Calibration
Due to the nature of the electronic circuitry they use, the analog-to-digital and digital-to-analog modules are subject to a slight dispersion of the values they output or measure, as compared to the theoretical values.
To overcome this, the modules are factory-calibrated before being installed on the customer system. This calibration process is used to determine gain and offset parameter values to ensure that the module operates within the prescribed and acceptable range of values, typically with a maximum of ±20 mV around the expected value.
The gain and offset parameters obtained during the calibration process are stored in an EEPROM on the module. They are accessed at power up by the FPGA of the system to which the module is connected, and used during simulation to adjust the output or input values of the modules.
