Numerical Calculation Procedure
Making calculations using existing data
(Loading data) (To load measured data from a storage device to use for
calculation)
(p. 94)
Conguring the calculation
settings
Congure the calculation settings on the [Numerical
calculation] screen.
Set evaluation criteria to evaluate calculation results.
(p. 136)
(p. 148)
Performing calculation Choose [Execute] to execute calculations.
(To force-quit the calculation, click the stop icon.)
Displaying calculation
results
The waveform screen displays numerical calculation
results.
(p. 147)
(Evaluating calculation
results)
(Only when the evaluation setting is enabled)
(Saving results) Save calculation results as needed.
• To save the calculation results, click the save icon.
To specify a range for calculation
Before executing the calculation, specify a calculation range with the trace cursors on the waveform
screen. Set [Area] to [A_B] or [C_D] on the [Numeric calculation] screen.
Refer to “7.2 Conguring the Numerical Calculation Settings” (p. 136).
