The New ARO 2 GHz Filter Bank
Abstract
A new 1 MHz resolution, 2048 channel filter bank has been installed at the Arizona Radio Observatory Sub-millimeter Telescope on Mt. Graham. This instrument has been built using modern surface mount technology, which results in an extremely compact and reliable design. Each channel has an automated gain and offset control, maximizing the dynamic range. The filter bank can be configured into 1 x 2048, 2 x 1024, 4 x 512 or 8 x 256 channel operating modes, and can accept up to eight I.F. inputs for use with multi-beam receivers such as the DesertStar array. Preliminary results of initial testing and observing will be presented and technical performance will be discussed. The design is currently being extended to include a 512 channel, 250 kHz filter bank.
