In the legacy Format #2 (RVP5-RVP900) each bin within the pulse is
represented by four 16-bit fixed point words. Thus, the total number of
words loaded is (4+4B), where B is the bin count specified in Word #1.
This takes account of the four "header" words, plus four words for every
bin being defined.
1 Enable processing of simulated data. Subsequent PROC
commands will use the data supplied in the next N (N =
sample size) LSIMUL commands with Operation= 2.
The receiver noise and offset levels which are internally
maintained by the RVP900 are set to their special
simulated values (from the M+ setup menu) by this
command. This is because the measured offsets are not
relevant to the simulated data, and must not be used in the
subsequent computations. Thus, it is important to issue the
SNOISE command before resuming the acquisition and
processing of live radar data.
2 or 3 Load one pulse of data samples beginning with the
following 4-word header, and continuing with an array of
items each representing a single instantaneous sample of
(I,Q) data. You may specify one or more bins to be loaded,
and the RVP900 will replicate these data as necessary in
order to fill out the entire count of acquired bins. If the
number of bins is zero, then a zero-valued sample is
applied for all channels.
