The ``galspect'' Spectrometer

The ``GALFA'' spectrometer (galspect) is an FPGA-based back-end, custom-built by Jeff Mock for Galactic HI spectral-line data acquisition with the ALFA 7-beam receiver. The ``galspect'' spectrometer acquires both a 512-point spectrum over 100 MHz, and a parallel 8192-point spectrum over 7.14 MHz, usually centered near 1420 MHz.
