Sets the DDS start pulse phase voltage to be written to the specified device's non-volatile onboard memory using an external calibration reference.

The value you enter in new voltage is written to the non-volatile onboard memory of the specified device and becomes the new calibration constant if you set action of Close External Calibration to Commit. You must use this function in a session created with Initialize External Calibration.

Note  
  • Use Get DDS Start Pulse Phase Voltage to return the DDS start pulse phase voltage currently stored on the device's onboard memory.
  • This function does not immediately change the DDS start pulse phase voltage. Use the DDS Phase Adjust Voltage property of niSync Properties to immediately adjust the DDS start pulse phase voltage.

instrument handle

The session handle that you obtain from Initialize External Calibration. The handle identifies the device to calibrate.

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

new voltage

The new DDS start pulse phase voltage value, in volts, to write to the non-volatile onboard memory of the instrument you are calibrating.

instrument handle out

The session handle you obtained from Initialize External Calibration. The handle identifies the device you have calibrated.

error out

Error information.

The node produces this output according to standard error behavior.

old voltage

The DDS start pulse phase voltage, in volts, last written to the device's non-volatile onboard memory.
