In Format #3 (new in the RVP900) each bin within the pulse is represented
by two 16-bit floating point words having the exact same format as the
packed (I,Q) time-series data that are output by the PROC command (See
Section 7.7 Initiate Processing (PROC) on page 275). Compared to the
legacy 4-word format, this 2-word format uses half the I/O bandwidth, has
superior dynamic range, and allows data to be fed back into the signal
processor in their native packed format. The total number of words loaded
(including the initial header section) is (4+2B), where B is the bin count
specified in Word #1.
