Set frequency and bandwidh

GNU Radio
1

hi,

I have written a signal processing module.
This module need the baseband samples of a signal at frequency=f0 and
bandwidth=B.
I am thinkin to use the usrp according to this scheme:

| antenna |
| |
| | |
| | RF front end
| | USRP
| |Computer |
|-------------------------|
|-------RF_frontend_IF_FREQUENCY------| |-----baseband------|
|

it is possible to use GNU radio to do this ???

what i need is to have control on wich part of the spectrum the usrp
traslate in baseband and the bandwidth.

My processing module is a C/C++ class.

Thank you all

Yes.

You will either need to a) use the low-level C++ interface to the USRP,
bypassing the GNU Radio framework, b) wrap your existing C++ module with
a custom GNU Radio signal processing block.
