> BTW: Do you know the cause of the oscillations in the 5065 vs BVA plot?
The ADEV wiggles aren't visible with normal tau 1 s measurements. But since the TimePod can go down to tau 1 ms, when I first measure a standard I like to run at that resolution so effects like this show up. Once that's done, 1 ms resolution is overkill. In this case it appears to be power supply noise. Attached are the ADEV, PN, and TDEV plots. The spur at 120 Hz is massive; there's also a bit at 240 Hz; almost nothing at 60 Hz. When integrated these cause the bumps you see in the ADEV plot. It's best seen as a bump at ~4 ms in the TDEV plot. Note the cute little spur at 137 Hz. Not sure what causes the one at ~3630 Hz. /tvb
