Analysis With the Waveform Screen
13.8 Analysis With the Waveform Screen
13.8.1 Analyze After Specifying an Analysis Starting Point
The FFT function can specify the calculation start position for waveforms previously measured using the
memory function.
Operation differs depending on the calculation execution settings.
Refer to “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 specified 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).
To Verify the Analysis Starting Point While Viewing Analysis Data
3
Press the STATUS key to display the [Status]
sheet of the Status screen.
2
Switch to FFT function.
1
Display the waveform with the Memory
function.
4
Set [Reference] 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).
