3.7 WLAN MIMO Modulation Analysis Measurement
3.7.4 Amplitude
3.7.4.1 Y Scale
The Y Scale Tab 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 functionality depends on the
selected window. The reference line is at the top, center, or bottom of the graticule,
depending on the value of the Ref Position function.
