T commands

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.

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
