Compares the array in requestedOutputs to the array in measuredOutputs and calculates the calibration constants for the output resistance of the specified channel. Refer to the calibration procedure for the device you are calibrating for detailed instructions on the appropriate use of this function. This function can only be called from an external calibration session.

Syntax

ViStatus _VI_FUNC niDCPower_CalAdjustOutputResistance(ViSession vi, ViConstString channelName, ViUInt32 numberOfMeasurements, const ViReal64 requestedOutputs[], const ViReal64 measuredOutputs[])

Remarks

Note

NI-DCPower uses the terms "source" and "output". However, while sinking with electronic loads and SMUs these correspond to "sinking" and "input", respectively.

Note

This function is not supported on all devices. Refer to Supported Functions by Device for more information about supported devices.

Parameters

NameDirectionTypeDescription
vi[in]ViSession

Identifies a particular instrument calibration session. vi is obtained from the niDCPower_InitExtCal function.

channelName[in]ViConstString

Specifies the channel name to which these calibration settings apply. Only one channel at a time can be calibrated.

numberOfMeasurements[in]ViUInt32

Specifies the number of elements in requestedOutputs and measuredOutputs.

requestedOutputs[in]const ViReal64[]

Specifies an array of the output values that were requested in the niDCPower_ConfigureOutputResistance function.

measuredOutputs[in]const ViReal64[]

Specifies an array of the output values measured by an external precision digital multimeter.

Returns

Reports the status of this operation. To obtain a text description of the status code, call niDCPower_error_message. To obtain additional information concerning the error condition, call niDCPower_GetError. The general meaning of the status code is as follows:
