Hi Marcus,
Thanks for the quick comments. Yes, I totally agree that using full
duplex with RX2 and TX/RX would be the ideal way to go, and as you say
I can easily ignore and synchronize with my own transmissions. The
problem is that I am required to use a single antenna, so I have to do
a half duplex solution with all its warts and synchronization
problems.
As for the switching time, I do not care if the switches (or the FPGA)
introduce deterministic delays, I can cope with that.
You mention that the state machine is set up in the daughter card
setup driver. Is this the file in
"host/lib/usrp/dboard/db_sbx_common.cpp" for the SBX board? Is this
code used for USRP2 and not only for USRP1?
Best,
Miklos
Yes, as far as I know. Josh could probably comment in more detail, but
he's at a conference today.
I wouldn't recommend mucking about too much with the ATR code, since I
think it's possible to end up in a "TX connected to RX" state if you're
not careful.
