Abstract (from CDS):

The core architecture, tests in the lab and first results of a Fast Fourier Transform (FFT) spectrometer are described. It is based on a commercially available fast digital sampler (AC240) with an on-board Field Programmable Gate Array (FPGA). The spectrometer works continuously and has a remarkable total bandwidth of 1GHz, resolved into 16384 channels. The data is sampled with 8 bits, yielding a dynamic range of 48dB. An Allan time of more than 2000s and an SFDR of 37dB were measured. First light observations with the KOSMA telescope show a perfect spectrum without internal or external spurious signals.
