thank you for your reply, Eric. we tested the motherboard, source code can be
loaded into FX2, and usrper can be used to configure something. that means
FX2 works well. we use usrp_benchmark_usb to test the board, it doen't work.
something wrong with FPGA. but the clock of FPGA and ADCs are all OK

I think that simply depends on gr-usrp due to the usrp_*.py scripts. It
should work once usrp is up and running, it doesn't h
Hi ,
I am confued by set_auto_tr() and set_enable(). In my opinion
set_auto_tr(True) means that if there is something to transmit( something sent
to the FPGA), the Rx path will be disabled, but if there is nothing sent to the
FPGA, then the Rx path will be always enabled. On the other hand,
Hi，all.
I tried to get rfx900.pcb on the WIKI but failed. Could anyone who have
this pcb file give me a copy?
Thanks!

Hi all,
Has anyone had any luck achieving high throughput (e.g., supporting
interpolation of 8 or 16 with USRP2) from Octave to a GNU Radio flowgraph?
I am trying to stream a signal to my GR flowgraph, and at first I tried
sockets but then realized it was way too slow, and so I moved to pipes but
Hi,
I am unfamiliar with Octave, so I cannot be sure about your particular
scenario, but a potential problem could be internal buffering between
writes... Maybe try flushing the stream more?

I'm assuming the WBX has auto TR switching? Is there any code needed to
enable auto TR switching from C++ after initializing the USRP2 with the
standard usrp2::usrp2::make(interface, mac_addr_str); and then setting
center frequency, decimation, interpolation, and gains?
Thanks for the help.

Hi,
I'm calibrating my USRP setup using a function generator. I remember
seeing that someone else had done this before in the past and written down
a bunch of (input voltage, ADC output) pairs on the web somewhere, but I'm
unable to find it on the wiki even with google site: search.

I guess this is a long shot, but does anyone know of any resources or
documentation on this script? I am working on a custom radar
application for a novel temperature sensor using the usrp and gnu radio
libraries, and it seems that usrp_radar_mono.py could be of help in
getting started.
