All data on the Oscillatek parts is long gone …. even to the person who ran the company ( = me ) …. Simple answer: Hook up a power supply and feed the tune input. See what you get. On a part that is many decades old. That’s going to be far better data than anything from “way back when”.
Thanks Bob! Just did some experiments. Doing a Lissajous against a GPSDO, it is "real close" with about -100mV on the CV input (about 20 min. warm-up). The freq is inversely related to the CV voltage. Across a range of -12V to +12V, the freq varies from about +10 Hz to -25 Hz. I'm planning to hook it up as an external reference for an HP59309A clock. Now my thought is to put a Schottky diode in the ground leg of the oscillator (to raise the ground reference slightly), then use a trim-pot on the CV input to fine-tune it. Meanwhile, I'll build a self-contained GPIB controller to make setting the clock more convenient. And I've got some other GPIB-capable instruments that I can hook it up to.
