See Data Logger Trace 1 Source (Y02).
The scope is triggered by a rising edge at the input to the main scope block. If Data Logger Trigger Source (Y07) is set at its default value of 0.000
then the output of the trigger threshold comparator is 0, and so the scope can be triggered with Data Logger Trigger (Y06). Data Logger Trigger Invert
(Y09) can be used to invert the trigger signal.
If Data Logger Trigger (Y06) = 0, the scope can be triggered based on the level of a parameter defined by Data Logger Trigger Source (Y07) and the
Data Logger Trigger Threshold (Y08). This source operates in the same way as the trace sources and a direct comparison is made between the
actual parameter value and the threshold. Decimal places are ignored. The threshold detector output is 1 when the value from the scope trigger
source is greater than Data Logger Trigger Threshold (Y08). If Data Logger Trigger Source (Y07) = 0.000, or it is used to select a parameter that does
not exist or is non-visible, then the output of the threshold detector is 0.
See Data Logger Trigger Source (Y07).
