Configure Arbitrary Waveform (G Dataflow)

Last Modified: May 16, 2018

Configures the properties of the waveform generator that affect arbitrary waveform generation, selecting the arbitrary waveform to produce and setting the gain and offset.

The waveform generator must not be in the Generating state when you call this node.

Programming Patterns

You must set the output mode input of Configure Output Mode to arbitrary waveform before calling this node.

offset

Offset value the waveform generator adds to the arbitrary waveform in volts (V).

When you create an arbitrary waveform, you must first normalize the data points to a range of -1.00 to +1.00. You can use this input to shift the range of the arbitrary waveform.

For example, to configure the output signal to range from 0.00 V to 2.00 V, set offset to 1.00.

gain

Factor by which the waveform generator scales the arbitrary waveforms in the sequence.

When you create an arbitrary waveform, you must first normalize the data points to a range of -1.00 to +1.00. You can use this input to scale the waveform to other ranges. The gain is applied before the offset is added.

For example, to configure the output signal to range from -2.00 V to +2.00 V, set gain to 2.00.

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

channel name

Name of the waveform generator channel that the node uses.

datatype_icon

waveform reference in

Arbitrary waveform to produce.

You can create multiple arbitrary waveforms using Create Waveform, which returns a reference that you use to identify each waveform.

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.

Desktop OS: Windows

FPGA: Not supported

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