External Clock Input board for HP/Agilent 332xx series

[vasa1958]

Hi fellows,

Some years ago I made a external clock input board for my HP/Agilent 33220A.

I offer two remaining PCB’s few weeks ago on HP-Agilent-Keysight-equipment groups.io and they immediately gone.

My question is, whether there is any more interest in this or to archive this project?

On my side, to make it cost effective, more than 7 orders are required. The price would be 99USD including the shipping cost to US or Europe and will take about 4-5 weeks to build-up (holiday season coming…).

Design are based on original Agilent 33220-80001 (33220-66503) board and compatible with 332xx series of function / arbitrary waveform generators, but slightly modified.
Input impedance is 50ohm AC coupled, DC isolated from instrument housing and sensitivity of -13 +/-2 dBm. Input level for optimal jitter/phase noise is between 0 and 20dBm. Board is only 10MHz input, no loop back output!

Picture of board installed in my 33220a is attached. New revision will have MCL or Coilcraft 1:1 input isolation transformer.

Hi,

Would you open source your design ?

Could it be made to work on a 33120A ?

@Milan, I would be VERY interested in one of these boards.  I need to lock ALL my gear to my Rubidium clock.

@Artag, there are currently 2 boards for the 33120A on ebay!  I almost jumped out of my chair, but those do NOT work with the 33220A
