Configures common properties for hysteresis triggering. This kind of trigger specifies an additional value, specified in the hysteresis parameter, that a signal must pass through before a trigger can occur. This additional value acts as a buffer zone that keeps noise from triggering an acquisition.

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 trigger slope —

    trigger slope specifies either a rising edge or a falling edge to trigger the digitizer.

    Refer to the Trigger Slope 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 trigger level —

    trigger level specifies the voltage threshold for the trigger.

    Default Value: 0.0 V

  • cdbl.png hysteresis —

    hysteresis specifies, in volts, the size of the hysteresis window on either side of the trigger level. The digitizer triggers when the trigger signal passes through the hysteresis value you specify with this parameter, has the slope you specify with the trigger slope, and passes through the trigger level.

    Default Value: 0.05 V

    Valid Values

    Positive trigger slope 0 <= Hysteresis <= Trigger Level + (Vertical Range / 2) - Vertical Offset
    Negative trigger slope 0 <= Hysteresis <= (Vertical Range / 2) + Vertical Offset - Trigger Level
  • 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.
