Calibrating the PCI-DAS64/M1/16

The analog output circuits are calibrated for gain and offset.

Gain calibration of the analog outputs is performed

via DAC reference adjustments. Offset adjustments for the analog outputs are made in the output buffer section.

The tuning range of this adjustment yields maximum DAC and output buffer offsets.

Analog output calibration is shown in

This circuit is duplicated for both DAC0 and DAC1
