P275 FM Analyzer

The P275 FM Broadcast Analyzer is a stand-alone low-cost solution for FM broadcast analysis. It provides FM modulation and MPX measurements in standard FM radio band 76.0-108.0 MHz through the antenna input. Built-in LCD display and control interface allows to measure and collect data in terrain without need of a PC computer.

This kind of analyzer is an essential equipment for all FM radio stations to ensure compliance with basic technical broadcast standards and to accomplish the highest audio quality possible.

This compact FM analyzer is designed for fixed installation as well as for daily work in the field. Durability and immunity is supported by laser machined aluminium case with internal steel frame. Front panel is covered with acrylic glass.
