GENERAL INFORMATION 

 

Description 

 

The 

FMCS-1

 provides a complete solution for the Analog portions of the FM signal. The unit 

combines the features and functions of an RF amplifier, FM demod, stereo demod, RDS decoder, 
SCA decoder, and FFT spectrum analyzer in one product. Using state of the art DSP techniques all 
of the 

FMCS-1

 processing takes place in the digital domain, this results in FM analog 

performance that was previously not possible. 

 

Features 

 

 

Frequency Agile RF input 

 

AM & Sync AM Noise measurements 

 

HD RF carrier rejections filters to improve analog readings in the presence of HD carriers. 

 

FM Demodulation with 100dB 75 µsec SNR 

 

Variable Bandwidth Composite Filtering 

 

Stereo Demodulation with 100dB L/R Separations 

 

Full metering of Analog Peak and RMS values 

 

RDS Injection/Phase and Full Data decoding 

 

Two SCA Decoders 

 

RF, Composite, and Audio FFT Spectrum Analysis 

 

RJ-45 Ethernet Interface with remote PC software
