Specify the location of the analysis input data using
the jog and shuttle controls.
Jog
Moves the analysis starting point.
Shuttle
Scrolls the Memory waveform.
To change the number of
analysis points The setting can be changed at the top of the Waveform screen.
The range is determined by the number of analysis points.
If the analysis range (number of points) is larger than the memory waveform as
shown below, analysis is not performed.
To analyze only a certain
portion If [Exec] is [Single] in the setting items at the right side of the screen, only the cal-
culation range currently displayed can be calculated.
For settings other
[Single] , calculation points are calculated until the final data.
To stop mid-way, press the STOP key.

waveform for one pass is displayed.
Memory Waveform
