Automatically Specifying the Trigger Level (Auto-
trigger Level)
When you enable this setting, the instrument performs a preliminary measurement before an actual
measurement.
In the preliminary measurement, the instrument acquires the specied number of data points and
calculates the average value of them. Then, the instrument species the average value as the
reference of the out trigger and performs the actual measurement using this trigger.
This function is useful when you use the out trigger setting with the trigger and alert functions.
