GNU Radio

​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

• Basic RX (and Basic TX) - 2 - 200 MHz
• RFX2400 2.3-2.9 GHz Transceiver, 50+mW output
• RFX900 800-1000MHz Transceiver, 200+mW output
• RFX400 400 MHz - 500 MHz Transceiver, 100+mW output
• XCVR2450 2.4-2.5 GHz and 4.9 to 5.85 GHz Dual-band Transceiver, 100+mW output on 2.4 GHz, 50+mW output on 5GHz

USRP (1)

Uses USB and has 2 RX/TX chains and thus supports up to 2 transciever boards. There are 9 USRPs in the main grid and 2 USRPs in sandbox5 that are attached to the Orbit node.

USPR2

USRP2 is a successor of USRP. It has a single RX/TX interface, faster A/D and D/A, larger/faster FPGA and uses GigE for connection to GNU Radio host. Because of these higher bandwith capabilities, the USRP2 boards are connected to third generation Orbit nodes that are currently off the grid (listed location is just for peripheral itself); USRP2 is in its beta release currently and is supported only on Linux.
