[Test-Equipment] Quartz Oscillator Adventures

John,

That would be the double oven 10811D/E?  That is the same oscillator
that the Z3801A uses. I recall reading (somewhere) that these
oscillators were selected for ageing and stability characteristics
for certain applications. You have a superb one in your 8662A.

If anyone is interested in the Z3801A standard,
a great starting point is:

I'm really impressed by the HP 10811 source in my 8662A.  I calibrated it
against GPS about a year ago, and it's still within 1*10E-9.  Less than 1 Hz
drift at 1 GHz over a year.  Never seen one do that before.

I was going to slave the 8662A to my Trimble Thunderbolt clock, but realized
there was no point when I saw how stable its own clock source was.

Of course, this unit runs on a computer UPS which is never, ever switched
off.
