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”)
The trigger functionality is related also to the Update Mode (see UPMODE Command).
When a trigger event is detected, the device action are the following:
