Click the [Area] box, and then choose an option for a calculation range.
You can specify a calculation range for each calculation.
Whole
Makes calculations using whole waveforms.
A_B Makes calculations using waveforms between trace cursors A and B.
C_D Makes calculations using waveforms between trace cursors C and D.
Choosing [A_B] or [C_D] allows you to specify the calculation range with the trace cursors on the waveform
screen. When the instrument does not acquire any waveforms, perform another measurement and specify a
range. Doing so allows you to make calculations using data acquired within the specied range from the next
measurement.
5
Click a calculation target channel.
The channel selection screen appears.
Refer to “Calculation target channels and setting contents of calculation conditions for each calculation type”
(p. 139).
6
Set calculation conditions.
Refer to “Calculation target channels and setting contents of calculation conditions for each calculation type”
(p. 139).
7
Execute calculation.
(To calculate existing data)
Click [Execute].
(To automatically make calculation after measurement)
Click the start icon.
