I just ordered some from Mouser in November, this is it:

They list 41 in stock, for 1 to 9 the price is $8.43

How precisely can you measure the period. You would be using the rising
edge as start time and stop time, with no dead time, i.e. measure the time
of every period?

This sort of behavior shouldn't be surprising at all. When you change
the EFC (especially by a fairly large amount to move it a few Hz), you
change the (transient and steady-state) operating points of the
circuitry, so it has to drift gradually to stabilize at the new
conditions. The effects
I have a few HP10811 and was thinking of making an interesting setup: A setup
where frequency is purposely offset by user defined amount by few Hz, and make
it selectable.
Under normal setup, I would use a potentiometer and EFC control the frequency.
When I adjust EFC, the frequency

Back quite a while ago, I went back and visited my buddies / ex-coworkers
at Motorola Franklin Park ( = the Motorola crystal / oscillator group). Based
on
my past experience with the yields on a “quartz bar to oscillator” fab process,
I asked:
How do you build a “6 sigma”

Hi
Which of the multitude of definitions are we talking about?
One very common definition looks at peak to peak jitter and does
not care about the center. Another looks at +/- peak to edge and
then uses the greater of the two numbers. Other definitions look
at RMS jitter and generally don’t
IIRC the latter
