Spectrum Emission Mask Measurement
AMPTD Y Scale
Ref Position
Positions the reference level at the top, center or bottom of the Y scale display. Changing the reference position does not affect the reference level value.
Auto Scaling
Toggles the Auto Scaling function between On and Off.
When Auto Scaling is On and the Restart front-panel key is pressed, the analyzer automatically determines the scale per division and reference values based on the measurement results. When you set a value to either Scale/Div or Ref Value manually, Auto Scaling automatically changes to Off.
