Thanks a lot, guys. I got it.
Best Regards,

I think I can clarify things a bit. The WBX and SBX default to what is
called direct conversion or homodyne mixing (see
http://en.wikipedia.org/wiki/Direct-conversion_receiver). I'm not sure
about this, but also if you offset the LO as per Nick's link, you
effectively make those boards do superhete
Broadcast FM has a channel bandwidth of 150 kHz, so a sampling rate of 200 or
256 ksps should work fine. Don't confuse the sampling rate of the zero-IF data
with the sampling rate of the front-end, which is 64 msps (USRP1) or 100 msps
(USRP2).
The UHD API tends to hide this. In the old classic
Hi Nick,
Thanks for your reply.
But I am not sure whether I understand what you said. My understanding is
that the WBX converts RF signal into baseband signal directly, while for
TVRX2, the RF signal is converted into low IF signal firstly by TVRX2 and
then converted into basebad signal by USRP's
Jamie,
WBX is a direct-conversion receiver, meaning there is no IF: it is a
quadrature receiver where the LO frequency is equal to the RF frequency.
TVRX2 is a low-IF receiver using a 12.5MHz IF.
Both daughterboards can be treated as zero-IF direct conversion receivers
for tuning purposes, as th
Hi all,
As far as I know the maximum sampling rate for USRP N210 is 25M sps. To
receive signal with high frequency, such as 300 MHz to 2.2 GH, the RF front
end converts the RF into IF, so the ADC can sample the IF signal. My
question is what the IF value is for daughter-board WBX? Where can I
