Acquisition System

The "Horizontal" menu allows you to configure the instrument's acquisition system.
7.1

Acquisition Mode

The acquisition mode is used to determine how the waveform points are calculated
from the sample points. In the Horizontal menu, click or tap the desired acquisition
mode for the Acquisition item. This oscilloscope provides five acquisition modes:
Normal (default), Average, Peak, High Res, and UltraAcquire. The selected acquisition
mode is indicated in the acquisition label ("A" icon) at the top of the screen.
Normal
In Normal acquisition mode, the oscilloscope samples the signal at a fixed time
interval to rebuild the waveform. This mode yields the best display for most
waveforms.
Average
In this mode, the oscilloscope averages the waveforms from multiple acquicitions to
reduce the random noise of the input signal and increase the vertical resolution. A
greater number of averages lowers the noise and increases the vertical resolution. On
the other hand, the higher the number of averages, the slower the displayed
waveform responds to waveform changes.
