I recently acquired a couple of FTS 4100/S12 cesium frequency standard modules. These are, I've been told, basically the guts of a 4050 (and maybe 4060?) commercial standard repackaged for military "fly-away" use. They run from 22-30 volts and have a couple of switches and a meter jack, but no front panel. I have two units that both seem to lock up, though both have minor glitches, and a third once worked but recently stopped locking; I'm trying to fix that one for a University group.
I have some very basic operations-level documentation for the 4100, but nothing that helps with troubleshooting or repair. Does anyone here have a service manual that covers the 4100, or much more likely, the "CFS" package of the 4050 or 4060? A scanned copy would do the trick very nicely. Thanks!
