Get a waveform of usrp clock 10~64MHz using file_sink

Hi,

is it possible to save a waveform of usrp clock using file_sink?
I want to save the usrp clock signal like other transmit and receive
signals, but due to lack of knowledge, have no idea.
Thank you.

James,

You want to store the sample clock waveform?

This is relatively confusing.

I doubt you can do this. It would look like a 64MHz square wave. You
could feed in a reference wave (perhaps from a signal generator or other
accurate clock) and look at it’s deviations from the reference freq to
deduce what the 64MHz clock is doing.

Maybe if you had 2 USRPs you could feed the clock of one into the RX of
the second.
