P275 FM Broadcast Analyzer
The P275 FM Broadcast Analyzer is a stand-alone compact solution for FM broadcast analysis. It provides complete FM modulation and basic AF spectrum measurements in FM radio band through the combined antenna and MPX input.
Built-in OLED display and control interface allows to measure and collect data directly in field without need of any PC computer. USB interface and the control software provide a possibility of remote control, data viewing and automated data logging.
This kind of analyzer is essential equipment for all FM radio stations to ensure compliance with basic technical broadcast standards and to accomplish the highest audio quality possible.
Typical applications include: FM broadcast equipment setup and maintenance, verification of compliance with related technical standards as well as diagnostics, repairing and development.
