Correct. 85685A, a very expensive (then and now) piece. The problem
there was to limit the impulse bandwidth of the frontend, harmonic
response was not a concern.
In general, if you want to reliably measure harmonics with a S/A, you
have to cancel the fundamental, either with a notch or low pass filter.
Right (except I suppose that high pass, no low pass :) )
