How to open an OCXO?
edpalmer42:
Your TR4172 looks like a nice piece of equipment, although not exactly portable! I love the way they phrase it in the specs - "less than 50 kg". I don't see an external reference input connector. Too bad. You could get either a Rubidium standard or GPSDO to use as a house standard and have various counters, generators, and analyzers all syncronized together and guaranteed accurate to a fraction of a Hertz.
Some months ago I picked up an Advantest R3465 Spectrum Analyzer that was sold as 'not working - for parts only'. It's still a work in progress, but it's now alive and somewhat usable. They seem to build nice equipment, although I wish it was easier to find detailed service manuals. I think I've been spoiled by the old HP manuals.
