| 2008-09-26 | Posted By: Norton Allen Scalable Signal Processor Takes to the Air The Anderson Group's Scalable Signal Processor board (SSP) completed it's maiden voyage aboard NASA's WB-57 research aircraft during the recent NOVICE mission. The SSP is a high-speed analog to digital converter with onboard signal processing based on the Xilinx Virtex-4 FPGA. It records up to three channels at raw sample rates up to 100 MHz, then performs onboard averaging and coadding to reduce the overall data rate. Communication and data retrieval is performed via TCP/IP over ethernet. A Matlab GUI is available for testing and lab use, and a full-featured driver integrates the board into the Anderson Group data acquisition architecture. Funding for the development of the SSP came from NASA's Instrument Incubator Program.  Discussions |
