A fairly detailed design for the Millimeter Array (MMA) correlator was proposed by Escoffier (1997), in MMA Memorandum 166. In this memorandum we set forth more explicitly the astronomical capabilities of that correlator, concentrating on the number of channels (spectral points) produced. We also comment on the extent to which that design might be expanded if necessary (e.g., to accommodate more antennas).
For concreteness we assume throughout that linear polarizations (X and Y) are recorded.
