NI-TClk Synchronization

niTClk Initiate

Initiates the acquisition and/or generation sessions specified, taking into consideration any special requirements needed for synchronization.

For example, the session exporting the TClk-synchronized start trigger is initiated after all the sessions that import the TClk-synchronized start trigger.

niTClk Initiate.vi

sessions is an array of session references that are being synchronized.

You obtain session references from the instrument driver by using <driver name> Get Session Reference VI, where <driver name> is the name of the instrument driver—for example, the niScope Get Session Reference VI.

error in describes error conditions that occur before this VI or function runs.

	status is TRUE (X) if an error occurred before this VI or function ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI or function ran. The default is FALSE. If status is TRUE, this VI propagates the error and does not do anything else.
	code is the error or warning code. The default is 0. If status is TRUE, code is a negative error code. If status is FALSE, code is 0 or a warning code.
	source identifies where an error occurred. The source string includes the name of the VI that produced the error and often offers additional information about the error.

sessions out passes the array of session references to the next VI.

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, it describes the error status that this VI or function produces.

	status is TRUE (X) if an error occurred or FALSE (checkmark) to indicate a warning or that no error occurred.
	code is the error or warning code. If status is TRUE, code is a nonzero error code. If status is FALSE, code is 0 or a warning code.
	source identifies where and why an error occurred. The source string includes the name of the VI that produced the error and often offers additional information about the error. The LabVIEW Simple Error Handler VI and the LabVIEW General Error Handler VI use the source string to deliver messages that may help you to troubleshoot your application.
