Hi Marcus,
I followed all of your step-by-step instructions and after installation, the
uhd_find_devices command returns:

Dear all!
I am trying to transmit a complex signal with the USRP2+WBX system.
First I tried transmitting from file, an 8MHz band recorded with the USRP2,
by connecting the "from file" block to the USRP2 transmitter, with and
appropriate interpolation.
When visualizing the output on a spectrum ana
NIck,
What do you mean by "mix one sideband up and the other down"?
How would that go?
Thanks
Vlad.

Per,
At the moment we don't have a MIMO cable, so we're looking for alternative
solutions until one makes its way to our lab :)
Thank you for your suggestion though, it is much appreciated.
All the best,
Vlad.

resulting signal band still occupies 16MHz.
Any ideas?
Your help is really appreciated,
Vlad.

I am interested in this 2 USRPs approach since I don't have the experience
and the knowledge to start messing about inside the FPGA firmware code and
have an extra USRP2.
How would this go?
I tried looking up some info about this topic but currently gnuradio.com
seems to be down. I've read some bi
What would be the best way to work with a 32 MHz band resulting from USRP2?
I guess, since the minimum decimation rate is 4 (resulting in a 25 MHz
signal band), some kind of interpolation will be required or maybe
resampling?!
Any ideas on how to proceed?
Thanks in advance!
Vlad.

Thanks Marcus.
You did manage to tie up several loose ends, and I really appreciate it!
All the best.

Dear all,
I would like to receive as many suggestions as possible on how to accurately
measure bandpower with a USRP2 + WBX setup.
I know I should use a block that does the square magnitude (FFT squared) and
sum the resulting coefficients but after this I don't really know what the
correct procedu
Dear all,
I am using an USRP2 module with a WBX daughterboard.
I am currently interested in power level measurements, and have tried
measuring band power with different decimations.
I've noticed, that if I try to measure the same exact band using different
decimation rates and their appropriate FI

Dear all,
I am trying to receive with my USRP2 + WBX daughterboard a signal band of
precisely 8 MHz in order to measure it's power.
The problem is that since USRP2 has a 100 MSample/s sampling and I can't
just devide it by 12.5 to get the desidered 8 MHz band, I need
to use an FPGA decimation of
Dear all!
Myself and my colaborators have 2 USRP2+WBX boards. We use them in the
500-700 MHz band.
The boards worked just fine until today, when we have used a stronger input
signal generated by an Agilent signal generator connected directly via
cable. The generated signal, a 2 MHz - large wideb

I also have a similar problem.
It seams there is no firmware that can support WBX,and UDP, yet.
If someone knows more about this please let us know.
Also any other solutions to our predicament would also suffice.
Thank you.
