The inputs are configurable either as 64 single-ended channels or as 32 differential channels, and the input range can be software-selectable as ±10V, ±5V or ±2.5V. Scan rates can be controlled from (a) an internal rate generator, (b) through an external digital input, or (c) by direct software commands. Multiple CPCI-16AI64 boards can be connected together for synchronous scanning. Data is buffered through a 64K-sample FIFO. Internal autocalibration networks permit calibration to be performed without removing the board from the system. Functional Description: The CPCI-16AI64 board is a scanning analog digitizer that performs high-speed sampling and 16-bit A/D conversion of as many as 64 single-ended or 32 differential analog input channels. The resulting 16-bit sampled data is available to the PCI bus through a 64K-Sample FIFO buffer. All operational parameters are software configurable. The analog inputs can be sampled in scans of 4, 8, 16, 32 or 64 single-ended channels, or in scans of 4, 8, 16 or 32 differential channels. The scan rate can be controlled internally up to 75,000 scans per second, or any single channel can be sampled at 300,000 samples per second. A Sync input/output signal can replace Channels 62,63 to permit multiple boards to perform synchronous scanning. All inputs are buffered to avoid the high cross talk and input bias currents common with nonbuffered multiplexers. The internal auto calibration utility uses hardware D/A converters to correct for offset and gain errors in the input signal path, and eliminates the missing codes that are inevitably introduced when software correction methods are used. A selftest switching network routes calibration signals through the input multiplexer to the A/D converter to support internal auto calibration, and permits board integrity to be verified by the host. Auto calibration is performed automatically after reset or upon demand from the PCI bus, and calibrates the offset and gain of the converter to a precision internal reference voltage. 8302A Whitesburg Drive · Huntsville, AL 35802 Phone: (256) 880-8787 or (800) 653-9970 FAX: (256) 880-8788 Input Conn Input Pipelined Analog Inputs Configuration Analog 16-Bit ADC 64 S.E., 32 Diff Switching Multiplexer Calibration Vtest Out Offset/Gain Reference Calibration DAC’S Ext Sync Host Local Conn Controller PCI Interface Adapter Dual Mode Buffer PCI Bus Input Power Power Regulated Converter ±5V, Vdd, Vss LCAI16BD01 Figure 1.
