Microgen FME100 FM Modulatie and AF Spectrum Analyser     
    
We are proud to announce the FME100 FM modulation analyser. This compact unit has been designed for precision monitoring of FM Radio Broadcasts. Connected to a standard Windows PC USB port, the user friendly interface displays comprehensive modulation data, for live ‘off-air’ analysis.

The unit has been fitted with two AtoD convertors, one 16 bit sampling the Baseband signal, and a new dedicated 12 bit convertor for measuring the Multipath distortion.

With an advanced ultra linear demodulator, containing dual feedback loops, maintain accuracy over time and temperature, by comparing deviation amplitude and phase to a 20ppm voltage reference band-gap diode. This effectively provides a calibration free instrument. The demodulator itself is virtually distortion-less, leaving only the IF filter response to determine the demodulation.

The supplied appliction, iLogV7, now Windows 8.1 and 10 compatible, provides full GPS support, with the latest Mark 4 high performance SiRFstarIV GPS magnetic receiver modules.
