Using Markers (IQA)
Noise Markers can be used like regular markers. A Noise Marker is
distinguished from a regular marker by (1Hz) after the marker readout value.

Band/Interval Power Marker

A Band/Interval Power marker—available in IQA and SA Modes—integrates the
power that is measured over several adjacent data points. The range of points
being measured is displayed with vertical posts around the marker. This Band
Span value is selectable.
This feature is very similar to a channel power measurement (see SA chapter,
"Channel Power (CHP)" on page
When the IQA is set to a waveform measurement, the marker is referred to as
an Interval Marker because it averages power over a specific time interval. In
this case the range is specified as the Interval Span.
