13.8 Analysis with the Waveform Screen
234
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.218)
•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.)
