Runs the instrument self-test routine and returns the test results.

For some waveform generators, the hardware is reset after this node runs. If you use this node, your waveform generator may not be in its previously configured state after the node runs.

datatype_icon

session in

Handle that identifies your instrument session previously allocated by Initialize With Channels.

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

session out

Reference to your instrument session to wire to the next node.

datatype_icon

error out

Error information.

The node produces this output according to standard error behavior.

self-test result

Value returned from the waveform generator self-test. A returned value of zero indicates success.

datatype_icon

self-test message

Self-test response string from the waveform generator.
