Commit

Commit

Causes a transition to the Committed state. Verifies property values, reserves the waveform generator, and commits the property values to the waveform generator.

If the property values are all valid, the waveform generator hardware configuration is set to match the session configuration. Waveforms, scripts, and sequences can be loaded into memory when the session is in the Committed state.

If any properties are changed, the session transitions back to the Idle state. This node has no effect if the waveform generator is already in the Committed or Generating states and returns a successful status value.

Inputs/Outputs

session in

Handle that identifies your instrument session previously allocated by Initialize With Channels.

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

session out

Reference to your instrument session to wire to the next node.

error out

Error information.

The node produces this output according to standard error behavior.

Standard Error Behavior

Hardware Support

This node does not support the PXI-5404.

Programming Patterns

Calling this node before Initiate Generation is optional but has several benefits:

• Routes are committed, so signals are exported or imported.
• Any Reference Clock and External Clock circuits are phase-locked.
• A subsequent Initiate Generation can run faster because the waveform generator is already configured.
