The FFT function can specify the calculation start position for waveforms measured by the memory
function before calculation.
Operation differs by calculation execution settings.
See: "Trigger Modes and Averaging" (p.254)
•Calculation execution: [Single]
Analysis is performed once on the specified number of analysis points beginning with the specified
starting point, and analysis results are displayed.
This is convenient for analyzing only a specific range. However, if averaging is enabled, analysis
repeats for the specified averaging count.
•Calculation execution: [Repeat]
Analysis is performed repeatedly on the specified number of analysis points beginning with the speci-
fied starting point and ending with end of waveform data, and final analysis results are displayed
(Calculation is performed for the number of specified points so a good end point becomes the final
analysis result.)

Point
Display the waveform with the Memory func-
tion.
Set the [Reference] item to [From Memory] .
Set analysis conditions such as the analysis mode and
number of analysis points (these can also be set on the
Waveform screen).
Click [DISP] in the right-click menu to display
the Waveform screen.
The one-time calculation range is displayed for the mem-
ory waveform.
