Now select the
Markers
tab on the toolbar and click the down arrow on marker 1 to enter the setup as shown below.
There are five marker pairs (1-5) on the
Markers
toolbar. These same markers are available from the
Results
pane.
Each pair consists of a
Normal Marker
and a
Delta Marker
.
Normal Marker
is a single data point and appears above
the measurement trace.
Delta Marker
gives the differential value and appears below the trace.
Markers
are activated
by clicking on the number in the toolbar.
Set Position
You can set the marker position precisely in time by selecting
Set Position
from the marker drop down and entering a
specific value as shown below.
Only one marker can be active at a time although all five markers (or marker pairs) can be displayed simultaneously.
The active marker will have an asterisk (*) next to its number in the toolbar and the marker number will be underlined
and appear slightly larger in the display.
Once a marker is turned on (Normal or Delta) and the pointer mode is set to
Markers
, you click or click and drag on
the measurement area to position the marker. As you move the marker the notation in the upper left corner of the
measurement grid will be updated. The x value (time) is determined by the position of the cursor. The y value
(magnitude) is determined by the value of the trace closest to that point in time.
