Hi Jason,

do you remember the threads title or an approximate date?

For TDMA schemes, it would be very nice to know the delay of the AD/DA 
converters (and filters ...), and easiest would to measure the signal from 
the tx port fed back to the same daughterboard via loopback cable to the rx2. 
As far as I understand, this is not possible. (All this requires the 
timestamps of the inband signaling, of course).

Would using a second daughterboards rx require a MIMO/modified daughterboard, 
or is it ok to use two non-MIMO rfx2400 on the same USRP? In my case, 
accuracy of about a few samples would be ok, but there might be other cases 
which require higher accuracy.
