2.3.1. TRIGGER Command

The TRIGGER command allows to set and read the trigger configuration.

Warning

  • The trigger option can be used only when the Optional Board with Trigger input is installed on the device - see Optional Boards.

  • The information regarding the Trigger level and relative logic thresholds are present in the User’s Manual

The trigger events can be configured in the following ways:

  • OFF: Trigger input is ignored, the trigger event is not detected

  • POS: The trigger event is detected at positive edge of the trigger input signal

  • NEG: The trigger event is detected at negative edge of the trigger input signal

  • BOTH: The trigger event is detected at both edges (positive + negative) of the trigger input signal

  • LOW: The trigger event is detected when the trigger input signal is low (acts as a “gate signal”)

  • HIGH: The trigger event is detected when the trigger input signal is high (acts as a “gate signal”)
