Re: [time-nuts] Datachron 3070
Hi 10 MHz at roughly 10 dbm is a pretty good bet. That’s *if* it uses an external reference and not just something like IRIG. It’s not really clear that they all do have external reference capability (despite the jack).

[time-nuts] Datachron 3070
Has anyone got a manual for one of these by chance? I'd like to feed in an external oscillator but I'd like to know the frequency and amplitude before I go plugging it in at random. Thanks!

Re: [time-nuts] DataChron 3070 Question
I've seen units that do the switch electronically. If there's energy at the external input, the internal source is switched off.
