Thnx Marcus..u mean that if i change the sample rate of USRP sink
block in the properties dialog box then the bandwidth will be equal to
the changed sample rate??

I've slowly gathered the courage to try out the B210 devices. I was
impressed by the fact that I could get 50 MHz of bandwidth out of it.
However, I immediately ran into problems with absolute timing.
I've been using the B210 for mimo with USRP N200 devices for testing. The
N200 devices all nicely
Hi Ali,
the Nyquist bandwidth of a complex signal is equal to its sample rate.
You can set the sample rate of your usrp_sink during flowgraph
construction in the properties dialog,
using stream tags, using asynchronous messages or simple method calls:

Hi ,
Can anyone kindly tell that how i can vary the bandwidth of my
transmitted signal in GRC??I am using B210 which has a instantaneous
bandwidth of 56MHz..

That is exactly what the file sink does, see the proposed solution I've
discussed in this thread.

thank u sir,
now, i just want to export the complex stream that goes into the sink, is
that possible? whats the format of the that complex stream?
cuz, in the my group design, USRP is in charge of signal collection, the
rest signal processing(FFT) work will pass to a FPGA.

Hi Yang,
the Power of the FFT is only calculated inside the graphical sink, the
connection between the USRP source and the graphical sink represents a
complex sample stream.
I'm still not quite understanding what you really want the USRP to do,
would you mind explaining that again?
Best regards,

Thank you, Nick, for clarification!
Yes, I was kind of messing that up.
I've done little PMT work -- is there a convenient way to "reinterpret"
the payload of any PMT as u8v/blob?
Greetings,
Marcus

Hello,
I made an attempt to compile the actual git master branch with MSVC2010
under win 7.
There some issues which I want list as follows. (Sorry for some german
compiler
messages, but I think there are self explanatory.)
It would be fine if gnuradio can also be builded by MSVC compiler in th

We have our own blocks for processing on the FPGA. They handle the
command & control of the FPGA and the transport.
