Y Auto Scale (Y Scale)
Clicking Y Auto Scale rescales the y-axis of the active trace to ensure that all points within the current x-axis limits are visible.
Autoscaling the y-axis changes the values of Reference Level and Y Per Division. The new values are used until you do one of the following:
- Enter a new value for either parameter.
- Click Y Auto Scale again.
- Toggle Range Tracking from off to on.
- Change the input range while is enabled.
The last two cases do not apply when the trace format is phase or group delay.
