TRIGger:A
Sets the instrument trigger level to 50% of the minimum and maximum values of
the signal. Returns the current A trigger settings when used as a query.
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.

Arguments
SETLevel sets the A trigger level to 50% of the minimum and maximum values
of the trigger source input signal. This is equivalent to pressing the front-panel
PUSH to SET to 50% button.
Examples
TRIGger:ASETLEVEL sets the A trigger level to 50% of the range of the
minimum and maximum values of the trigger input signal.
TRIGGER:A? might return a long response with A trigger parameters, some of
