Trace Format and Number of Traces
Use Single trace format to display the active trace (or traces) at full size in the sweep window. If more than one trace is selected by the # of Traces submenu key, then the traces are displayed overlapping in the sweep window.
Use Dual trace format to display 2 traces in the sweep window, with the sweep window divided horizontally into 2 equal rectangles.
Use Tri trace format to display 3 traces in the sweep window, with the sweep window divided horizontally and vertically so that 2 equal rectangles share the upper half of the window, and one wide rectangle occupies the lower half of the window.
Use Quad trace format to display 4 traces in the sweep window, with the sweep window divided horizontally and vertically into 4 equal rectangles.
Regardless of the Trace Format that is selected, the number of traces that are displayed is controlled by the # of Traces submenu key.
Examples:
If 4 traces are displayed in Single Trace Format mode, then all 4 traces are displayed overlapping in the sweep window.
If 4 traces are displayed in Dual Trace Format mode, then Trace 1 and Trace 3 are displayed overlapping in the upper sweep window, and Trace 2 and Trace 4 are displayed overlapping in the lower sweep window.
If 4 traces are displayed in Tri Trace Format mode, then Trace 1 and Trace 2 are displayed individually in the upper half of the sweep window, and Trace 3 and Trace 4 are displayed overlapping in the lower sweep window.
If 4 traces are displayed in Quad Trace Format mode, then all 4 traces are displayed individually in the sweep window, each trace occupying one quarter of the sweep window.
If 1 trace is displayed in Dual, Tri, or Quad format, then that trace is displayed in the first quarter section of the sweep window, and any other sections are blank.
