Hy Marcus, are you sure? I think the problem is related to the setting of
parameters of the USRP2 like decimation, interpolation, sample time, etc. ..
However I try to follow your advice and post in a public maining list you
suggested. Thank you very much.

Then, I use Windows Storage Server 2003, an Agilent N9010A spectrum analyzer
that uses the 89601 VSA software. Attached to the message two Simulink
models. The first run the signal receiving and recording in a file, the
second forward to the analyzer through USRP2.
How should I set the parameter
Hy Matt, I know the Nyquist theorem :-D , but here the problem is not as
simple as that. The problem is that changing the interpolation, the
bandwidth of the signal sent by USRP2 and displayed on spectrum analyzer
does not change. Not only that, the displayed signal is not stable at all.
I tried

The allowable bandwidths for the USRP2 are in the range 100Msps /
([4...512]). The

The USRP2 runs at 100 Msamples/sec. There is no integer decimation
factor that will yield exactly 8 Msamples/sec for an
I do not understand what you mean by "proper" bandwidth. And what are these

Hi!! 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
