I think not.  It is hard to imagine any mechanical beam switching at a
rate faster than a few Hz.  None of the factors limiting the dump rate
(phase switching, hardware transfer rates, signal processing
capability) is expected to be in effect at this rate.  Besides, beam
switching like this is only for single-dish mode, where only the
autocorrelations are needed and where phase switching has no effect,
thus easing the limits considerably.
