  • Page 20: Functional Description

    The PCI-DAS64/M1/16 provides 32 fully differential or 64 single-ended analog inputs. The input mode is software selectable, with no switches or jumpers to set. The PCI-DAS64/M1/16 offers a 1 MHz sample rate. The board offers full speed acquisition in single channel scans, and will perform full accuracy multi-channel scans of up to 1.5 MHz, depending on the operating mode.

  • Page 21: Burst Mode

    The board supports simultaneous full speed operation of both the A/D and D/A. Digital I/O The PCI-DAS64/M1/16 provides 32 bits of digital I/O. An 82C55 chip provides 24 bits of CMOS compatible I/O at the board’s 40-pin auxiliary digital connector. Four LSTTL-compatible digital inputs and four outputs are provided on the main 100-pin connector.

  • Page 22: Calibrating The Pci-Das64/M1/16

    Calibrating the PCI-DAS64/M1/16 Overview The PCI-DAS64/M1/16 provides self-calibration of the analog inputs and outputs, eliminating the need for external equipment and user adjustments. All adjustments are made via 8-bit calibration DACs which are referenced to an on-board factory-calibrated standard. The board is fully calibrated at the factory with calibration coefficients stored in nvRAM.

    PCI-DAS64/M1/16 User's Guide Calibrating the PCI-DAS64/M1/16 Table 5-1. A/D calibration frequencies Calibration Frequency (kHz) Min Sampling Frequency (kHz) Max Sampling Frequency (kHz) 0.01 1000 For best results, calibrate the board immediately prior to making your measurements. The high-resolution analog components on the board are somewhat sensitive to temperature and this pre-measurement calibration helps assure your board operates at the same temperature at which it was calibrated.
  • Page 24 PCI-DAS64/M1/16 User's Guide 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.
