Defining Simple Trigger Events

  1. In the Edit menu, select Define trigger.

    The Define display trigger condition window opens.

  2. Select a trigger mode by clicking the Analogue channels or the Bit channel option.

    Trigger conditions can only be defined for either analog or bit channels.

  3. In the Channel combo box, select a channel.
  4. In the Compar. operator combo box, select a comparison operator.

    The following operators are available: == (equal), > (greater than), < (less than), exceeds and falls short.

  5. Do one of the following:

    • In the Compare with combo box, select the channel you want to compare with the first.
    • Enter a number, true or false.

    You must use a point as decimal point. Using a comma will produce an error message.

  6. Click Accept.

    The condition you defined in the previous steps is written to the text field.

  7. As an alternative to the preceding three steps, you can enter the condition directly in the text field.
  8. Click OK to close the window.

    The trigger condition is now defined. It is automatically, and will be used when you start the experiment.
