Operation
Quick tip
Marker controls are available directly from the front panel Marker buttons.
Markers display
You can display up to
fi
ve markers including the reference marker. Markers can all be placed on the same trace or they can
be placed on different traces. There are three types of Markers:
Reference Marker: This marker type is labeled MR in the graph. It makes absolute measurements and is also used for
calculating differences when Delta or Power readouts are enabled.
Delta Markers: This marker type is labeled M1 to M4 in the graph. It is used to measure other points on the trace or the
difference between the Marker Reference and the Delta marker.
Power Markers: This marker type is labeled M1 to M4 in the graph. It functions the same way as Delta Markers, except it
shows power density and integrated power density (dBm/Hz) instead of power level (dBm).
The following information tells you more about how markers function. For more detailed information about markers, see
the instrument Help.
When you drag markers along a trace with either the touch screen or the mouse, the marker will seek the high points.
The marker stays within 20 trace points of the mouse position. If there are no peaks within the current range of trace
points, the marker
fi
nds the highest point.
When you attach the marker to the bitmap trace in the DPX spectrum display, the marker readout indicates the hit count
for pixels (maximum 65,536) along with frequency and power (see the following
fi
gure). You can position the marker
at any point in the graph.
Markers attached to the DPX bitmap display the signal density in percent at the selected pixel, rather than the hit count.
Quick tips
If markers are turned off, click
Peak
in the Marker toolbar or on the front panel to add the marker reference (MR) and to
position it on the maximum peak level on the trace in the selected display.
Click
Table
in the Marker toolbar to open a tabular display showing the marker information.
