Overview of Softkey Menus
This sections describes the Noise Figure's Measure, Measure Setup softkeys,
and related sub-menu softkeys.
1. Define a measurement type.
Noise Figure has asymmetrical uncertainty (i.e., log measurement). Noise
Factor and Noise Temperature have symmetrical uncertainty (i.e., linear
measurement). Uncertainty is not displayed for Gain and Y-Factor.
