Acquisition System
The "Horizontal" menu allows you to configure the instrument's acquisition system.
Figure 7.1 Horizontal Menu
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 four acquisition modes:
Normal (default), Average, Peak, and UltraAcquire. The selected acquisition mode is
indicated in the acquisition label ("A" icon) at the top of the screen
Acquisition
Mode
Normal
In Normal acquisition mode, the oscilloscope samples the signal at a fixed time
interval to rebuild the waveform. This mode produces the best display for most
waveforms.
Average
In this mode, the oscilloscope averages the waveforms from multiple acquisitions 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 response of the
displayed waveform to waveform changes.
