I have a couple of HP 5370s with the beaglebone brain transplant. They come with a nice 10811 that has a little adjustment screw.
Testing against a Thunderbolt or KS-24361 the 5370 is off by less than 1Hz. I know the traditional method would be to adjust the crystal slowly and make careful measurements, but since I have a fancy computer in there, I wonder if I could just adjust the frequency in software. 64-bit floating point numbers should have sufficient accuracy. All reported measurments would be corrected for the actual reference frequency. Basically, I'd have a 10000000.226 Hz internal reference. In fact, could I connect the beaglebone to a a GPS 1 pps source and make this a GPS-disciplined-software-corrected oscillator. So my question is is this a known technique? The discipline feedback circuit seems a little different, I'd adjusting for drift and offset, but not the gain of control-oscillator linkage. _______________________________________________ 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.
