Operation & Calibration
trigger occurs when the analog trigger signal crosses above
(above high) or below (below low) the pre-defined voltage level.
The range of trigger level is the full-scale range of the selected
input channel and the resolution is 16-bit.
Below-Low Analog Triggering
In below-low analog triggering, as shown, the trigger signal is
generated when the input analog signal is less than the
Low_Threshold voltage. High_Threshold setting is not used in
this triggering situation.

Above-High Analog Triggering
In above-high analog triggering, as shown, the trigger signal is
generated when the input analog signal exceeds the
High_Threshold voltage. Low_Threshold setting is not used in
this triggering situation
