The design, implementation and testing of the first NRAO Event Capture data acquisition system is presented. The NRAO in Green Bank is developing a set of new data acquisition systems based on the U.C. Berkeley CASPER IBOB/ADC/BEE2 hardware. We describe the hardware configuration and initial experiences with the development system. We present first astronomical tests of the Event Capture system, using the 43m telescope (140ft). These observations were carried out at 900 MHz. The observations were made on 2007 July 8 and 9 towards the Crab pulsar, the galactic center, the Moon and two test observations while the 43m was pointed at Zenith (straight up).
The Event Capture is one of several on-going FPGA based data acquisition projects being implemented for the Robert C. Byrd Green Bank Telescope (GBT) and for the 43m telescopes. The NRAO Configurable Instrument Collaboration for Agile Data Acquisition (CICADA) program is described at: http://wikio.nrao.edu/bin/view/CICADA
