Hi,
Well, there is differences in level, there is tables for it, so while on
the large scale they are close, they are not the same.
Vernotte have a table of it in one of the PVAR articles for instance.
Cheers,

Hi
The intended purpose of MDEV was to supply a plot that looked the same as an
ADEV
plot *except* for separating flicker phase. To the extent they succeeded, you
can use
the same plot on either one. (and as long as flicker phase is not an issue). To
the extent
they failed, you are stuck.

TimeLab can show "mask" overlays on various plots. It comes with a set of
ADEV masks for cesium clocks, derived from the manufacturer's
specifications for those clocks.
Those masks don't show up on MDEV plots, because the manufacturers don't
provide MDEV specs.
For the mathematicians out there: is there a way to convert ADEV specs into
equivalent MDEV specs?
If not, does anyone have good measured MDEV data on any of the popular
cesium clocks?
The slopes of ADEV for the different noises can be converted to slopes in MDEV.
It is the separation of white phase modulation and flicker phase modulation
that doesn't go very well with ADEV, but works in MDEV, but if you ignore the
flicker then you should be able to translate without too much difficulty.
Good luck!

Magnus
