Signal Generator Runs Clean to 3.2 GHz

The R&S SMC100A is a compact test signal generator with a wide range of modulation formats and low phase noise in models operating from 9 kHz to 1.1 GHz or 9 kHz to 3.2 GHz. The single-sideband (SSB) phase noise is typically -11 dBc/Hz offset 20 kHz from a 1-GHz carrier, with broadband noise at -148 dBc. The generator boasts output power of typically +17 dBm or more across the operating frequency range, with level accuracy of better than 0.9 dB. The settling time for switching frequencies is under 5 ms in support of production testing. To ease communications testing, analog AM, FM, phase modulation, and pulse modulation are included in both versions of the signal generator.
