Perform calculation automatically after measurement starts. The operation differs
depending on the function.
• Highspeed: Calculates automatically after reading for specified recording length.
• Realtime: Calculates in real time during measurement.
In the case of the Real-time Function, the calculation value can also be saved in text
(CSV) format at a specified interval (p. 102).
Numerical calculations can also be saved automatically (p. 102).

(Open/confirm the setting information.)
Select the [Setting] screen.
A-B: Calculates between A and B.
Specify the range to calculate in the waveform
screen with cursors A and B.
When a waveform has not been read by the in-
strument, perform measurement once and then
specify the range so that calculation will be per-
formed within that range from the next measure-
ment.
(*) In the case of automatic calculation, calculating between A and B is not possible
when using the Real-time Function. To calculate between A and B when using the
Real-time Function, perform the calculation again after measurement ends. (p. 183)
