The analysers’ excellent measurement sensitivity of -135 dBm and their facility for setting transmit tone levels down to 24 dBm (250 mW) make them the ideal PIM instruments for in-building distributed antenna system (DAS) installations as well as conventional macrocell sites.

In addition, the PiMPro units offer special DAS test functionality, using their RF transmitters to aid the measurement, diagnosis and analysis of PIM for proving in-building DAS design, configuration and installation.

Capable of simultaneously measuring real-time PIM and return loss, the PiMPro analysers generate two tones with an output microwave power as high as 46 dBm (40 W), while the -135 dBm sensitivity and a residual PIM of less than 122 dBm ensure highly accurate readings.

Equipped with a bright 8-inch touch-screen display, the instruments feature an intuitive graphical user interface for easy system setup and rapid switching between different measurement modes, which include PIM and Return Loss, PIM versus Time, Frequency Sweep, DAS Test, RX Interference and PIMPoint (distance to largest PIM source). All measurements are carried out via a single test port, so there is no need to disconnect and reconnect any cables.

Optional features include a GPS antenna to allow location stamping on test reports and a smartphone app for remote control.

In addition to the standard range of PiMPro analysers, Link Microtek is also offering the PiMPro Tower series, which provide the same level of functionality from a compact, lightweight backpack-style case.
