Hi Chris, Sorry for a delayed reply. The OSA 3210 is one of the only cesium standards I don't have in the "museum". I've seen one or two on eBay over the past decade but not in worthwhile condition. I hope you can get yours working. If not, let me know...
The good news is that I have an original Oscilloquartz 3200 cesium manual. Today I scanned the first part of it for you. See: http://www.leapsecond.com/museum/osa3200/ If this is helpful to your efforts, I'll try to scan the schematics as well. The manual is an inch thick. I don't know the model differences. I've seen 3000, 3020 and 3200, 3210, 3230, 3235 mentioned on the web. Maybe 3120. I'm also not clear about the differences in series-3000 vs. series-3100 vs. series 3200. If anyone knows, please post details.
