Explanation
• Setting the Scale
You can set the center value and the vertical zoom rate of the frame (scale/division)
used to display the computed waveform. You can select the setup mode from below.
• Auto
Enables auto scaling. The upper and lower limits on the screen display are
automatically determined from the maximum and minimum values of the computed
result.
• Manual
Enables manual scaling. You can arbitrarily set the center value and the vertical
zoom factor (scale/division).
Note
The display scale of the computed waveform may not be stable if you select auto scaling in the
cases described below. In such case, use manual scaling.
• The amplitude of the input signal used in the waveform equation is not stable.
• The amplitude of the computed waveform is near the threshold level used to switch the
scaling setting.
• Setting the Center Value and Vertical Zoom Factor (Scale/Division) for
Manual Scaling
The values can be set in the range of –9.9999E+30 to 9.9999E+30.
