ABSTRACT:
A spectrum analyzer is provided with means for setting the level of an input signal applied to the mixer of the frequency converter circuit in the spectrum analyzer to an optimum level, i.e., such that the relative amounts of harmonic distortion and average noise in the displayed spectrum are balanced, the input level setting being established on the basis of the current reference level and resolution bandwidth settings.
