Hi
Yes it is a reasonable expectation as long as you don't have a lot of drafts. A
good TCXO can get down to sub 0.1 ppb over that period.
This is why I like ADEV plots in datasheets. I rarely get to see them.
TDEV plots is a nice complement naturally.
Cheers,

Okay, perhaps I should rephrase the question... Is is reasonable to expect a
TCXO to perform at 4e-9 over the FFT window period of about 87 sec? I can only
imagine that the enormous (87 s) averaging period is making my measurements
look so good.
