Single
Press this soft key to display the active trace (or traces) at full size in the sweep window. If more than one trace is selected by the Number of Traces soft key, then the traces are displayed overlapping in the sweep window.
Dual
Press this soft key to display 2 traces in the sweep window, with the sweep window divided horizontally into 2 equal rectangles.
Tri
Press this soft key 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.
Quad
Press this soft key to display 4 traces in the sweep window, with the sweep window divided horizontally and vertically into 4 equal rectangles.
Back
Press this soft key to return to the Measure Menu without changing the Trace Format setting.
Regardless of the Trace Format that is selected, the number of traces that are displayed is controlled by the Number of Traces soft 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 traces 1 and 3 are displayed overlapping in the upper sweep window, and traces 2 and 4 are displayed overlapping in the lower sweep window.
If 4 traces are displayed in Tri Trace Format mode, then traces 1 and 2 are displayed individually in the upper half of the sweep window, and traces 3 and 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 section of the sweep window, and any other sections are blank.
