The Rohde & Schwarz CMTA84 Radiocommunication Analyzer combines signal generation and analysis in a single platform for testing radio communication systems across production, servicing, and field applications. Operating from 0.1 kHz to 1000 MHz, the instrument supports AM, FM, φM, and SSB modulation types with an RF synthesizer providing 1 Hz frequency resolution and an OCXO reference oscillator for stability. The CMTA84 integrates dual-mode operation—manual testing and fully automatic routines with integral program memory or external IEC bus control—eliminating the need for external controllers.
