We usually don't use the word residual for this. When you compare a watch with
a maser, or any DUT time against REF time, you get a quantity like: phase
difference, or som
Hi
On a normal GPSDO holdover spec, you are concerned with the maximum
time error over a specified period. Generally it’s going to be a 24 hour
holdover,
but it can be longer or shorter depending on the application. The good old CDMA
spec got out into the 10 to 11 us range at 24 hours. Various OE
I looked at AN1279 and other HP Smartclock documents that were written for
the telco holdover specs, and they always put a zero axis on the frequency
offset, but I was surprised that for example fig A4 of AN1279 seems to be
suppressing the zero axis for the time error. So they seemed to be
unconcer

Hi
I think your “quest” to find the terms as they relate to motion is a pretty good
example of just how unusual these terms are. Once you go past displacement,
they are hardly common vocabulary. My guess is that nobody has ever come
up with terms in the time domain that have made it into the
I think that should be "absity" (s not c)

Now if I now plot the cumulative sum (think integral) of the residual,
that's going to give me an ov
