Abstract
To measure phase noise of an output signal of a test specimen with a spectrum analyzer whose measuring branch comprises a plurality of serially-connected heterodyne stages, a compensation generator is provided which comprises a plurality of heterodyne stages arranged serially-connected in reverse order to that of the heterodyne stages of the measuring branch and which has an input oscillator which corresponds to a last intermediate frequency of the measuring branch; the output signal of this compensation generator being added to an output signal of the test specimen, having an approximate equal-value level and being approximately oppositely phased thereto, in an adder stage which is connected serially to the measuring branch.
