So, I got a reasonable deal on a SR620 ho ho. Know your dealer. The ocxo is out of tolerance. All self tests pass with flying colors, autocal works as well. So the best parts are OK. Does anyone: 1) have a spare Isotemp OCXO36-53 10.000 MHz p/n 6-00051? 2) know the specs, ie the input voltage/current and the control voltage span and direction? pinout? I have some Morion mv-89's and could easily cobble one in if it will work. Apparently a correct oscillator must be in place to use an external source, if I read the manual right.
3) do we have a source for the schematics for the SR 620? The FTS 4060 is up, pumpin' and firmly locked. At least for now. That dealer was not lyin' Much thanks to all of you.
