ABSTRACT:
An apparatus and a method for determining the error due to inherent PM and M noise in a noise measurement device. The apparatus is a calibration standard having a high frequency carrier source and a Gaussian noise source. The outputs of both sources are linearly combined by a power summer so that AM and PM noise components are equal at the output terminals of the calibration standard. To carry out the process of calibrating the calibration standard then determining inherent noise in a noise measuring device under test, the calibration standard includes means for switching to output a signal indicative of either the noise floor or a high frequency signal linearly combined with the output of a Gaussian noise source.
