[time-nuts] HP OCXO in 5016A.....

[Brian, WA1ZMS]

Does anyone has any info on the HP-00105-6013 Series 1248

OCXO that is/was used in the HP-5061A?

 

I have a newly acquired 5061A that has "issues".

It has an FTS tube in it, and while there is beam current

and plenty of 2nd Harmonic, the alarm light does goes out,

but this unit is not yet a member of the "Green Light Club"

in that the continuous operation light fails to light.

 

The control loop appears to try and slew the OCXO

way off frequency.  My best guess is a defective A7

AC amp module.

 

Time to trouble shoot! :- )

 

Comments welcome.
