Does anyone know the latest 5061A Manual part number and latest
print date?
I haven't seen anything after the 1978 edition that Had mentioned. If you
have a newer model 5061A (e.g. with the 10811 upgrade) you might look for a
5061B manual as well.
I have a 5061A that appears to be working
Have you played with the damping factor Brian?

John,
I have a copy of the 5061A manual designed for Serial Prefix 2506A, part
number 05061-9068 printed April 1985. My problem child is serial number
2428A. Fortunately, the manual includes 56 pages of manual change
information, all the way back to serial prefix 1740A, and appears to cover
it
Don't forget pulsars in this. Some of them rival atomic clocks and
they are a long way away and still line up nicely with our hydrogen
masers synchronized to caesium standards.

While it would be fun to know, the practical impact of such a change is
very, very small, to the level of being ignored. Considering of a major

When powered on, it locks properly after some 10 minutes and keeps
running until it jumps off by about +1E-7. That is, the 10 MHz output
then reads 10,000,001 Hz, and the red alarm light is on.

Pure speculation from a shade tree time-nut:
As my tube became weaker the unit became heat sensitive and would stay locked
if I keep the room cooler. It also did better on battery power vs the internal
supply. I attributed this to signal to noise level changing as the the tube
aged.

Sounds like the OCXO has a jumping problem, going too far out of range for
the CS loop to correct. Have you watched it for a long period of time with
the loop turned off?

John,
it's been a while since I digged deeper into it, but I remember having
had problems to adjust the OCXO to tuning voltage range center when the
failure mode was there. I was already suspecting an OCXO problem, but
haven't yet watched it for a long period of time. Now as you're
If it is always stable at 5x500.32 and has the lock light on than it
has to be in the PLL.

Joe,
Try swapping the A8 module and see what happens.

Another disadvantage of the Tight PLL system that only applies to
multichannel systems is that a dedicated reference oscillator is
required for each channel.
i.e. for an N channel system N reference oscillators are required.
If correlation techniques were to be employed then an N channel system
Yes, but if I press the align button when in 'failure mode', it just
wont lock.

When I watch the beam current while it is scanning, I'm observing the

Corby,
Thought of that but ran out of time. Will do tomorrow after I try the A14
