TRIGGERING

Trigger Basics

Triggering tells the ScopeMeter test tool when to begin displaying the waveform. You can select which input signal should be used as the source, on which edge this should occur, and at what waveform level it should occur. Finally, you can tell the test tool to delay the waveform to be displayed with a specified time delay, number of cycles, or number of events.

The second top row on the display identifies the trigger parameters being used. Trigger icons on the display indicate the position of the trigger delay and the trigger level. Refer to Figure 5-10.

For example,

20 ms/DIV TRIG:A

+120EVT -5DIV

means that INPUT A is used as the trigger source with a positive slope. The amount of trigger delay in time divisions is -5, and that the amount of trigger delay in events is +120.
