instrument handle

The instrument handle that you obtain from the IviFgen Initialize or IviFgen 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

Sample Clock Source

Pass the sample clock source you want the function generator to use. The driver sets the IviFgen Sample Clock Source [SC] property to this value. The value you specify determines the clock used for the waveform generation. If you want to set this parameter to IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_EXTERNAL (1), you must first set the arbitrary sample rate to the corresponding frequency of the external sample clock. You can use the IviFgen Configure Sample Rate [ARB] Node or set the IviFgen Sample Rate [ARB] property to configure the arbitrary sample rate.

Defined Values

IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_INTERNAL (0) - Use the internal sample clock.

IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_EXTERNAL (1) - Use an external sample clock

Default: IVIFGEN_VAL_SAMPLE_CLOCK_SOURCE_INTERNAL (0) - Use the internal sample clock

instrument handle out

The instrument handle that you obtain from the IviFgen Initialize or IviFgen 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.
