The receiver noise and offset levels which are internally maintained by the RVP8
are zeroed 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 Load one pulse of data samples. Each bin within the pulse is represented by four
16-bit words which represent a single instantaneous sample. You may specify one
or more bins to be loaded; the RVP8 will replicate these data as necessary in order
to fill out the entire count of acquired bins. Thus, the total number of words
loaded is (4+4B), where B is the bin count specified in Word #1. This takes ac-
count of the four “header” words, plus four words for every bin being defined. If
B is zero, then a zero-valued sample is applied for all channels.
