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.

Memory features work as documented EXCEPT for the following:
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):
1. Meas Rx Power
2. Store to memory
3. View Data & Memory
4. Meas Src Power.
