HI This one is one of the more significant ones. It shows two Z3810/11/12’s each running against the 5071. It also shows the two running against each other. All are on the 15 MHz output. There are two pretty obvious conclusions:
1) From 0.3 to about 30 seconds the GPSDO’s are better than the 5071. The 5071 is a *great* box, it’s just not as good in this region. 2) Over the region that the 5071 is better than the GPSDO’s, their ADEV does appear (by eyeball) to sum as the square root of the ADEV’s. If number 2 is correct and it applies to the 1 to 10 second region, over much of the range, the GPSDO’s are doing <=1x10^-12. That’s pretty darn good. This one is a low res JPEG. The PDF version was a bit large.
