Numerical Calculation Procedure
7.1 Numerical Calculation Procedure
The following two methods are available:
Automatically making
calculations after
measurement
You have to congure the FFT calculation settings before starting
measurement.
(not available when the real-time save is set to on)
Making calculations using
existing data
The instrument can make calculations using waveform data that has
already been acquired or that saved on storage devices.
Performing calculation during measurement
Conguring the calculation
settings
Congure the calculation settings on the [Numerical
calculation] screen.
(p. 136)
Set evaluation criteria to evaluate calculation results.
To automatically save calculation results, congure the saving
settings before starting measurement.
• Conguring the [Calculation result] settings.
(p. 148)
(p. 86)
Starting a measurement
Acquiring data When a trigger condition is satised, the instrument
starts to acquire data.
(If no trigger is specied, clicking the start icon allows the
instrument to start acquiring data.)
Calculation The message [Calculating] appears on the screen status
bar.
The instrument calculates the data, No. 1 through No. 108 in
turn.
(To force-quit the calculation, click the stop icon.)
Displaying calculation
results
The numerical calculation result screen of the waveform
screen displays calculation results.
(p. 147)
(Evaluating calculation
results)
(Only when the evaluation setting is enabled)
(Saving results) (When the auto-save is set to [On])
The instrument automatically saves calculation results.
Finishing the measurement

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).
