IviPwrMeter Send Software Trigger [SWT] (G Dataflow)

Last Modified: October 24, 2017

Sends a command to trigger the power meter. Call this node if you pass IVIPWRMETER_VAL_SOFTWARE_TRIG for the IviPwrMeter>>Trigger>>Trigger Source [TRG] property or the Trigger Source parameter of the IviPwrMeter Configure Trigger Source [TRG] node.

Note  

If the IviPwrMeter>>Trigger>>Trigger Source [TRG] is not set to the IVIPWRMETER_VAL_SOFTWARE_TRIG value, this node returns a Trigger Not Software (0xBFFA1001) error.

Note  

This node does not check the instrument status. Typically, you call this node only in a sequence of calls to other low-level driver nodes. The sequence performs one operation. You use the low-level nodes to optimize one or more aspects of interaction with the instrument. If you want to check the instrument status, call the IviPwrMeter Error-Query node at the conclusion of the sequence.

instrument handle out

Instrument handle that you obtain from IviPwrMeter Initialize or IviPwrMeter Initialize With Options. The handle identifies a particular instrument session.

Default: None

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

Many nodes provide an error in input and an error out output so that the node can respond to and communicate errors that occur while code is running. The value of error in specifies whether an error occurred before the node runs. Most nodes respond to values of error in in a standard, predictable way.

error in does not contain an error error in contains an error
If no error occurred before the node runs, the node begins execution normally.

If no error occurs while the node runs, it returns no error. If an error does occur while the node runs, it returns that error information as error out.

If an error occurred before the node runs, the node does not execute. Instead, it returns the error in value as error out.
