Calculates calibration constants pertaining to direct analog path output impedance. During external calibration, you can put the device in different configurations and take measurements of the resulting output voltage across different loads. The configuration data, as well as the measurements, are passed to this VI so that NI-FGEN can calculate the appropriate calibration constants and, when the calibration session is committed, store them in the onboard EEPROM.

Inputs/Outputs

  • cdbl.png Load Impedance —

    Load Impedance specifies the impedance of the load across which the measurement passed in as Measured Voltage Across Load is taken.

  • cu16.png Configuration —

    Configuration specifies the configuration of the device for this stage of calibration.

    Input Value Configuration Setting
    0 NIFGEN_VAL_CAL_CONFIG_DIRECT_PATH_50OHMS
    1 NIFGEN_VAL_CAL_CONFIG_DIRECT_PATH_75OHMS
    2 NIFGEN_VAL_CAL_CONFIG_DIRECT_PATH_DIFFERENTIAL
  • civrn.png Instrument Handle —

    Instrument Handle identifies your instrument session. Instrument Handle is obtained from the niFgen Init Ext Cal VI.

  • cstr.png Channel Name —

    Channel Name specifies the channel that this VI uses.

  • cdbl.png Measured Source Voltage —

    Measured Source Voltage specifies the analog output voltage measured across a very high-impedance load.

  • cerrcodeclst.png error in (no error) —

    error in describes error conditions that occur before this node runs. This input provides standard error in functionality.

    Default value: no error

  • cdbl.png Measured Voltage Across Load —

    Measured Voltage Across Load specifies the analog output voltage measured across the load impedance specified in Load Impedance.

  • iivrn.png Instrument Handle Out —

    Instrument Handle Out passes a reference to your instrument session to the next VI.

  • ierrcodeclst.png error out —

    error out contains error information. This output provides standard error out functionality.
