The Rohde & Schwarz SMU200A is a modular vector signal generator delivering independent dual-path RF and baseband signal generation within a single 4U chassis. It supports frequency operation from 100 kHz to 2.2, 3, 4, or 6 GHz across the primary RF path, with optional secondary path coverage to 3 GHz. The instrument executes complex modulation including AM, FSK, PSK, QAM, and vector formats alongside real-time arbitrary waveform generation with up to 64 MSamples memory and 200 MHz RF bandwidth.
