Configures the specified physical channel on an SCXI-1521 module for calibration. Measure calibration input and output points by supplying reference signals to the specified physical channel and measuring the outputs. Use the DAQmx Adjust SCXI Calibration VI to specify each input and output point and adjust calibration constants.

Note The terminal where you can measure module output depends on the configuration of the module in MAX. National Instruments recommends cabling the module to the digitizer so that the output appears on the MCH0± pins of the rear signal connector. Refer to the module user manual for more information on the routing of module output.

Inputs/Outputs

  • cu32.png calhandle in —

    calhandle in is a reference to the calibration session that you created using the DAQmx Initialize External Calibration VI.

  • cdaqmxscale.png physical channel —

    physical channel specifies the physical channel to calibrate.

  • cerrcodeclst.png error in —

    error in describes error conditions that occur before this VI or function runs.

    The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.

  • iu32.png calhandle out —

    calhandle out is a reference to the calibration session. Wire this output to other external calibration VIs.

  • ierrcodeclst.png error out —

    error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, error out describes the error status that this VI or function produces.

    Right-click the error out indicator on the front panel and select Explain Error from the shortcut menu for more information about the error.
