Polls an attribute until that attribute becomes true.

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

what to wait for

The attribute to poll.

datatype_icon

polling interval

How long, in seconds, to wait between retries.

datatype_icon

timeout

How long, in seconds, to keep retrying before giving up.

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.

Desktop OS: Windows

FPGA: Not supported

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