IviRFSigGen Get LF Generator Name [LF] (G Dataflow)

Last Modified: September 7, 2018

Returns the specific driver defined LF generator source name that corresponds to the one-based index specified by the Index parameter. If you pass in a value for the Index parameter that is less than one or greater than the value of the IviRFSigGen>>LF Generator Extended Properties>>LF Generator Count property, the node returns an empty string in the Name parameter and returns the Invalid Value error.

Note  

For an instrument with only one LF generator source, i.e. the IviRFSigGen>>LF Generator Extended Properties>>LF Generator Count property is one, the driver may return an empty string.

instrument handle

The instrument handle that you obtain from the IviRFSigGen Initialize Node or IviRFSigGen Initialize With Options Node. The handle identifies a particular instrument session.

Default: None

datatype_icon

error in

Error conditions that occur before this node runs.

The node responds to this input 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.

Default: No error

datatype_icon

index (0)

The index of the analog modulation source whose name is returned. The value must be greater than or equal to one and less than or equal to IviRFSigGen>>LF Generator>>LF Generator Count. Note: Zero is not a legal value. Default Value: 0

instrument handle out

The instrument handle that you obtain from the IviRFSigGen Initialize Node or IviRFSigGen Initialize With Options Node. The handle identifies a particular instrument session.

Default: None

error out

Error information.

The node produces this output according to standard error behavior.
