With a Noise Marker present, the Res BW can be changed and the displayed
noise floor will also change, but the Noise Marker readout will remain about
the same.
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—accumulates
the power that is measured over several adjacent data points (or 'buckets').
The range of buckets 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
(CHP)" on page
When the frequency span is set to Zero span, the marker is referred to as an
Interval Band Marker because it averages power over a specific time interval.
In this case the range is specified as the Interval Span. Learn more about Zero
span measurements in
If the Detection method and Averaging type are set to Auto when you enable a
Band/Interval Power marker, the Detection method will change to Average
(RMS) and Averaging type will change to Power average. Other Detection
methods or Averaging type settings will usually cause measurement
inaccuracy. Learn more about Detection method in

Summary:
— In Zero span, an Interval Power Marker yields the average power over the
— In non-Zero span, a Band Power Marker yields the total power over the
