HP 5386A frequency counter teardown

<< < (3/3)

0culus:
Really nice and clean too! Good catch!  :-+

I have a 5335A with the OXCO option (and I think pretty much every other option as well; even the DC voltmeter option) that sits on top of my 5350B microwave counter, and provides the timebase for it. I recently also replaced my shitty Chinese DDS with a 3325B from the same seller I got the counters from, which also has an OCXO, but it doesn't have an internal connection to it, so I have a jumper.

Seeing as how this is a teardown thread, here's some pictures of the 3GHz prescaler.

rhb:
Curiously, all my HP gear has the OXCO option except my Keysight 33622A.  But I plan to connect everything to a GPSDO, so I don't think it matters much.  Even without the OXCO the 33622A is very stable.  But I haven't put together a test and verification plan for my bench yet.

Radiorandy:
I've been trying to find the guy in Poland that has the Option 4 clone OXCO. Doesn't show up on Ebay. Anyone have a link or contact info?
Thanks

Randy
