A modular front-end, called a daughterboard, is used for analog operations such as up/down-conversion, filtering, and other signal conditioning. This modularity permits the USRP to serve applications that operate between DC and 6 GHz.

In most use-cases, these complex samples are transferred to/from applications running on a host processor, which perform DSP operations. The code for

The USRP2 was developed after the USRP and was first made available in
September 2008. It has reached end of life and has been replaced by the USRP N200 and USRP N210. The USRP2 was not intended to replace the original USRP, which continued to be sold in parallel to the USRP2. This first generation

The original USRP, USRP2, USRP E1xx, USRP N2xx and X3xx families feature a modular architecture with interchangeable daughterboard modules that serve as the RF front end. Several classes of daughterboard modules exist: Receivers, Transmitters and
