Auto Scaling
Toggles the Auto Scaling function between On and Off. When Auto Scaling is On, and the Restart front-
panel key is pressed, this function automatically determines the scale per division and reference values
based on the measurement results.
When you set the value of either Scale/Div or Ref Value manually, Auto Scaling automatically changes to
Off.
Details of the Auto Scaling functionality depend on the selected view and window, as described in the
following sections:
•
"Auto Scaling: I/Q Error View - EVM Window" on page 2298
•
"Auto Scaling: I/Q Error View – Mag Error Window" on page 2298
•
