Dan,
I have a solution that I have been using for a while. I have attached the
relevant files and a working example. You will need to put all the files except
the .grc file

I haven't used GNURadio companion before, but what you need to do is the
following:
Set the mux to (0xf1f0f1f0). This will connect ADC0 (which is the first ADC on
side A) to the I inpu
Hi all,
I am having trouble using GNURadio companion and getting the wav file sink to
work for me.
I am interested in recording from a USRP with an LFRX daughtercard. I am
simply trying to record from Side A, on the RXA channel.
To do this, I am using the following blocks in order from left t
Hi all,
I am looking to simultaneously record two real signals (not with IQ) using a
single LFRX daughtercard.
How can I do this with GNURadio companion? I have spent a while looking at the
USRP Source and Dual USRP Source blocks and could not figure out.
I am looking to record from Side A wi
I'm hoping to record signals from an LFRX board (or two) using a python script
similar to
usrp_rx_cfile.py
Does anyone know if there are any examples of code that is similar and can
simulaneously record from two channels and save to separate files?
I don't want to run two instances of python sc
Hi,
I am slightly confused on the USRP configuration. The spec sheet says there
are 4 input and 4 output channels. Assuming you use two LFTX, and two LFRX
daughter cards, it makes sense that you have 4 input and 4 output channels
since each daughtercard has a jack labelled A or B.
For IQ sam
all what I got in terms of counts for saturation.
Thanks,
Dan

Hi Da
Hi I've done some tests over the last couple of months with a USRP
and a LFRX daughtercard.
I have been using the usrp_cfile_rx.py script with decimation
of 32 (2 MHz sampling rate).
I did some calibrations using a waveform generator that has a 50 ohm
impedance output. I set the waveform gener
Hi,
I'm using the USRP and LFRX and LFTX daughtercards for an underwater acoustics
project.
I am confused on how the IQ (complex) and real sampling works with the USRP (I
read a couple of papers and im still lost). If I wish to use real sampling and
I install two LFRX and two LFTX boards
Hi,
I've been using a waveform driver with known amplitude to calibrate the counts
reading on the USRP/LFRX when I use the usrp_cfile_rx.py script file with
decimation of 32 (2 MHz sampling).
I performed the calibration using 0dB gain on the USRP, and 10 dB gain for
various frequencies from
Hi,
I'm trying to figure out an impedance problem with my USRP/LFRX system. I am
using the LFRX daughtercard to measure background noise from a hydrophone
(underwater microphone). I am using a +40dB gain preamplifier to amplify the
signal from the hydrophone and then I feed it into the LFRX
Hello,
I'm having a ton of trouble with the USRP/LFRX daughterboard setup. I am
trying to calibrate the counts that are stored as integers when I use the
usrp_rx_cfile.py script.
I am using an HP waveform driver with 50 ohm output impedance to feed single
frequency sinewaves to the LFRX cha
