Define User Standard Waveform (G Dataflow)

Last Modified: April 28, 2017

Defines a user waveform for either standard function or frequency list output mode.

Programming Patterns

You must set the output mode input of Configure Output Mode to standard function or frequency list before calling this node. To select the waveform, set the waveform input of Configure Standard Waveform or Create Frequency List to user.

connector_pane_image
datatype_icon

channel name

Name of the waveform generator channel that the node uses.

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

waveform size

Size of the waveform in samples.

datatype_icon

waveform data array

Array of data you want to load into the new waveform.

You must normalize the data points in the array to be between -1.00 and +1.00. Use the amplitude input of Configure Standard Waveform to generate different output voltages.

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.
