Image And Out-Of-Band Response - HP 8566B Adjustment Manual

17. Image, Multiple, and Out of Rand Responses Test
Image and out-of-band responses are checked by setting the analyzer
center frequency to several frequencies across the analyzer range and
tuning a leveled signal source to the frequencies determined by the
tuning equation, Fsiz = nFLof F IF. Input signals at these frequencies
will excite all possible image and out-of-band responses for a given
1st LO frequency and all positive integer values of n. In this test,
only values of n corresponding to the analyzer mixing modes are
used. Multiple responses are checked by applying an input signal
and measuring the response at those center frequencies for which a
harmonic of the 1st LO mixes with the input signal.
