Dear all,
I have modified the file usrp_basics.cc to make the soft prints some
information when running.
When I recompile gnuradio, these modifications are not taken into
account (no information is printed). I have tried several tricks such
as:
Make uninstall
Make clean
before recompiling
Thanks.
And what is the minimal level of signal that can be detected by the USRP (with
the TVRX) ?
Thanks for your answer

Dear all,
What is the TVRX front end sensitivity?
Thanks and best regards,

Dear Aadil and dear all,
Thank you for your answer.
I work on the opportunist access to UHF bands and I try to detect the channels
where a DVB-T (HDTV ?) signal is present (thanks to some correlation methods).
I then compare the power of the received signal in the bands where I have
Dear all,
I would like to compare two signals in two distinct bands of frequencies
(energy in particular) with the TVRX module.
Is there an AGC in the USRP/TVRX module ? If yes, how can I get its
value ?
How the programmable gain (set with the command set_gain of the sub
device) impacts on
Dear all,
I have not been able to have the scope work with my USRP and my TV front
end.
When I launch the script, the program seems to be freeze, but I can stop
it with Ctrl+C. And the FFT works fine.
I have a USRP board Rev4.5 and the TV Rx v3 front end. I used a decim
rate of 8, a central
Dear all,
I have been trying to compile the block gr-howto-write-a-block-3.1.0 (I
am using Cygwin).
I have copied the boostrap script from the gnuradio dir into the
gr-howto-write-a-block-3.1.0 dir. When I launch the script, I get the
following error:
Dear all,
According the USRP v4 description:

http://www.ettus.com/downloads/usrp_v4.pdf
the usrp is able to process signals up to 16MHz.
As the USB port is limited to 60MB/s, and if the samples are coded on 32
bits (16 for Q and 16 for I), the
Dear all,
As anyone been able to process OFDM signals with the USRP?
In particular, I have seen that many works have been started to develop
a HDTV decoder with the USRP. Have you been able to decode the OFDM
symbols (and decode the HDTV signals) ?
Thanks,
Best regards,
Pierre
