Brian, The support board part number indicates that it was used in a model HP 5328A or B counter. I find that some versions of that model used a 05328-60027 board. Maybe you misread the part number? Anyway, There are a number of complete manuals for the 5328A & B counters on the web, available for free download. Here are a few links: http://bama.edebris.com/manuals/ http://www.ebaman.com/index.php/remository/ELECTRONICS/Test-Equipment/ http://www.ko4bb.com/manuals/ http://www.keysight.com/main/facet.jspx?t=79910.g.3&cc=US&lc=eng&sm=g&no=0
A check into the Federal Supply System indicates that that model oscillator was an alternate for the venerable 10544 and 10811 oscillators, so pinouts should be the same as those models.

The oscillator itself is a Piezo Systems 2810007-1 and it is plugged into, what appears to be, a buffer board, HP part number D23703F 05328-20027. Three questions: 1. Does anyone have the pinout for the oscillator? 2. Does anyone have the pinout for the buffer board? 3. Does anyone have a 15-pin card-edge connector for the buffer board? My plan is to turn it into a GPSDO. -- Brian Lloyd 706 Flightline Spring Branch, TX 78070 [email protected] +1.210.802-8FLY (1.210.802-8359) _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to http://lists.febo.com/mailman/listinfo/time-nuts_lists.febo.com and follow the instructions there.
