It is capable of off-air measurement of FM stations and it measures RF and audio quality. It has an RS232 connection to a standard PC. Software included allows to display 16 parameters and to make 24-hour logs of the radio performance.
It measures modulation, field intensity, carrier deviation, L & R audio level, effective integrated power, stereo phase vector, pilot level and frequency error. It offers L & R noise channel separation, a band scanner and a spectrum analyser. It measures modulation bandwidth, harmonic distortion and audio frequency response.
It makes its measurements without interrupting the transmission. It is suitable for a 19-inch rack or tabletop use.
