Sets (or queries) which palette to use for fast acquisition mode.

Syntax
ACQuire:FASTAcq:PALEtte
{NORMal|TEMPErature|SPECTral|INVERTed}
ACQuire:FASTAcq:PALEtte?
Arguments
NORMal – Normal displays hues and lightness levels for best overall viewing.
The color of each channel waveform matches the color of the corresponding
front-panel vertical knob.
TEMPErature - Temperature Grading displays areas of the waveform with the
highest sample density in red shades. The areas of lowest sample density appear
in blue shades.
SPECTra – Spectral Grading displays areas of the waveform with the highest
sample density in blue shades. The areas of lowest sample density appear in
red shades.
INVERTed – Inverts the normal display hues and lightness levels based on sample
intensity. The areas of lowest sample density appear the brightest, while the areas
with the highest sample density appear the darkest.
Examples
ACQ:FASTA:PALETTE SPECT sets the palette for fast acquisition mode to
Spectral.
ACQuire:FASTAcq:STATE
Turns fast acquisition mode on or off, or queries the state of the mode.
NOTE. When fast acquisition mode is on, waveforms cannot be queried, saved or
recalled, and reference waveforms cannot be turned on. Attempting any of these
results in a settings conflict error event.
