The Timing Waveform Menu

The timing waveform menu differs from the other menus you have used so far in this exercise. Besides displaying the acquired data, it has menu fields that you use to change the way the acquired data is displayed and fields that give you timing answers. Before you can use this menu to find answers, you need to know some of the special symbols and their functions. The symbols are:

The green and yellow dotted lines

The red dotted line

The Green and

Yellow Dotted

Lines

The Red Dotted Line

Configuring the Display

The X and O markers are green and yellow vertical dotted lines respectively. You can use them to find your answer. You place them on the points of interest on your waveforms and the logic analyzer displays the time between the markers. The X and O markers will be in the center of the display when X to trig(ger) and O to trig(ger) are both 0.000 s (see example below).

The X marker displayed is green and the O marker displayed is yellow. The trigger marker is red.

The red vertical dotted line indicates the trigger point you specified in the Timing Trace Specification menu. The red dotted line is at center screen and is superimposed on the negative-going edge of the RAS signal.

Now that you have acquired the RAS and CAS waveforms, you need to configure the Timing Waveforms menu for best resolution and to obtain your answer.
