PERSIST_SAT, PESA

Command/Query

DESCRIPTION

The PERSIST_SAT command sets the level at which the color
spectrum of the persistence display is saturated. The level is

specified in terms of percentage (PCT) of the total persistence data
map population. A level of 100 PCT corresponds to the color

spectrum being spread across the entire depth of the persistence
data map. At lower values, the spectrum will saturate (brightest

value) at the specified percentage value. The unit PCT is optional.

The response to the PERSIST_SAT? query indicates the saturation
level of the persistence data maps.
