3.7 WLAN MIMO Modulation Analysis Measurement
Scale/Div
For measurements that support a logarithmic Y-Axis, Scale/Div sets the height of
one division of the graticule in the current Y-Axis unit.
Scale/Div also determines the displayed amplitude range in the log plot graph.
Since there are usually 10 vertical graticule division on the display, the total
amplitude range of the graph is typically 10x this amount. For example, if Scale/Div
is 10 dB, then the total range of the graph is 100 dB.

Ref Position
Positions the reference level at the top, center or bottom of the Y Scale display.
Changing the reference position does not change the reference level value.
