The Rohde & Schwarz CMT84 Radiocommunication Tester is a portable instrument for testing analog and digital radio communication equipment across 0.1 MHz to 1000 MHz. It delivers transmitter and receiver characterization, signal quality assessment, modulation analysis, and compliance verification for AM, FM, and cellular radio technologies including AMPS, TACS, NMT 450, NMT 900, Radiocom 2000, and Network C. The CMT84 executes full-duplex deviation meter operation, VSWR measurement, and detailed signalling analysis with telegram exchange display showing type, contents, blocks, bits, and timing information. Dual-mode operation—manual and automatic—accommodates both bench analysis and production workflows.
