USRP

The USRP is an Software Defined Radio created by Ettus Research. I have one with a WBX daughterboard.

For various notes and experimental results concerning the USRP, please have a look at the dedicated page on my wiki.

The WBX is connected to an HP 8640B signal generator (on the left under the CRO).

The WBX can receive signals from a broad frequency range, for example 2G and 3G mobile networks:
