| | 5 | The USB Noise Generator shown in figure 1 is primarily used as a controllable noise source, an important parameter in defining signal-to-noise ratios used for creation of different RF topologies in the ORBIT grid. Upwards of 100 of these generators will be deployed among ORBIT’s 400 nodes supplementing primary [wiki:Internal/InterferenceInjection/Overview interference injection grid]. |

| | 7 | The generator consists of two PCBs: [wiki:Internal/USBNoise/BaBo BaBo] (Baseband Board) and [wiki:Internal/USBNoise/WiBo WiBo] (Wireless Board). !BaBo performs overall control functions, baseband I/Q data generation and acquistion, data processing and transmission to upstream data servers through a USB interface. !WiBo is a radio transceiver board providing half duplex (one-at-a-time receive-only or transmit-only) upconversion/downconversion in one of three frequency bands, namely 4900-5300 MHz, 5400-5875 MHz or 2400-2500 MHz corresponding to the IEEE 802.11 a/b/g world-wide standards, respectively. |
