Configures the Reference trigger for digital edge triggering.
If the Reference trigger is asserted before the required number of pretrigger samples are acquired, it is ignored. This node is valid only for acquisition sessions.
Error conditions that occur before this node runs.
The node responds to this input according to standard error behavior.
Standard Error Behavior
Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.
Default: No error
The specified edge to detect.
Name | Value | Description |
---|---|---|
Rising edge | 12 | The trigger asserts on the rising edge of the digital signal. |
Falling edge | 13 | The trigger asserts on the falling edge of the digital signal. |
Default: Rising edge
The number of pretrigger samples the device must receive before the Reference trigger is acknowledged.
Default: 500
