Alternative Triggering

The trigger signal comes from two vertical channels when you use

Alternative Triggering. Using this type of trigger, you can observe two

unrelated signals at the same time. For each signal, you can select different

trigger types, such as Edge, Pulse, Slope, or Video. Trigger information for

the two channels is displayed at the bottom right side of the display.

1. Press the Type option button and select Alternative.

2. To set up both triggers, press the Source option button and select a

Source (CH1, CH2).

3. For the selected Source, press the Mode option button and select a

Trigger Type (Edge, Pulse, Slope, or Video).

4. For the selected trigger type, set the trigger options.

5. Press the Setup option button to display the Trigger Setup menu.

You can use the Trigger Setup menu to select a coupling mode and

define a Holdoff value. Coupling modes comprise DC, AC, HF

Reject, and LF Reject. Turn the Adjust front panel knob to set the

Holdoff value.
