ACQuire:FASTAcq
Sets or queries the FastAcq feature. This feature provides a high-speed waveform
capture rate to help capture signal anomalies.

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.

Arguments
1 or ON turns on f
ast acquisition mode.
0 or OFF turns it off.
Examples
ACQ:FASTA:STATE ON turns on fast acquisition mode.
ACQuire:MAGnivu
Turns on the MagniVu feature, which provides up to 32 times signal detail forfast
viewing of short events. This feature is not recommended for slow data formats
such as RS-232.
NOTE. MagniVu channel sampling is available on MSO/MDO4000/B
oscilloscopes only as well as MDO3000 and MDO4000C models with option
MDO3MSO or MDO4MSO installed.

Arguments
<NR1> = 0 disables the MagniVu feature; any other value turns this feature on.
ON enables the MagniVu feature.
OFF disables the MagniVu feature.
ACQuire:MAXSamplerate? (Query Only)
Returns the maximum real-time sample rate, which varies from model to model.
