The 8662A derrives it's 640MHz o/p from a (very) good 10MHz crystal osc.
which is then doubled 6 times and filtered at the 40MHz and 160MHz
stages with crystal filters. The problem with using so many multipliers
is that the noise

Don't know if you got an answer, but this is my understanding :-
The 11729B needs to have an external 640MHz reference input for
measurements above 1280MHz.

I saw that, but (a) the 11729C already did enough damage to the exchequer,

That's something I meant to ask you about, Rick, as a follow-up to an old
Usenet post of yours from 1995. From looking over the block diagram in the
11729B-1 app note, it appears that there is no reason why you couldn't feed

There are a couple of near-mint-looking HP 11729C carrier noise test sets on
eBay right now. They are sold by nouturnhere, a great seller in my
experience. They have the AM noise detection option (130) and all of the
