‪@InovonicsBroadcast‬ The 541 is Inovonics fourth-generation FM Modulation Monitor. It delivers a wealth of information about the transmitted signal in terms of the RF carrier and all subcarriers, the audio component defining the technical quality that the listener hears, and full decoding of RDS data and SCA audio.
The all-digital 541 combines detailed DSP signal analysis with a menu-driven touch­screen display, plus Webserver-based total access for remote operation, including measurements, graphical data and direct Web-browser audio monitoring of the off-air program.
