Hi:
Problem solved.
The Ultra Stable Oscillator coarse tuning pot needed adjustment.
Once it was adjusted to put the strong center peak into the center of
the control voltage range s/n 1013 locked right up.
This procedure is described in appendix A of the manual. But the
procedure for the S/2

Brooke, don't know if this will be of any help as you're looking at your
4060 (and it may or may not be of any interest to the group as a whole)
but I'm about 15 days into what I hope will be long-term monitoring of
my two 5061As and one 5065A against GPS.
I'm using a setup that should be parti

Hi Tom:
I think the problem is related to the FTS4060. During the brown out my
computer and the SR620 counter reset, but the two green LEDs on the 4060
stayed on, at the time my thought was "cool". But the yellow "Align"
light behind the door has turned on and so far I have not been able to

Hi:
After Tom helped me a month ago to get the trigger level correct for 50 Ohm
loaded TTL (1.25 volts), I've been seeing no aging on the FTS4060 s/n 1013 and
have been tweaking the C field and all was going well, but today (heavy rain)
the jitter on each 500 second average has jumped up from a
