Allan Deviation in E8257

Hi all,

I have performed an allan deviation measurement using E8257 at 24GHz, and a very stable 10 MHz external reference (H-maser).

The curve follows a thau-1 trend in the short term region, but becomes flat and relatively high between thau 100 and 100sec.

I don't find any long term stability specs (with external reference) within the E8257 documentation.

Can anyone help me on this? Is the E8257 stable enough to do this sort of tests?

Thanks in advance.
