Hi
The normal term for a gizmo that multiplies and then mixes down is an error
multiplier. They were a very common lab item back when I had more hair than I
do now.. Various people made them in the 1950's and 1960's.

x27;ll also find that the sampling detectors in
the bricks have some "interesting" time domain issues as well

Strictly for adjusting and comparing two 10 or 5 MHz sources I use the
circuit from the Austron 2110 that takes a 5 MHz input and through mixing
generates 5.0005 MHz subsequently devided down to 1.0001 MHZ. Mixed with the
other input at 1 MHz the resulting difference is 100 Hz which a

I can speak to the Freq West PLOs. They, like the others, use a
sampling phase detector. In theory you could use any subharmonic of
the actual L-band VCO frequecy to get the loop to lock. I have used
freqs as low as 5MHz. But there are limitations. You must couple the
signal direct
