The Rohde & Schwarz CMS36 is a portable radiocommunication service monitor integrating signal generation and analysis for field maintenance and bench testing. Operating across 400 kHz to 1 GHz with 10 Hz frequency resolution, it delivers modulation analysis for AM, FM, and ΦM signals alongside an integrated power meter spanning 5 mW to 125 W. Two audio generators cover 20 Hz to 20 kHz, while a full-span spectrum analyzer and transient recorder capture signal events during testing.
