Hello, Time-Nutters-- Is there any possibility that opening and closing the Lady Heather display inflicts some sort of temporary disturbance to the T-bolt it is monitoring?
If I run the Lady Heather display on my Dell Dimension 9200 desktop screen and let it run undisturbed for 8 or 10 hours, it tells me that my T-bolt has settled down nicely; PPS staying within +/- 2ns to 4ns and Osc never straying outside of roughly +0.01ppb to -0.01ppb. The PPS OADEV gets down to the 4e-13 category and the OSC OADEV to around the 3e-13 category. The green DAC graph stays well centered within one division over or under (@ 100uV/div) and the violet PPS graph also stays well centered within +/- one division (100uV/div). The yellow temp line stays centered inside one division. Everything looks great.... right...?? As long as I do not minimize or close and then re-open the LH display, this situation will continue for many hours. HOWEVER-- if I close the LH display and open it back up shortly thereafter, all my T-bolt running parameters start fluctuating wildly and going off-scale. Even the yellow temp line goes off scale and PPS OADEV and OSC OADEV both drop back to a high e-12. It takes about 90 minutes for everything to settle back down, after which everything runs tightly for many hours until the next time I minimize or close and re-open the LH display. If this is just a coincidence, it sure has happened with consistent regularity over the last week or so since I first noticed this behavior. Is this just a coincidence? Has anyone else noticed anything like this? I can send anyone a before and after screen capture of what I am describing.
