Autotrigger
:INPut:AUTO?
If auto is on, the counter automatically controls the trigger level
1
and the hyster

esis. If you have a stable amplitude, use the :AUTO ONCE, and auto will determine
the trigger level once, and then set fixed levels.
Parameters
<Boolean> = ( 1/ON | 0/OFF )
ONCE means that AUTO first switches ON to check the signal. After determining suitable sen

sitivity and trigger level setting, it programs these values as if they where manually set.
It ends by switching off AUTO.
Using ONCE instead of AUTO ON improves measuring speed.
