7.3 Setup Operating Parameters (SOPRM)
This command is used to configure the Signal Processor. The command
should be issued whenever any of the parameters in the list change. The
default parameter list consists of twenty 16-bit input words. These can be
followed by optional XARG parameters as needed.

NTh If 1, then no threshold values are set. This means ignore input words
4, 5, 6, 7, 11, 12, 13, 14, and 18. This is usually used in conjunction with
the THRESH command (see Section 7.29 Set Individual Thresholds
(THRESH) on page 329), when setting individual thresholds.
0916-069
The sample size is continually adjustable from 1 to 256 pulses. However,
during the alternating polarization mode, the sample size must be even. If
an odd value is entered it is rounded up by one in that case.
