P275 FM Analyzer Module
The P275 FM Broadcast Analyzer is a 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. Optional 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 board is ideal for embedding into an enclosure or customer's
product to add FM modulation measurement and RDS decoding functions. It comes fully assembled and tested.
