Very high resolution is not very difficult to get, as long as the total bandwidth is not excessive. The maximum number of channels (spectral points) in the current design, for bandwidths below 62.5 MHz, using only one baseband, and requesting only a single polarization product (e.g., XX), is 32,768 (see §2.3, esp. example C). Thus one could achieve 1 Hz resolution over 33 kHz, so long as the appropriate low-pass filter is available at the sampler. Although the current design for the IF system has 31.25 MHz as the narrowest available bandwidth for each baseband, it would be fairly easy to modify that design to allow for narrower bandwidths for one of the baseband pairs (B. Clark 1998, priv. comm.).
