Hi all,
I got the USRP and would like to use it to run some examples. Does any one have
the instruction files for new users? I read
http://www.nd.edu/~jnl/sdr/docs/tutorials/4.pdf . I feel a kind of embarrassed
to ask this kind of stupid questions. How can I remove the USRP from my laptop

However, I have no idea where the destination is. I thought I can get
the data through GNU Radio and then use Matlab to draw the spectrogram
to show the spectrum holes. In line 193, the connection seems without
the destination.

Hi there!
I'd like to know if there is in development or already available a
daughterboard for the USRP that could transmit in the UHF band of 470Mhz ~
700Mhz.
I'd like something like a TVTX :)
Thanks,

Yes, I think I only need to know the power strength and don't need to decode
the signals for searching the spectrum holes. I read the
usrp_spectrum_sense.py. I wonder how I can draw a spectrogram through this
program. I think the line 145 shows the source is the USRP. However, I have no
idea w

*If* you are going to make a custom FPGA build, one could do as follows:
Since there are two ADCs operating on quadrature downconverted samples
at 64 Msps, the spectral width is actually 64 MH

It needn't be so difficult. There's a lot of jargon and domain-specific
material in [1] and [2], but the principle is pretty straightforward.
There are two

Hi
I was wondering if anyone could please help me? I'm doing some
measurements on the Microtune Cable modem module. I already modified
the .py file to be able to set the 3 gain stages independently. I am
trying to see how the gains should be set to get an input signal of
2Vp-p to the ADC to be

Hi all,
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 can I scan the whole ISM band and draw the
spectrogram of the ISM band,2.4-2.4835GHz, through
12 matches
