Hi, I was looking at the UsrpTxModifications page in wiki, I want to
understand how the Tx goes.
my question is what is the spi_bus that goes into the data block and come out
of the command block, is it internal in the FPGA? looking at the
UsrpRfxDiagrams in the first digram I see the signal come out of the FPGA as I
and Q, But looking into the data sheet of the AD9862 there is only one input
as the Tx data and from there it become as I and Q signals. Is there any
detailed diagram of the 'inside' FPGA, I have know two different diagram one
on the wiki page the other is writing by Oussama Sekkat( I have it as pdf),
which one is the write one. Another thing I want to send two signals from two
tx boards but phase shifted from each other, is there a way to control the
phase of the Tx signal?Thank you,Anmar
