Hi,I read in the Dawei Shen tutorial 4 (The USRP board) that the multilple RX channels must be the same data rate and the same applies for the TX channels. Looking at the top level module, usrp_std.v, more preceisely the TX side for example, it seems that both tx_chain modules share the interp_rate
Michael,
thank you for doing an excellent piece of detective work to get to the
source of this issue! Well done! I'll be at ND for "The Game" next
weekend, and if you happen to go there too, I'd like to buy you a hot dog!
I have another surprising data point to add to this whole thing: I just
Hello,
I’m a newbie and I installed Gnu Radio with
svn. But I read a tutorial that there is a document generated with Doxygen
about the USRP in /usr/local/share/doc/usrp-xx…./html.
I search all in my filesystem and I did not find any
html document for the USRP. I tried to generated
Well, all I can think of is using the basic rx daugtherboard along with
usrp_wfm_rcv.py and tuning to some local FM stations, or using the scope,
but it sounds like you've already done that pretty much. Make sure the gain
on the scope is set to about mid-point for the specific daughterboard being
Well, I've never used the TX boards before, but looking through the files I
found fm_tx.py, which makes narrow band fm. You may have to use
usrp_nbfm_rcv.py (or whatever it's called) to pick it up, but now I'm just
guessing.

If you are using the Basic RX board,
Anyway, installation, make check, and the ./test_standard_?x scripts
work fine (the LED behaves as expected and the benchmarks seem
reasonable), however I get nothing when running the usrp_oscope or
usrp_wfm_rcv scripts as directed in the instructions. Both dial tone
scripts work fine, by t
Fair enough; I figured since my officemate's pocket CD player could pick
up FM radio the big ole' antenna ought to be able to.
Is there a script to make a custom FM station using a BasicTX board (I
have another USRP if necessary) to get around that problem?

Hi all,
I'm just beginning grad school and trying to get my USRP board up and
running so I can start playing. I've tested our equipment on two
different machines now; one an older box running FC4, 512MB ram, with an
Intel(R) Celeron(R) CPU 2.40GHz. I've also tried one on a newer laptop

All,
I would like to modify the code for mainloop in order to make usrp_fft.py
exit after an interval of time without having to manually close the window.
I have stepped through the debugger a lot, but to no avail. I profress
ignorance. Any advice on how to accomplish this?
Thanks,

Ok. Thanks for the quick reply.I was also wondering about the following. One of the input to the usrp_std module is SDI. From my understading, a serial address and serial data is sent through that input in order to control registers inside the FPGA. What I don't know is the origin of the input. It
