Probe R201 on all 4 WBX boards with an oscilloscope while running. One
side of the resistor is ground and the other side is the reference
clock. They should all be around the same amplitude, and have the exact
same frequency and phase.

Hi
Hi all-
I have a multi-usrp setup with 2 USRP 1s and 4 WBX daughtercards. I have
performed the clock synching described here:

I'm doing 4-channel receive, using a power splitter to send the same CW
signal into all 4 d'cards, and tuning them all identic
