[time-nuts] Racal-Dana 1992 switches

[Charles S. Osborne]

Bill,

I guess my reason for wanting to see beyond 0.001 Hz is the usual, I have
reached a limit and wonder if the equipment I have is capable of more, if I
just understood the more esoteric functions I seldom use. The Racal seems
like my scientific calculator.. lots of shift functions that might be hiding
some useful capabilities with a little coaching and study.

Just saw Pete's answer, and I do have a PTS160 synthesizer. So the locked
offset idea is do'able. Have mixers, phase detectors, but may need more info
on the zero crossing detector opamp portion if you could point me in the
right direction.
