I'll likely do some more testing with the 50 ohm load in place and see how
stable this unit is before investing more time in this.

Steve,
After you're done chuckling, note that one man's "utterly
insignificant" is another group's passion.
A 6 foot person vs. 98 million miles is 6 / (9.8e7 * 5280),
or 1.16e-11, a unitless number that's well within our range
of expertise and fascination; neither utterly nor insignificant.

Hi,
I have a copy of the retrofit pages that went with the 10544A install for
the HP 5245A.
There were LOTS of these installed in the 5245 series after the original
oscillators started failing.
Give me a day or so to hunt it up and I'll share it.
It has the schematics of the interface board.

Also a 1 sec time exposure.

My favorite watch is to stand outside on a quiet night and watch
the snow fall silently. It is a rare time-less moment.
Best wishes for the solstice celebration of your choice, or as
we used to say 60 years ago, Merry Christmas.

An Omega Seamaster here. It was losing about a minute a month when it went
back to Switzerland for routine cleaning, etc. Now it is losing about 2
seconds a week.
And that is plenty good enough for a mechanical movement of modest cost.

Odd I see the oscillator is 1 Mhz driving various ddas as they used to call

Did not think a 10544 could work in one of these counters.
Must have been a later version.
