TRIGger:A
Sets the A trigger level automatically to 50% of the range of the minimum and
maximum values of the trigger input signal. The query returns current A trigger
parameters. The trigger level is the voltage threshold through which the trigger
source signal must pass to generate a trigger event. This command works for the
following cases: Edge Trigger (when source is Not Line), Logic Trigger (when
Clock Source is not Off or Logic Pattern is Don’t Care), and Pulse Width Trigger.
