Delta Markers

To use the delta function you position the Normal Marker at the desired point then select Delta Marker. You set the
Delta Marker (using the mouse pointer) in a manner similar to positioning the Normal Marker. Zoom and Scroll can
be used to more precisely locate the markers. The following two screen shots demonstrate first the Normal Marker
and then the Delta Marker functions.
First, Highlight a single pulse in the panorama as previously described. Next, select the Markers tab on the toolbar
and select Normal Marker from the Markers 1 drop down as shown. You can also right click on the marker tree in the
Results pane to access this drop down for each individual marker. Marker 1 will appear at center graticule in the
Measurement view. Expand the markers tree if it is not visible. Now click anywhere on the trace (the rising edge in this
example) to set the marker position. Notice that the marker value (power and time) is visible in the Results pane and
above the grid in the Measurement view (Mkr1).
NOTE: Only one marker can be active at a time. The active marker will have an asterisk (*) before its number in the
Markers toolbar. The marker tree in the Results pane will not show the active marker.
The Delta Marker function is demonstrated next from this same screen shot.
