Spectrum trace handle
The spectrum trace handle provides details on the trace reference level, the source channel for the trace, and which trace types are
displayed.

1. The RF trace indicator is placed at the Reference Level. The waveform view shows the spectrum traces relative to a Reference Level
reference point. If the Reference level is above the top of the graticule, the handle is drawn at the top of the graticule and pointing up.
2. A capital M indicates that the maximum trace is enabled.
3. A capital A indicates that the average trace is enabled.
4. A capital N indicates that the normal trace is enabled.
5. The small m indicates that the minimum trace is enabled.
Highlighting around a letter indicates that trace type is selected. In the figure, the small m is highlighted, indicating that the minimum trace
is currently selected.
There is an important distinction between enabled and selected traces:
• An enabled trace letter (displayed in the trace handle) means that trace type is being displayed.
• A selected trace (highlighted around the letter) is the trace that is used for measurements, marker readouts, and cursor readouts.
