PNSM
Pseudo Noise Signal Mode
Class
Signal Analyzer - Pseudo-random noise
Description
Determines how the pseudo-random noise sequence seed and run-length are determined.
Command syntax
PNSM mode
mode
0 = Auto mode. The sequence seed and run-length parameters are set automatically.
The seed is automatically set to 0x08000001. Noise values are advanced according to
the current setting of the
parameter. If PNSA is set to 0 (every pixel), the
sequence length is automatically set to the total number of pixels (per frame) minus
one. Alternately, if PNSA is set to 1, noise is advanced every active pixel, and the
length is set to the size of the HRES*VRES active area (per frame) minus one.
1 = Manual mode. The sequence seed and run-length must be manually set using the
and the
commands.
