Hello Ze Zhang:
First, there is a dedeicated mailing list for USRP-specific questions: USRP-users.
https://kb.ettus.com/Mailing_Lists
"the information mentioned that the common structure for all USRPs is the IF bandpass sampling structure," -> where did you find this information? This is, in general, not true. USRP N200/N210s, especially, usually default to zero-IF (direct conversion) mode
(not always, though).
In case of the USRP N200s/N210s, daughterboards implement the RF/IF (if exists) stages of the transceivers and the motherboards implement the baseband and the digital stages of the transceivers. The daughterboards often do not have any IF stages, and directly
convert the signal to the baseband. The motherboards CAN implement a low-frequency IF stage by digitally shifting the baseband signals before the decimation stage. This is optional, and not used by default.
Regards,
Kyeong Su Shin
