The Rohde & Schwarz SMJ100A is a vector signal generator engineered for research, development, and production environments requiring high signal fidelity across multiple digital standards. It delivers 200 MHz RF bandwidth through an I/Q modulator, with frequency coverage from 100 kHz to 3 GHz or 6 GHz depending on configuration. The instrument combines fast frequency settling—under 5 ms in standard mode, under 450 µs in List mode—with exceptional phase noise performance of typically -133 dBc at 20 kHz offset (1 GHz carrier, 1 Hz bandwidth) and wideband noise at -153 dBc CW or -146 dBc in I/Q modulation.
