PCI-DAS1602/12 User's Guide Functional Details Analog inputs The PCI-DAS1602/12 provides eight differential inputs, or 16 single-ended analog inputs. The input mode is software selectable, with no switches or jumpers to set. The board offers a 330 kHz maximum sample rate in single and multi-channel scans at any gain setting. A 1024 sample FIFO assures data taken from the board is transferred into computer memory without the possibility of missed samples.
PCI-DAS1602/12 User's Guide Functional Details Analog outputs The PCI-DAS1602/12 provides two channels of high-speed 12-bit analog output. The analog outputs are updated via an on-board FIFO and REP OUTSW commands and provide a 250 kHz maximum update rate. Software selectable output ranges are 0 to 10 V, 0 to 5 V, ±10 V, and ±5 V. Channels may be set at different ranges.
Chapter 4 Calibrating the PCI-DAS1602/12 The PCI-DAS1602/12 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-DAS1602/12 User's Guide Calibrating the PCI-DAS1602/12 Analog output calibration Analog output circuits are calibrated for offset and gain. Coarse and fine offset adjustments are made in the output buffer section. The tuning range of these adjustments allows for maximum DAC and output buffer offsets. Coarse and fine gain calibration is performed via adjustments to the DAC reference. The analog output calibration system is shown in Figure 6. This circuit is duplicated for both DAC0 and DAC1.
