The first power supply I used couldn't provide enough current for the startup of the heater, so I had to dig out another. After fixing that issue, the first rubidium unit locked very quickly. For initial testing, I'm using a scope, triggered on my HP Z3801A. After several minutes of warm up (I didn't time it), I detect no drift in the rubidium's 10 MHz at all. I do see a bit of jitter and some "bumps" on the peaks of the sine wave.
I'll cook this one for a while and then try unit number two. Joe Gray W5JG _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
