Returns the settings for a standard waveform generation.

Instrument Handle In specifies the session created by the Initialize VI. |

error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

Instrument Handle Out is a reference to the instrument. |

Waveform Function indicates the type of waveform.

Frequency indicates the frequency of the waveform. |

Duty Cycle indicates the percentage of time the waveform is in an active state. This value is a number between 0 and 100, where 0 is 0%, and 100 is 100%. Square waveforms support duty cycles between 0% and 100%. Triangle/ramp waveforms support duty cycles between 0% and 100%, where 0% is a ramp up waveform, 100% is a ramp down waveform, and 50% is a triangle waveform. This parameter does not apply to sine waveforms. |

![]() |
Amplitude indicates the peak-to-peak amplitude of the waveform. |

![]() |
DC Offset indicates the DC offset for the waveform. |

error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces. Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
