La description

Key Facts This option improves the phase noise performance from typically ?135 dBc(1 Hz) down to -139 dBc(1 Hz) at 1 GHz carrier frequency, 20 kHz offset. Furthermore the nonharmonics are lower with this option. Additionally, the R&S®SMW-B22 option offers phase and frequency modulation.
