     3=== Description ===
    44In this tutorial we'll use the 2 USRPs on Sandbox 3 to transmit and receive a single frequency over the air to demonstrate the use of ''Universal software Radio peripheral'' Hardware Drivers (UHD) which  is used standalone to configure and enable the USRPs. This tutorial can be run on other USRP2s available of the grid as well. For details on available USRP2s on the grid, please see [http://www.orbit-lab.org/wiki/Hardware/fDevices/gUSRP#GRID available USRP2 HW].

    77 1. Sandbox 3 - consists of two nodes (node1-1 & node1-2). Each node has a USRP2 connect via Ethernet.
    88 2. ''ubuntu-12-04-uhd.ndz'': disk image loaded onto nodes. This image has all the precompiled - software required to configure the USRPs and analyze recorded data. The USRP2's interface with the node is already configured.
