Function Operation - Rigol DHO900 Series User Manual

Math Operation
• Main indicates that the measurement range is within the main time base region.
• Zoom indicates that the measurement range is within the zoomed time base
region.
To use "Zoom", first enable the
System
menu.
Expand
The oscilloscope supports two vertical expansion modes: GND (default) and Center.
• GND: When the vertical scale is changed, the math operation waveform will
expand or compress about the ground level of the signal.
• Center: When the vertical scale is changed, the math operation waveform will
expand or compress about the center of the display.
Auto Set
Click or tap AutoSetting to adjust the vertical scale and the offset of the operation
results to the optimal value according to the current configuration for you to better
observe.
Label
It is used to set the label for the math operation results. For setting methods, refer to

Function Operation

In the Math menu, click or tap the Operator drop-down button to select the desired
function operation. The available function operation types of this oscilloscope include
Intg, Diff, Sqrt, Lg (Base 10 Exponential), Ln, Exp, Abs, and AX+B.
• Intg: calculates the integral of the selected source. For example, you can use
integral to measure the area under a waveform or the pulse energy.
• Diff: calculates the discrete time derivative of the selected source. For example,
you can use differentiate to measure the instantaneous slope of a waveform.
• Sqrt: calculates the square roots of the selected source point by point and
displays the results.
• Lg (Base 10 Exponential): calculates the base 10 exponential of the selected
source point by point and displays the results.
