Configures common properties for runt triggering.

A runt trigger occurs when both the leading edge and trailing edge of a pulse cross only one of two trigger thresholds you specify and with a polarity you specify, where the polarity is relative to the threshold crossed.

Note You can add time qualification to trigger on runt pulses that, in addition to meeting your amplitude and polarity criteria, also meet duration criteria. Add time qualification to the runt trigger with the Runt Time Condition, Runt Time Low Limit, and Runt Time High Limit properties. Time qualification is disabled by default.

Inputs/Outputs

  • cu16.png trigger coupling —

    trigger coupling specifies how to couple the trigger signal.

    Refer to the Trigger Coupling property for defined values.

  • ci32.png polarity —

    polarity specifies the polarity of the runt pulses, relative to the runt threshold the pulses cross, that trigger the oscilloscope for runt triggering.

    Refer to the Runt Polarity property for defined values.

  • civrn.png instrument handle —

    instrument handle identifies a particular instrument session.

  • cstr.png trigger source (Channel 0) —

    trigger source passes the source you want the digitizer to monitor for a trigger.

    Default Value: Channel 0

    Refer to the Trigger Source property for defined values.

  • cdbl.png low threshold —

    low threshold specifies, in volts, the lower of two thresholds that bound the vertical range to examine for runt pulses.

    Refer to the Runt Low Threshold property for more information.

  • cdbl.png high threshold —

    high threshold specifies, in volts, the higher of two thresholds that bound the vertical range to examine for runt pulses.

    Refer to the Runt High Threshold property for more information.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

  • cdbl.png trigger holdoff —

    trigger holdoff specifies the length of time the digitizer waits after detecting a trigger before enabling NI-SCOPE to detect another trigger.

    Default Value: 0.0 s

  • cdbl.png trigger delay —

    trigger delay specifies how long the digitizer waits after it receives the trigger to start acquiring data.

    Default Value: 0.0 s

  • iivrn.png instrument handle out —

    instrument handle out has the same value as the instrument handle.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
