niTClk Synchronize

Synchronizes the TClk signals on the given sessions. After the niTClk Synchronize VI executes, TClk signals from all sessions are synchronized.

Note Before using this NI-TClk VI, verify that your system is configured as specified in PXI Trigger Lines and RTSI Lines.

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.

minimum T clock period is the minimal period of TClk, expressed in seconds. Supported values are between 0.0 and 0.050 s (50 ms). Minimal period for a single chassis/PC is 200 ns. If the specified value is less than 200 ns, NI-TClk automatically coerces minimum T clock period to 200 ns. For multichassis synchronization, adjust this value to account for propagation delays through the various devices and cables.

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.
