For a fast and accurate frequency response compensation of a spectrum analyzer, the frequency-dependent control values for controlled amplifier are stored as digital values in a digital memory, and in between the memory and a sweep generator of a heterodyne oscillator, an analog-to-digital converter is disposed to provide frequency-proportional digital values of which the associated frequency-dependent control values stored in a memory can be selected and supplied to the controlled amplifier.
