Hi Hans-Georg,
Maybe it is better to refer to this as the inverse of 20,48 GHz, since
that is the virtual clock rate of the interpolated coarse-clock.
Considering that it is 2048 * 10 MHz, it is not hard to imagine that a
coarse clock of say 80 MHz is then interpolated by 256 to achieve that,
Hi Hans-Georg,
You're MDEV slope is not that of white noise, but that of a (correlated)
systematic damping. You have 1/tau^2 rather than expected 1/tau^1.5.
Also, your levels are way off. This steeper slope for systematics is not
widely documented by the way, but direct consequence of the
Sorry, this was completely nonsense .. i correct the resolution factor
and forgot the "e" so i get 4.88281248-11 as factor and scaled
the timelab plots with it. My interpretation is just as stupid.
The correct Factor is 4.88281248e-11.

Hi Hans-Georg,
Does the E1740A also has the STP2945 as timing reference?
First of all, you have nice illustrations of the white phase modulation
noise slopes, of tau^1.5 as expected in the MDEV. Trouble is, it's not
pure WPM noise, but a mixture of the noise and the quantization effect.
So,
