My time constant is set at 400 seconds which seems to have considerably reduced the size of the frequency excursions compared to the default, and also reduced the large excursions of the DAC voltage. ---------------- I must admit that I've generally tended to leave these as "they come out of the box", perhaps it's time to be a bit more adventurous. None of the five Thunderbolts that I've had on test at one time or another have shown what I would consider very significant short term frequency excursions once settled, just a few parts in 10^-11using a 1 second gate time, if there was any noticeable improvement on that I'd be hitting the unprocessed limits of my test gear anyway. Lady H certainly shows a more dramatic picture though, perhaps another ploy for extending her influence over the unwary and inflicting yet more pain on the innocent:-) regards Nigel GM8PZR _______________________________________________ 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.
