And this firmware enables the IQP option on my 33522B, too. An unexpected Christmas present from Keysight :)

I just performed the upgrade, both OCXO and firmware. Everything went smoothly as expected.

Thank you Steven!

Merry Christmas!

Glad to hear it is working for you. So far my cheapie surplus OCXO has drifted more then I'd like. In the first 24 hours it drifted about 200 mHz. It has been slowing each day and is behaving better now. The one in my counter is only 20mHz off from when I cal'd it 1.5 years ago - pretty hard to complain about that!

Be careful, you could cross the line to the time-nuts side and never consider anything in frequency again, ever   ;D
