Graph Functions
This section describes the commonly used graph functions which allow you to
perform peak searching, configure the markers, select the marker position on the
graph, or maximize the graph view to the full display size by pressing the
corresponding key on the Graph panel.
Peak search
This function enables you to place a marker on the peak or minimum of the graph.
You can set the threshold level that the marker can identify as a peak or minimum
on the graph. If the trace is above the threshold level, it will be identified as a
peak, whereas the trace below the threshold level will be identified as a minimum.
Use the knob on the U8903A front panel to move the threshold level along the
plot. The X-axis and Y-axis values of the marker will be displayed at the top right
of the graph when you place a marker at either the right or left peak, or right or
left minimum of the graph.
To access the peak search function, press
on the Graph panel. The Peak
Search menu is shown as follows.
