This parameter applies to the hardware line designated by TrigLine or TrigLineIndex.
Along with TrigCtl and TrigEdge, it declares the grabber attributes of the trigger line sensed by the channel and aimed at generating the trigger event.
The TrigFilter parameter specifies the time constant of the noise reduction filter of the designated hardware line.
The time constant of the filter is the amount of time the line should be detected at the same logic state before a logic transition be considered.
When insulated I/Os are used, TrigFilter is MEDIUM or STRONG. The value OFF is not allowed.
This parameter applies when acquisition control settings require a hardware trigger or page trigger (all acquisition modes).

MC_InputFilter_OFF |
The noise removal filter is turned off. |
FILTER_10ms |
MC_InputFilter_FILTER_10ms |
A 10 ms filter correctly debounces an input. |
FILTER_100ms |
MC_InputFilter_FILTER_100ms |
A 100 ms filter correctly debounces an input and is very efficient to reject 20/60 Hz perturbation. |
When TrigCtl is set to RELAY, the value OFF is not allowed.
When the triggering and end triggering signals are generated through an I/O line, the values of TrigFilter and EndTrigFilter are the same.
