The device provides 6 base triggers for you.

  • Single signal: Rising edge; Falling edge; Rising or falling edge.
  • Bus: Data, Data value delay, Data and edge

Rising edge:

Select the “Rising edge” in the tree; select the signal in the combo box. Then it will be triggered by a rising edge appeared on the selected signal.

   

Falling edge:

Trigger by a falling edge appeared on the selected signal.

Rising or falling edge:

Trigger by a rising or falling edge appeared on the selected signal.

Data:

Trigger at the appearance of a specified value on the selected bus.

Data value delay:

Trigger at x time after the appearance of a specified value

Data and edge:

Trigger at the appearance of a specified value on the selected bus and rising, falling, or rising or falling edge of the selected signal.

Advance Trigger Setup

If the base trigger can’t satisfy you, maybe you want the advance trigger. Click the “Advance” in the tree, then you can configure the advance trigger.

There are two trigger conditions: trigger A and trigger B. You can set the trigger mode by clicking the Trigger Mode group box.There are four parts in each condition, Data, Duration, Edge and the Relative trigger value.
