Hi guys,
I have two questions about the USRP's architecture that I have been unable to
answer from looking around.
1) I understand that when a daughter board is tuned for Rx, the exact frequency
is not always possible, so the receiver tunes to the nearest possible frequency
and the 'requested' frequency is the sythesized in the DDC. Coming from a
conventional RF background, I don't understand why the receivers can only tune
to specific frequencies - is it something like resolution in the digital
control of the VCO's in the receiver? (Just my guess)
2) What is the raw bandwidth of the output of a daughterboard? The USRP2 can
process a 25MHz wide chunk so I'm guessing its at least as big as that.
Cheers,
Matt
