To better understand the performance of a home build counter a
comparison was done with a Picotest U6200A
The two channel home build counter was setup to measure the frequency of
the 10MHz output from a Rb on one channel and the 10MHz output from a
not so good OCXO on the other channel.
The
Fs an HP5065A, the best ribidium ever produced on the market. In perfect
condition with digital clock, complete with power cord. Xtal 00105.
Electrolytic capacitors replaced, otherwise in original condition.
1450.oo € shipping included Central Europe, for other countries to check the

I suspect we may be the only ones interested in these units. Can we connect

With respect to Murphey Surplus they have been around for 30+ years. I
think if you reach out to them they will take care of the issue of
wrong/bad units. I have one damaged top

I wouldn't assume battery power - but this is where a phone call helps -

I was surprised that NPL (Teddington) steers MSF (Anthorn) based on the
signals received at NPL. While this steering seems less accurate than

As far as I know, every OCXO and most everything else has its own
internal supply
