The tune delay timing parameter passed to bin_statistics is
Working to understand sink block bin_statistics_f. Examining the User
Manual, the sourcecode gr_bin_statistics_f.cc and related includes, and
hacking qa_bin_statistics.py, this is my current understanding:
1. bin_statistics determines max values of vectors with length vlen over a
number of samples

Hi,
I am looking at the usrp_server code in the trunk and have the following
question.
Is there any difference between a tx/rx "port" and a "channel"?
I see that the usrp_server is always initialized with N_PORTS=4 tx and
N_PORTS=4 rx ports (total of 8 + one control port), but later on, we

The usrp2_fft python code was recently changed to use that adc_rate() call,
although the actual implementation returns the value to the input pointer
parameter.
Just change that line in usrp2_fft back to what it was so you can at least test
it:
From:
input_rate = self.u.adc_rate() / s

I tried to run usrp2_fft.py to test my USRP2 board and I got the following
error.

Hey slimchao,
Thanks for the reply! I tried gr.file_sink().
It writes something in a txt file, but when I open it it is not in
readable format.
Is there something that I can do to make it a readable .txt format for
the MAt lab, where every sampled value is written as float value on a
new l

The directions are the same for Matlab.

Hey all,
I want to store the signal I recieve from my USRP+XVR2450 in a text file,
in 2 columns(1st clumn time and 2nd column I and Q voltage levels from
USRP at each sampling time).
So, how can I do this in the Python? I want to do this because I prefer to
do the signal processing on the baseba
Hey Paul,
Ya! you are correct, the isolation is a problem.But what is curious is when
i operate the transmitter and reciever simultaneously,the signal level of
the reciver decreases too much(cancels out) . If some of the signal from the
transmitter antenna is also recived by the reciver antenna,
Hallo Everyone,
I have generated some samples of a sinesoid from Matlab and want to convert
it to a binary file and use it as a source signal to the LFTX daughterboard.
Can you tell me how i do to convert it?
Thanks a lot,
Chao
