Frequency range: 9 kHz to 3.3 GHz  0.1 Hz frequency resolution SSB phase noise: <-122 dBc/Hz (at f = 1 GHz, Delta f = 20 kHz) Setting times: <10 ms High level accuracy (deviation <0.5 dB at levels >−120 dBm) High reliability through electronic attenuator Digital frequency and level sweep AM/FM/Phase Modulation 3-year calibration cycle GPIB and RS-232 interface The Rohde & Schwarz SML03 signal generator is an electronic instrument that generates repeating electronic signals. It contains an electronic oscillator, a circuit that is capable of creating a repetitive waveform. It offers all features required of a state-of-the-art general-purpose signal generator: wide frequency range, large variety of modulation functions and high reliability.
