niDMM VIs

niDMM Configure Sample Trigger Slope

Sets the Sample Trigger Slope property to either rising edge (positive) or falling edge (negative) polarity.

instrument handle identifies a particular instrument session.

You obtain the instrument handle parameter from niDMM Initialize or niDMM Initialize With Options. The default is None.

Slope specifies the polarity of the trigger signal on which the measurement is triggered for values of either falling edge or rising edge.

NI-DMM sets the Sample Trigger Slope property to this value.

Rising Edge 0 POSITIVE The driver triggers on the rising edge of the trigger signal.
Falling Edge (default) 1 NEGATIVE The driver triggers on the falling edge of the trigger signal.

error in (no error) describes error conditions that occur before this VI runs. If an error occurred before this VI runs, the VI passes the error in value to error out. This VI runs normally only if no error occurs before this VI runs. If an error occurs while this VI runs, it continues and sets its own error status in error out. Use niDMM Error Message 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.

status is TRUE (X) if an error occurred before this VI ran or FALSE (checkmark) to indicate a warning or that no error occurred before this VI ran. The default is FALSE.

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 describes the origin of the error or warning and is, in most cases, the name of the VI that produced the error or warning. The default is an empty string.

instrument handle out returns a handle that you use to identify the instrument in all subsequent instrument driver VI calls.

error out contains error information. If error in indicates that an error occurred before this VI ran, error out contains the same error information. Otherwise, it describes the error status that this VI 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.

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. 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.
