Set Arbitrary Waveform Next Write Position

Set Arbitrary Waveform Next Write Position

Configures the start position to use for writing a waveform before calling Write Arbitrary Waveform.

This node allows you to write to arbitrary locations within the waveform. These settings apply only to the next write to the waveform specified by the name input of Allocate Arbitrary Waveform or Write Arbitrary Waveform. Subsequent writes to that waveform begin where the last write ended, unless this node is called again.

Inputs/Outputs

session in

Instrument session obtained from Initialize With Options.

error in

Error conditions that occur before this node runs.

The node responds to this input according to standard error behavior.

Standard Error Behavior

Default value: No error

relative to

Reference position in the waveform.

The position and offset together determine where to start loading data into the waveform.

Start of Waveform	0	The reference position is relative to the start of the waveform.
Current Position	1	The reference position is relative to the current position.

offset

Offset from the relative to input at which to start loading the data into the waveform.

name

Name of the waveform.

This string is case-insensitive and alphanumeric, and it cannot use reserved words.

session out

Reference to your instrument session passed to the next node.

error out

Error information.

The node produces this output according to standard error behavior.
