Using the Navigator Teledyne LeCroy Corporation
corresponds to the last packet. The Navigator bar is made up of three parts: Pre and Post‐
Trigger traffic, Errors, and Types of Traffic.
At any time, a line in the navigator bar of one pixel in height represents a fraction of the
trace data. If the Navigation bar is 400 pixels high, then each bar in this example would
represent 1/400 of the trace. If the trace had 4000 packets total, each bar would
represent ten packets. In the Types of Traffic portion of the navigation bar, the color of the
bar would be that of the most important item in those ten packets.
Drag the yellow caret, at the top or bottom, to set the packet range. When you move the
caret, a message shows the packet range.
The blue caret indicates the current packet position in the trace view.
9.9.2 Navigator Toolbar
The Navigator toolbar lets you quickly set Navigator features. The toolbar has two
buttons.
Navigator Ranges: This button brings up a pop‐up menu that lets you reset the Navigator
range. The range determines what packets are viewable in the trace display.
Navigator Panes: This button has two purposes: To select which Navigator panes appear
and to bring up the Navigator legend. The legend determines how information is shown in
the panes.
9.9.3 Navigator Ranges
You set the viewing range by dragging the yellow range delimiters along the slider.
To set the lowest packet viewable, drag the top delimiter up. As you do so, a tool tip
appears to indicate the current range. Stop dragging when you reach the desired lowest
packet.
