DAQmxSetup1520Cal
int32 DAQmxSetup1520Cal (uInt32 calHandle, const char channelNames[], float64 gain);
Purpose
Sets the SCXI-1520 module to the specified gain value. Calibration input/output points can be measured by supplying reference signals to the specified channel and measuring the outputs. Each of these points should be specified using the DAQmxAdjust1520Cal function. This function will also disable sample and hold on the module so that the output can be measured by external devices that cannot supply the appropriate sample and hold timing signals.
|
Note The terminal where module output is measured will depend 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. Please refer to the module user manual for more information on the routing of module output. |
