Multiplication
Multiply the waveform voltage values of signal source A and B point by point and
display the results.
Press MATH Math Operator to select "A×B":
Press Operation to enable or disable the multiplication operation function.
Press SourceA and SourceB to select the desired channels (CH1, CH2, CH3,
CH4 or fx (please refer to the introduction in "
Fx Operation")).
Press Offset and use to adjust the vertical position of the operation results.
Press Scale and use to adjust the vertical scale of the operation results.
Press Scale Reset to adjust the vertical scale of the operation results to the
optimal value according to the current configuration.
Press Options to set the start and end points of the operation results, enable or
disable waveform invert, etc.
― Press Start and use to set the start point of the operation results.
― Press End and use to set the end point of the operation results.
― Press Invert to enable or disable the inverted display function of the
waveform.
― Press Auto Scale to enable or disable the auto scale function. When auto
scale is enabled, the instrument will adjust the vertical scale of the
operation results to the optimal value according to the current
configuration.
― Press fx Operator, fx A and fx B to set the operator and signal sources of
the inner layer operation of Fx operation (please refer to the introduction in
"
Fx Operation").
Note: Sens. and Smooth are grayed out and disabled. Sens. is only available
when a digital channel is selected as the source. Smooth is only available for
differential operation.
You can also use HORIZONTAL POSITION and HORIZONTAL
SCALE to adjust the horizontal position and scale of the operation results.
Division
Divide the waveform voltage values of signal source A by that of source B point by
point and display the results. It can be used to analyze the multiple relationships of
waveforms of two channels.
Note: When the voltage of signal source B is 0V, the division result is invalid and
"NAN" is displayed at the bottom of the screen.
Press MATH Math Operator to select "A/B":
Press Operation to enable or disable the division operation function.
