[time-nuts] Another GPSDO

[Joseph Gray]

Just an update.

I found that I didn't have another 24 VDC supply, so Mouser to the
rescue. The supply arrived today.

I just finished wiring everything up and setting the Lucent boxes next
to my Z3801A. When I ordered the Lucent, I also ordered an HP antenna
splitter (shouldn't have sold the one I had, years ago).

It took 13 minutes from powerup to get the On and STBY lights on. I
get a 10 MHz square wave and a 15 MHz sine wave out of REF 0.

I just did a couple of quick measurements with my scope triggering on
the Z3801A. The 10 MHz from REF 0 was initially low by 1.66e-10. Ten
minutes later, it is 2.77e-10 high.
