HI,Derek,
I am sorry,something wrong with my mail which can not received the replay.
I found the answer on user list.
thank you.

Hi Jong,
Marcus Leech and Marco have both offered good advice on testing the frequency
stability of the B210 against outside references. Have you tried either?
Marcus Muller also asked for additional information

Marcus Muller also asked for additional information about your test setup.

The best method for measuring a fundamental parameter like frequency
drift would be to use a signal source of known (and much-superior)
stability, and use something like uhd_fft with the B210 to observe drift
over time (use the peak-hold feature in the FFT display).
The problem with using the end
Dear John,
at this point my recommendation is: Describe your measurement setup in
more detail, and verify it's useful for measuring the clock quality of
the B210, and not the of your CC11xx system. In fact, from what you've
described, I can't really say I understand how this measures the clock
of
HI,all,
Do you have any suggestions about this?
thank you.
