Microstar Laboratories, Inc. Data Acquisition Processors DAP 5380a

To create affordable, high-channel-count systems that sample inputs simultaneously, choose the DAP 5380a, a mid-range board designed to work well in multiples. Each DAP 5380a has an onboard 233 MHz Intel Pentium processor comes with 128M of DRAM onboard memory offers up to 16 channels per board and can acquire 14-bit data at 800k samples per second on each of 4 channels 625k samples per second on each of 8 channels is compatible with other a-Series boards uses a PCI bus for PC-based platforms transfers data to PC at high rates – up to 3200k samples per second allows fast real-time processing provides 14-bit A/D converter resolution provides input voltage ranges of +/-5 volts or +/-10 volts samples analog inputs at up to 5M samples per second complies with the EMC Directive 89/336/EEC There is one current DAP 5380a model: the DAP 5380a/526. The DAP 5380a model, optimized for high-speed analog input, works well in simultaneous sampling applications. By grouping a number of these boards into a single synchronized system, you can simultaneously sample high-speed inputs in groups. Each DAP 5380a board offers up to 16 channels per board and can acquire 14-bit data. 800k samples per second on each of 4 channels for an aggregate rate of 3.2M samples per second per board 625k samples per second on each of 8 channels for an aggregate rate of 5M samples per second per board So, for example, thirty-two simultaneous input channels, in four groups, can be spread across four synchronized DAP 5380a boards with an aggregate data acquisition rate of 20 million samples per second. The sample application in the box at right shows this configuration. To double the aggregate throughput, upgrade to the DAP 5400a. The DAP 5400a provides you a drop-in upgrade path for your most demanding applications, using the same cabling and Eurocards for termination and expansion. All a-Series Data Acquisition Processor boards share the same basic Channel Architecture. The DAP 5380a has a PCI host interface, and is capable of high-speed data transfers to the host PC. Using bus mastering DMA transfers, the DAP 5380a can transfer data to the host PC at 3200k samples per second.
