Preset 1
Time Line
Activates an adjustable vertical line that is used as a visual reference line. The line’s
horizontal position corresponds to its time value. The value of the Time Line (for
example, 1ms) appears at the top of the display, to the right or left of the line
justified as required for it to be on-screen, marked TL1 for Time Line 1, TL2 for Time
Line 2, etc.
This key controls whichever Time Line has been selected by "Select Time Line" on
page 272.
The Time Line can be adjusted using the step keys, knob, or numeric keypad. It can
also be dragged on the display with your finger or a mouse. If more than one window
has a Time Line, the Time Line of the selected window is controlled.
If the Time Line is off-screen, it shows as a line at the left or right of the screen. As
with all such lines (Pk Thresh, Trigger Level, etc.) it is drawn on top of all traces.
