Query Arbitrary Waveform Capabilities (G Dataflow)

Last Modified: September 26, 2018

Returns the properties of the waveform generator that are related to creating arbitrary waveforms.

connector_pane_image
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.

datatype_icon

maximum number of waveforms

Maximum number of arbitrary waveforms that the waveform generator allows.

On some waveform generators, this value may vary with remaining onboard memory.

datatype_icon

waveform quantum

Size (number of points) of each waveform, which must be a multiple of a constant quantum value.

This output obtains the quantum value that the waveform generator uses; this means that if the output returns a value of 8, all waveform sizes must be a multiple of 8.

datatype_icon

maximum waveform size

Maximum number of points that the waveform generator allows in a waveform.

On some waveform generators, this value may vary with remaining onboard memory.

datatype_icon

minimum waveform size

Minimum number of points that the waveform generator allows in a waveform.

For some waveform generators, you may need to supply a larger waveform than the value specified by this output.
