Horizontal & Acquisition Settings (Oscilloscope)

Last Modified: December 14, 2018

You can configure the display and the data acquisition by using the Horizontal & Acquisition settings.

You can configure some settings directly on the panel. To access additional settings, click the configuration button on the top right side of the section.

Setting Description
Time per division The horizontal scale of the display.
Repetitive sampling Specifies whether to enable repetitive sampling on the trigger signal.
  • Auto—The Oscilloscope automatically detects if all repetitive sampling conditions are met and decides whether to enable repetitive sampling on the trigger signal.
  • Off—Disables repetitive sampling on the trigger signal.
To enable repetitive sampling, you must configure the Oscilloscope as follows:
  • The trigger type must be Analog edge, and the trigger signal must be enabled.
  • The trigger mode must be Normal.
  • Sample rate must be 100 MS/s. You can increase Sample rate by reducing Time per division or the absolute value of the Position. However, that is not applicable when Acquisition delay is enabled and the value of Position is negative.

The trigger signal must be periodic and with low noise. Otherwise, the graph on the display may be distorted. You can configure Type, Mode, Acquisition delay, and Position in Trigger Settings.

Refer to Repetitive Sampling for more information.

Acquisition Filter you apply to the analog-to-digital (AD) conversion results.
  • Decimate—The Oscilloscope records only the Nth AD conversion result, where N is predefined by the Oscilloscope.
  • Average—The Oscilloscope calculates each sample as the average of the AD conversion results.
  • Min/Max—For each two samples, the Oscilloscope calculates one as the minimum value of the conversion results and the other as the maximum value of the conversion results. In other words, the maximum value and the minimum value appear by turns.
Sample rate Number of samples that the Oscilloscope acquires per second. The Oscilloscope automatically sets the value of Sample rate according to the value of Time per division and trigger settings.
Repetitive sample rate Sample rate of the trigger channel when repetitive sampling is enabled. When Repetitive sampling is Auto but not all repetitive sampling conditions are met, Repetitive sample rate returns null (- - -).

The following settings are available on the panel only:

Setting Icon Description
Expand Expands the trace by decreasing Time per division.
Shrink Contracts the trace by increasing Time per division.
