Calculates calibration constants pertaining to the preamplifier gain of the main analog path. During external calibration, you can put the device in different configurations; program different gain, offset, and main DAC values; and take measurements of the resulting output voltages. 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.

  • 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.

  • c1di32.png GainDACValues —

    GainDACValues specifies an array of the values programmed to the gain calibration DAC during this calibration stage.

  • 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

  • c1ddbl.png MeasuredOutputs —

    MeasuredOutputs specifies an array of the analog output voltages measured during this calibration stage.

  • c1di32.png OffsetDACValues —

    OffsetDACValues specifies an array of the values programmed to the offset calibration DAC during this calibration stage.

  • 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.
