3.6 Modulation Analysis Measurement
3.6.3 Amplitude
Activates the Amplitude menu and selects Reference Level or Reference Value as
the active function, depending on the measurement.
Some features in this menu apply to multiple measurements. Some other features
apply only to specific measurements and their controls are blanked or grayed-out in
measurements that do not support the feature.
3.6.3.1 Y Scale
Contains controls that pertain to the Y axis parameters of the measurement. These
parameters control how data on the vertical (Y) axis is displayed and control
instrument settings that affect the vertical axis.
Ref Value
Sets the value for the absolute power reference.
The reference value specifies the amplitude of a signal displayed on the reference
graticule line. The reference line is at the top, center, or bottom of the graticule,
depending on the value of the Ref Position function.
The Ref Value control applies only to the selected window. The functionality
depends on the selected window.
If a Table type window is selected, the Ref Value control is unavailable.
