Dear fellow time-nuts,
I get something like ADEV(1s)= 5E-11 when comparing it against my 10 MHz
using the TS-105A in double-mixer setup. The TS-105A isn't the ultimate
tool by any sense of the word, but it is nice to be able to use it as
part of an early diagnosis since it is very "direct".
The other HP5065A is a bit more of a challenge, so I will have to work
more on the PSU side of it first.
Anyway, I would apprechiate some experience with fault diagnostic and
trim-up on HP5065A so I can get these back into spec. It always takes a
bit longer when new to them. All the signal checks look healthy now, so
it is only this minor issue.
Sigh. Reading the pinning incorrect numerous times prohibited me from
observing the obvious... that the Continous Operation lamp is out... :P
Thus I've been spending quite some time in vane... ah well. I know this
beast better now.
Managed to tune the multiplier up.
So, lids on and just a stable measurement before lifting it off the
table and see what other rubidium I will play with for the rest of the
evening.
Will need to hook up an ADEV rig again.
Cheers,
Magnus
