Now at the stage where two of the three 3210's are working. The fault
that was blowing the line fuse turned out to be a shorted reservoir cap.
Managed to find an Ebay seller in Greece with exactly the same voltage,

I forgot to tell you to uncheck the download manager thing, that's why it is
downloading .exe.
Anyway, i ran some test today, i unplugged the high voltage driver and found
out that instead of 10 volts on one output i now have 13-15 volts, which means
that either it is a bad filter, or the pwm
yes I got these executable too, and therefore did not continued

As always step 1 - check voltages/regulators. Remove bridging components

Did a major breakthrough!
Obviously it was my fault, by mistake i swapped two connectors.
My luck is that the power board has some safety elements.
OK, now with the connectors in correct position
I have 8.5 and 17 volts on the outputs.

Hi Tom,
Just catching up and time for an update on progress. Had had to put the
faulty 3210 to one side this week to get some work done, but a couple of
developments meantime: First: Put an enquiry on the Oscilloquartz web
enquiry form a week or so ago and they sent me the full 3210 pdf manual
Magnus,
here is at least some information on the B-5400:
http://tf.boulder.nist.gov/general/pdf/26.pdf
That is the paper mentioned in the 3200 manual.
Btw. do you have any information on the B-1325?
Cheers,
Adrian

You should post it on time nuts. Do you know the specs on these? I have not

I have one of those modules but in a Telecom Solutions wrapping.
It seems like for your purposes, at least bypassing the output synthesis
would be a good thing.

If you have tube-life and not other issues, it's about the same.
Also works for rubidiums, as the loop aspect here is essentially the same.
There can be *other* issues. For the 5060A for instance, you might need
to also adjust the crystal filter of the OCXO, as that too drifts out of
range, so
Is there a similar 'bring it back to life' procedure for the 5061A?

First turn the operational mode setting from off to second step (ocxo +

Then, as the oven have stabilized, switch it over to third step, the
