[Discuss-gnuradio] Multi-channel I/Q buffer format...

I'm getting some strange behavior when I use two DBSRX boards with my USRP.  I just wanted to vet some of my assumptions as I'm debugging.  I'm assuming that the data comes across the USB bus as follows

I_A/Q_A/I_B/Q_B/I_A/Q_A/

Is that correct?  i.e. do we get I/Q of one board followed by I/Q of the other board?  And they come across as 2-byte samples for each I and 2-byte samples for each Q?

So...

I_A_16bits/Q_A_16bits/I_B_16bits/Q_B_16bits/... and so on?

Again, I'm just trying to make sure I don't waste time debugging elsewhere.  Thanks

Jared
