Hi all,
I learn from some document that usrp have take a timestamp in nanosecond
with the data package. Can anyone tell me more detail about that? Since I
have not receive usrp board I can not do the experiment to confirm it.
Thanks.

hi all,
I want to use the read_aux_adc method to get the RSSI,After reading
the code, I think the argument 1,0 should be right.
But the result is strange. when there is no sender , the value
returned is always 12. While there is a sender and the distance
between sender and receiver is less than 1m
Hi all,
At first, I use the benchmark_tx to send with usrp-a. After sending is
finished ,I use the benchmark_rx to receive on the same usrp and there are
another sender which is usrp-b.But I can't receive anything. The
usrp_source_c gives nothing.
If I reload the firmware of usrp-a, everything is

Yes, I would expect that as well. H

Hi all
I had a problem with tunnel.py, but changing threshold from 30dB to 50dB it was
solved, now I'm reading receive_path.py in carrier sensing blocks are defined
alpha=0.001 and thres=30 for use with gr.probe_avg_mag_sqrd_cf, please can
somebody tell me what is alpha value and why is set to
Hi everyone,
I know this is a little out of context, but has anyone done any power
measurement on US TV bands either with USRP1 or USRP2? The thing is I was
trying to compare my own measurements with TV fool data but I couldn't find
any relevance among them. For instance, those channels which are

No further development. You can't buy a new PS3 that will run Linux.

Hi all,
I plan to use the USRP to run a feedback controller. The basic idea is to read
in a feedback signal over three input channels (two LFRX daughter boards),
process them to generate control signals that are output over three DACs (using
two LFTX daughter boards). All of the processing will

Hi Raveh,
I advise you to check first the tutorial:
http://gnuradio.org/redmine/wiki/gnuradio/TutorialsWritePythonApplications
Then there are plenty of examples in gnuradio/gnuradio-examples.
