FYI, I've run this for the past 24 hours (on the production app, not the
test script) and haven't seen any segfaults.

Hi everyone,
I am working with uhd_fft.py and have made some changes and gotten the data
to display as desired using fft_sink_c. However, in addition of displaying
the data, I would like to save the data to either a single file (append the
incoming messages) or to a series of files. Is there a way
Hi guys,
Currently, I'm using GNUraido with UHD to do some research about SNR and
BER. To estimate the SNR, I use the metric of a paper named Robust
Frequency and Timing Synchonization for OFDM," IEEE Trans. Communications,
vol. 45, no. 12, 1997, which has been implemented in the ofdm_sync_pn.py

Try dropping the sample rate even lower--1Msps?
Is it perhaps
possible that the device is plugged in to a USB-1.1 port, rather than a
USB-2.0 port?

Like Josh said, one or two "U"s isn't a big deal, but is it
underflowing constantly? That would be strange.
Are you looking at the output on an oscilloscope?

hi nick,
thanks for your reply
i tried the same command line arguments you gave me but the problem that there
is always an under run error even if i change the args i tried several
combinations but none of them worked
any suggestions about that underrun problem
thanks,

I would like to say that I just received a new N210 and am very happy with
the quality and performance of the device. I have started to familiarize
myself with the included utilities and have run the uhd_cal_* routines.
My question is does repeated runs of the calibration increase the

Are you using tx_waveforms? How are you measuring the received signal? Try this:
./tx_waveforms --ampl=0.5 --rate=4e6 --gain=20
--wave-type=SINE--wave-freq=10e3 --freq=1.1e6
This should produce a tone at 1.11MHz on the TX_A output of the BasicTX.
If you don't see the desired tone, please cut and pa
Hi all,
I use a TVRX daughterboard to acquire VHF signals. I believe (but I may be
mistaken) that the TVRX daughterboard downconverts RF signals to a baseband
of 6MHz bandwidth before going to the ADC. The function usrp_rx_cfile
(which I use to acquire signals) has a minimum decimation factor of 8
hi all,
i am using usrp1 and a basic tx when i run any uhd example that transmits data
i see the meta data going out from the fx2 to the fpga but it never goes to
the codec so no signal is generated
any help is appreciated

dear all,
i am suffering an under run error when running the tx_waveforms.cpp example i
