Hello, I use TimeLab and the HP5370B and a Prologix GPIB interface. After making several 10 Hr runs with the same oscillator I noticed something
When laying the successive runs on top of each other there are little blips and bumps that line up perfectly on top of each other. For example each run has a small blip at 10 seconds in, and a rise from 50 seconds to 150 seconds This was happening when I was using the NI PCM-CIA interface as well. If time is the X axis and variation of frequency is the y axis , how can something repeatedly happen at 2 points in time. I am sampling at 1 S per sec and 10 Hours duration in these particular traces. Can I have some sort of cabling issue? Or is there something in ADEV algorithm that forces this to happen.?
