*** I wonder if the noise of the K3/P3 could be measured using a

signal source - then once that's known, you would subtract the K3/P3's
noise from the
total noise measured from the DUT.
I had a book somewhere with plans for a really clean single-frequency
signal source. It used several
identical crystals; one as an oscillator and then some more as a filter
to clean it up.
