4.3 Analog Outputs
Each analog channel is an electrically isolated unit provided with a serial 16 bit
DAC, a precision voltage reference and a voltage and current output stage. To
achieve the desired accuracies, each output is checked during production
testing and the deviations found are stored in the EEPROM of the F-FEM-CON.
The F-FEM-CON software takes these deviations into account and corrects
them (calibration). To achieve optimum accuracy, do not use the voltage output
and the current output of a channel simultaneously.
