Abstract :
A portable amplitude-modulation (AM) and phase-modulation (PM) noise standard has been developed for carrier frequencies of 10.6, 21.2 and 42.4 GHz. The noise level from the carrier 1/2 Sφ(f) (phase noise) or 1/2 Sa(f) (amplitude noise) is -122.6 dBc/Hz at 10.6 GHz, -119.6 dBc/Hz at 21.2 GHz and -116.3 dBc/Hz at 42.4 GHz. For Fourier frequencies of 1 kHz to 10 MHz the added noise is flat with an uncertainty of ±0.25 dB. The uncertainty of the noise level for Fourier frequencies of 1 kHz to 100 MHz is ±0.5 dB. The residual PM noise floor between the signal and reference outputs at 100 MHz is less than -182 dBc/Hz
