Amplitude Markers
Amplitude markers are horizontal dotted lines that you can move to any
amplitude level on the screen. The two amplitude markers can be set
independently or used as a pair of delta markers.
Amplitude markers can be used as a visual comparison aid with the data trace.

Trace Math
Trace Math allows you to compare data traces and perform simple math. Learn
how to use Trace Math beginning on page 187. All Data and Memory features
work as documented EXCEPT for the following:
NOTE When Trace, then Data -> Mem is pressed, if a Src Power trace is active, then
RxPower is actually stored into memory.
To Compare Src Power (Input) and Rx Power (Output):
