Hewlett-Packard 3302A Trigger/Phase Lock Plug-in for 3300A
« on: September 17, 2022, 12:16:19 pm »
IT IS DRIVING ME NUTS..
no one ever shared a schematic for this module online ?
the phaselock part of it is not working,
previous owner messed a round in it, many funny solderings, and dots from scope probes
reveal he spend a long time trying to figure this out..

anyone got a schematic ?
