Upgrading Counter 53220A to Option 010 Ultra High-stability OCXO Timebase?

<< < (9/14) > >>

swixo:
Going to try this upgrade today. 
Got my vacuum desolder, RU GPSDO reference for calibration and the part on its way. 
Will update how it goes.

The stock oscillator is absolute crap.  Couple that with a sloppy at best factory calibration,
I am a little disappointed in Keysight here.

swixo:
Well it works!

Swapped out the small TCXO and installed the OCXO.  Cleaned up the solder flux
mess -- it looks super clean.

Self tests pass.  About box says OCXO installed!
System is MUCH More stable after warm-up, which takes about 45 minutes.  No issue there.
Calibrated with RU standard and I am good to go.  Total cost about 320$ which included
Saturday delivery of the part -- AND the Vacuum desolder!

HighVoltage:
What model and type of OCXO did you install?
Pictures?

swixo:
I used this:

Didnt take 'after' pix, sorry.  But the pix earlier in this thread are spot-on.

HighVoltage:
Good to know, that this mouser supplied part works well for the upgrade.
I assume you did not have to change any settings and the instrument detected the new OCXO being installed.
