Configures common properties for window triggering.
A window trigger occurs when a signal enters or leaves a window you specify with high level or low level.
The method used to couple the trigger signal.
Name | Value | Description |
---|---|---|
AC | 0 | Couples the trigger signal with an AC current. |
DC | 1 | Couples the trigger signal with a DC current. |
HF Reject | 3 | Couples the trigger signal with a high frequency reject filter. |
LF Reject | 4 | Couples the trigger signal with a low frequency reject filter. |
AC Plus HF Reject | 1001 | Couples the trigger signal with an AC current and a high frequency reject filter. |
Default: DC
Specifies whether the trigger should occur when the signal is entering or leaving a window.
Handle that identifies the NI-SCOPE instrument session as previously allocated by Initialize With Options .
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 source you want the digitizer to monitor for a trigger.
Name | Description |
---|---|
Channel 0 | Monitors Channel 0 for a trigger signal. |
Channel 1 | Monitors Channel 1 for a trigger signal. |
Channel 2 | Monitors Channel 2 for a trigger signal. |
Channel 3 | Monitors Channel 3 for a trigger signal. |
Channel 4 | Monitors Channel 4 for a trigger signal. |
Channel 5 | Monitors Channel 5 for a trigger signal. |
Channel 6 | Monitors Channel 6 for a trigger signal. |
Channel 7 | Monitors Channel 7 for a trigger signal. |
External TRIG | Monitors an external trigger input for a trigger signal. |
Default: Channel 0
The voltage threshold for the digitizer to use for low triggering.
The voltage threshold for the digitizer to use for high triggering.
The length of time the digitizer waits after detecting a trigger before enabling NI-SCOPE to detect another trigger.
Default: 0.00
The length of time the digitizer waits after it receives the trigger to start acquiring data.
Reference to the NI-SCOPE instrument session to pass to the next node in the program.
Error information.
The node produces this output according to standard error behavior.
Standard Error Behavior

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.
When you initiate an acquisition, the trigger system operates in the following manner:
You specify configuration parameters such as the trigger source and trigger delay with each Configure Trigger instance. Additionally, you can adjust the amount of pretrigger and posttrigger samples using reference position in Configure Horizontal Timing . The default is half the record length.
For multirecord acquisitions, all records after the first record are started based on the setting of the Advance Trigger Source property. The default value is immediate.
