Function Usage

Selecting the Calibration Input Signal Source

The input signal source is specified by the input parameter. The input signal selection allows the calibration
application to select the signal source from which the channels can be calibrated for a given calibration session.
Prior to calling this function, the daqOpen function should be used to open the device to be calibrated, and the
daqCalSelectCalTable

function should specify which calibration table will be used to perform the

calibration .
