kg (2.2lbs) and measures 185mm x 133mm x 55mm (2.1" x 7.3" x 5.2"), so it fits in the palm of the user’s hand.
