IviACPwr Write Arb Waveform [ARB] (G Dataflow)

Last Modified: October 24, 2017

Writes an individual user-defined waveform to the AC power source's memory. If the power source cannot store any more arbitrary waveforms, this VI returns the No Waveforms Available error. If the waveform name already exists, then the VI returns the Duplicate Waveform Name error. If the absolute value of the sum of all waveform data points exceeds 0.001% of the peak to peak amplitude, the VI returns the Waveform DC Offset error.

Waveform Data

Specifies the user-allocated array of the user-defined waveform data to be stored in the AC power source. Default Value: None

datatype_icon

instrument handle

The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options. The handle identifies a particular instrument session.

Default: None

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 ("")

Specifies the waveform name that identifies the arbitrary waveform to write to the AC power source. Default Value: ""

datatype_icon

Waveform Data Buffer Size

Specifies the size of the IVI-C user-allocated waveform data buffer. Default Value: None

datatype_icon

instrument handle out

The instrument handle that you obtain from IviACPwr Initialize or IviACPwr Initialize With Options.

error out

Error information.

The node produces this output according to standard error behavior.

Where This Node Can Run:

Desktop OS: Windows

FPGA: Not supported

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