The analyzer has four trace buffers that are independent of the input channels: trace A,
trace B, trace C, and trace D. In addition to the individual traces, the following traces
can be active at the same time:
• A and B—trace A is the “most active” trace.
• C and D—trace C is the “most active” trace.
• ABCD—trace A is the “most active” trace.
Trace pairs AC and BD cannot be active at the same time.
The “most active” trace data is saved during a save operation and menu selections
show the “most active” trace setup.
You have many options for selecting and displaying the contents of a trace, but you
must activate the trace before you can change these options. For example, most of the
selections under the [
Marker
] and [
Display
] menus only affect the active trace.
