Hi, All,
Kind of confusing about the IF of RFX900.
According to what Eric said (
http://lists.gnu.org/archive/html/discuss-gnuradio/2010-06/msg00113.html
) the RFX boards directly converts UHF to baseband signal. Can it be understood as usrp.tune(f,...) sets the mixer frequency in the RFX board to be f.
Then, why do we need DDC? On the other hand, i
f the
mixer frequency in the RFX board
is set to be f1, while mixer in DDC is set to be f2, where f1+f2=f. How can we calculate/control f1 and f2?
