The R&S SMA 100A 3 GHz Signal Generator features very low SSB phase noise of typ. -135 dBc (20 kHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth), typ. -140 dBc with the Enhanced Phase Noise Performance option (R&S SMA-B22). Wideband noise of typ. -160 dBc (>10 MHz carrier offset, f = 1 GHz, 1 Hz measurement bandwidth). Nonharmonics of typ. -100 dBc (>10 kHz carrier offset, f < 1500 MHz, with the R&S SMA-B22 option). High-stability reference oscillator as standard. Very low phase noise at low frequencies due to internal division of the fundamental frequency range (750 MHz to 1500 MHz) down to 6.6 MHz. Ideal for use in production with very short frequency and level setting times of <3 ms across the entire frequency and level range, <450 µs in the list mode. Frequency setting time of typ. <10 µs within a bandwidth of 40 MHz due to direct access to the DDS-based synthesizer (with the R&S SMA-B20 or -B22 option). AM, broadband FM/phaseM (R&S SMA-B20 or -B22), pulse modulation. Remote control via GPIB or LAN.
