PCI-DAS1602/16 User's Guide Functional Details Analog outputs The two high-speed 16-bit dual analog outputs are updated via an on-board FIFO and REP OUTSW commands, and provide a 100 kHz maximum update rate. Output ranges are individually configurable with software for ±10 V and ±5 V, 0 to 10 V and 0 to 5 V. The D/A outputs provide rated accuracy to ±5 mA, and are short circuit protected (25 mA limit). The analog outputs are cleared to 0 V on power up or reset.
Chapter 4 Calibrating the PCI-DAS1602/16 The PCI-DAS1602/16 is equipped with software auto calibration. The InstaCal software makes gain and offset corrections to the board using on-board digital potentiometers and trim D/A converters. No user intervention or external equipment is required. The PCI-DAS1602/16 is shipped fully-calibrated from the factory. All adjustments are made via 8-bit calibration DACs or 7-bit digital potentiometers that are referenced to an onboard factory calibrated standard.
PCI-DAS1602/16 User's Guide Calibrating the PCI-DAS1602/16 Analog output calibration The analog output circuits are calibrated for both gain and offset. Offset adjustments for the analog outputs are made in the output buffer section. The tuning range of this adjustment allows for maximum DAC and output buffer offsets. Gain calibration of the analog outputs is performed via DAC reference adjustments. The analog output calibration system is shown in Figure 6.
