Hi all,
I would like to do the spectrum sensing for the whole 2.4G ISM band ( 2.4
-2.4835GHz ) to figure out where the spectrum holes are. I would like to know
if it is possible to sense the whole band,2.4-2.4835GHz, through the
USRP? However, the ADC can only support 64Msamples/sec. How ca

I can find schematics for flex2400 receiver and transmitter, but none for
the flex1800. So far I have been guessing that they are pretty similar but
it would be nice t

Hi,
How can we get/tap a base band analog signal (I and Q) from the FLEX
900 daughter board. Are there any pins on the board from which the
signal can be taken out directly.
No easy way, but you could tap into the signals by soldering little
wires to the board.

Hi there,
Does the RFX900 have an AGC algorithm that it automatically applies? Or
does the host machine have to implement an algorithm via the
write_aux_dac command?
As shipped, the RFX-series does gain control via software using the
set_gain() command, which uses w

Tnx Martin, that's what I'm looking for.

Hi,
We just received 2 USRP mother boards, and 4 RFX2400 boards with 4 vert
antennas, I have installed them and connected with two separate PCs (os
ubuntu 8.04). *I installed all the required packages*
I did benchmark_tx and rx and siggen.py and got same results as
explained in given documents on

Hi Hansi,

While trying to pinpoint why my setup with my DBSRX did not work
with the GPS-SDR software (http://www.gps-sdr.com)I came across
some funny results. I was using usrp_fft to check the spectrum
in the neigbourghood of the L1 freq when I saw some spikes.
Just to make sure, I removed the antenna, tu
