niUSRP Properties (G Dataflow)

Last Modified: April 2, 2018

Gets (reads) or sets (writes) NI-USRP properties.

When you read a property, NI-USRP analyzes the current configuration in order to return the coerced value for that property. Setting a property may transition the session to the Initialized state.

niUSRP in

Reference to the niUSRP session.

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

Active Channel

Specifies the channel name used to access all subsequent properties in this instance of the property node. If the property you want to use is channel-based, you must first select this property and then pass the name of the specific channel. If the property you specify is not channel-based, or you want to set the property on all channels, pass an empty string or omit setting this property.

Enter 0 for the first channel and 1 for the second channel. The order of the IP addresses sets the channel order.

Default: "" (empty string)

niUSRP out

Reference to the niUSRP session.

error out

Error information.

The node produces this output according to standard error behavior.
