PCI-DAS6013 and PCI-DAS6014 User's Guide
A similar method is used to calibrate the analog output components (PCI-DAS6014
only). A trim DAC is used to adjust the gain of the DAC. A separate DAC is used to
adjust offset on the final output amplifier. The calibration circuits are duplicated for both
analog outputs (see
Trim DAC
