In the legacy format #2 (RVP5-RVP900) each bin within the pulse is represented by four 16-
bit fixed point words. The total number of words loaded is (4+4B), where B is the bin count
specified in Word #1. This takes account the 4 header words, plus 4 words for every bin
being defined.

In format #3 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 8.8 Initiate Processing (PROC) (page 255).
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.
