Procedure
To open the screen: Right-click and select [DISP] Waveform screen
Reading measurement values of past waveforms by cursor
After measurement is finished, read the values of each waveform by cursor.
The older the waveform,
the larger the number.
1 Click [WAVE] in the right-click menu.
2 Select a waveform.
Rotate the mouse wheel to select the
waveform.
(The waveform number is displayed in the
lower right of the screen.)
3 Move the cursor.
Click [AB CSR] in the right-click menu, and
rotate the mouse wheel to read the cursor

12.6 Saving Analysis Results
272
The saving procedure is the same as for the Memory function.
See: "Chapter 4 Saving/Loading Data & Managing Files" (p.83)
The size of saved files depends on the save format and analysis method.
See: "Appendix 2.1 Waveform File Sizes" (p.A2)
When FFT Analysis Results are Saved as Text
Divide files by calculation item and then save.
