= GNU Radio = [http://www.gnuradio.org GNU Radio] is a free software development toolkit that provides runtime signal processing blocks to implement software radios using commodity PC platform. GNU Radio applications are primarily written using the Python programming language, while the supplied, performance-critical signal processing blocks are implemented in C++. == USRP == There are 9 USRPs in the main grid and 2 USRPs in sandbox5 that are attached to the Orbit node. {{{ #!rst +-----------------+-------------+-----------+ | Node Coordinate | Side A | Side B | +=================+=============+===========+ | GRID | +-----------------+-------------+-----------+ | [1,2] | FLEX-400 | FLEX-2400 | +-----------------+-------------+-----------+ | [1,19] | FLEX-400 | FLEX-2400 | +-----------------+-------------+-----------+ | [20,19] | FLEX-400 | FLEX-2400 | +-----------------+-------------+-----------+ | [10,11] | FLEX-400 | FLEX-2400 | +-----------------+-------------+-----------+ | [20,2] | FLEX-400 | RFX-2400 | +-----------------+-------------+-----------+ | [15,5] | FLEX-900 | RFX-2400 | +-----------------+-------------+-----------+ | [15,15] | XCVR-2450 | RFX-2400 | +-----------------+-------------+-----------+ | [5,15] | FLEX-900 | FLEX-2400 | +-----------------+-------------+-----------+ | [5,5] | XCVR-2450 | RFX-2400 | +-----------------+-------------+-----------+ | Sandbox 5 | +-----------------+-------------+-----------+ | [1,1] | Basic TX/RX | . | +-----------------+-------------+-----------+ | [1,2] | Basic TX/RX | . | +-----------------+-------------+-----------+ }}} == USPR2 == USRP2 is a successor of USRP developed by Ettus Research.
