RIGOL Chapter 6 MATH and Measurement
6-2 DS1000Z User Guide
Math Operation
DS1000Z can realize various math operations, including:
Algebra operations: A+B, A-B, A×B and A/B
Spectrum operation: FFT
Logic operations: A&&B, A||B, A^B and !A
Function operations: Intg, Diff, Sqrt, Lg, Ln, Exp and Abs
Filter: Low Pass, High Pass, Band Pass, Band Stop
Fx operations: combination of two operations. For the details, please refer to the
introduction in "Fx Operation".
The results of math operation also allow further measurement.
Press MATH Math Operator in the vertical control area (VERTICAL) on the
front panel to select the desired operation function. Press Operation to enable the
operation. The result of math operation is displayed on the waveform marked with
"M" on the screen.
Addition
Add 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 addition 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
