Band/Interval Power Marker - Keysight N9912A User Manual

SA (Spectrum Analyzer) Mode
SA Mode Settings
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, unique to SA Mode, 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
page
Summary:
— In Zero span, an Interval Power Marker yields the average power over the
specified time interval.
— In non-Zero span, a Band Power Marker yields the total power over the
specified frequency range.
How to measure Band/Interval Power with a marker
— Press Marker to create or select a Normal or Delta marker to use to
measure Band/Interval Power.
