Yes

Yes, and I have red about the Tx moeds and the clock timing.

well, today I tried without each time powering on the usrp, and I get
repeatable results, but when I load different code like am_tx then there
will be a small phase shift, resetting the USRP I get the normal
results. I made some pictures :).

I have two basic Tx daughterboards, so each one use different AD9862. I
have a question the 2 AD9862 they both get there clock in from the usrp
motherboard, and that is the same clock?
