Enable Front End (G Dataflow)

Last Modified: June 25, 2018

Enables the RF front end for the given channel. Use this node to toggle the active ATR state.

Rx Tx ATR State
disable disable Idle
disable enable Tx only
enable disable Rx only
enable enable Full duplex
connector_pane_image
datatype_icon

niusrprio session in

Object created by the Open node and used as the session handle for the USRP RIO nodes.

datatype_icon

enable

Signal that enables the device front end.

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

scope

Channel to operate on. Valid options are rx/RF 0, rx/RF 1, tx/RF 0, and tx/RF 1.

datatype_icon

niusrprio session out

niUsrpRio session used in all subsequent USRP RIO host nodes.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

Configuring the Daughterboard

For this node, use the scope input to specify which daughterboard to configure.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

Web Server: Not supported in VIs that run in a web application
