The Rohde & Schwarz CMS52 is a radiocommunication service monitor engineered for testing and servicing radio systems across 400 kHz to 1 GHz. It delivers comprehensive transmitter and receiver analysis through integrated spectrum monitoring, oscilloscope functionality, and continuously tunable distortion measurement. The instrument supports AM, FM, and SSB modulation alongside multiple signaling protocols including E-AMPS, trunked radio, POCSAG, ZVEI/VDEW, MPT 1327/1343, and FMS-BOS. A high-contrast backlit LCD display with large characters presents settings and measurement results simultaneously for field technicians and laboratory personnel alike.
