# IviDownconverter Configure Reference Oscillator [RO] (G Dataflow)

Version:

Configures the reference oscillator.

## instrument handle

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

Default: None

## 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

## reference oscillator source (Internal)

Pass the reference oscillator source used to generate the precise IF output frequency. The driver uses this value to set the IviDownconverter Reference Oscillator Source [RO] property. Valid Values: IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_INTERNAL - Internal reference oscillator. IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_EXTERNAL - External reference oscillator. Default Value: IVIDOWNCONVERTER_VAL_REFERENCE_OSCILLATOR_SOURCE_INTERNAL

## external frequency (10.0e6 Hz)

Pass the frequency of the external signal that is used as reference for internal IF frequency generation. The driver uses this value to set the IviDownconverter Reference Oscillator External Frequency [RO] property. Default Value: 10.0e6 Hz Notes: (1) This value is valid only when IviDownconverter Reference Oscillator Source [RO] is External.

## instrument handle out

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

Default: None

## error out

Error information.

The node produces this output according to standard error behavior.
