[time-nuts] Re: HP 5065A, no 2nd harmonic.

[Jared Cabot]

Hi,

The electrical tune (fine control knob) is set to midrange now, at the 250 setting. The mechanical tune (the one in the OCXO itself) is maxed to its limit and I can't raise it further.

My 5335A has the OCXO option, so if it is compatible, I might be able to do a swicharoo into the 5065A to see if it comes alive, that will tell me for sure that the 5065A OCXO is being naughty.


Thanks!
Jared
