A measuring circuit for phase measurement of pulsed high-frequency signals having a phase detector (2) which has a measuring signal input (1) and a reference signal input (3) and which generates from the phase difference between measuring signal and reference signal, a phase difference signal corresponding to a sample and hold circuit (4 ) is fed, which produces therefrom a DC voltage. The DC voltage is a phase correction memory (8) is entered, in which a correction of the non-linearity of the phase detector. At the measuring signal input (i) and the reference signal input (3), an amplitude extraction circuit (6) is connected, which determines the amplitude of the measurement signal and the reference signal. To the output of the amplitude extraction circuit (6), an amplitude compression memory (10) is connected, which performs a controllable with the signal amplitude of the density characteristic curve corrections. The outputs of the sample and hold circuit (4) and the amplitude compression circuit (10) control the phase correction memory (8), which corrects the distortion of the phase characteristic.
