Microstar labs dap 4000A/212 data acquisition board
The DAP 4000a/212 board has the following features
* have an onboard 486 processor
* come with 8MB of DRAM onboard memory
* are compatible with other a-Series boards
* use a PCI bus for PC-based platforms
* transfer data to PC at high rates up to 800k samples per second
* allow real-time processing
* offer low latency 0.2 ms task time quantum for fast response
* increase sampling period resolution to 50 ns
* provide onboard emulation of DSP routines
* sample or update the digital section at up to 800k values per second
* provide 14-bit A/D converter resolution
* provide the same input and output voltage ranges as the DAP 4200a
* sample analog inputs at up to 800k samples per second
* update analog outputs at up to 400k samples per second each
* have expandable analog and digital inputs/outputs
The DAP 4000a has a PCI host interface, and is capable of high speed data transfers to the host PC. Using bus mastering DMA transfers, the DAP4000a can transfer data to the host PC at the maximum sampling rate of 800k samples per second.
Each DAP 4000a model provides 14-bit A/D resolution for its 16 onboard analog inputs, and 12-bit D/A resolution for its 2 onboard analog outputs. The onboard analog input channels sample at an overall 800k samples per second, and the 16 onboard digital input channels sample at an overall rate of 800k words per second. The two onboard analog output channels update at an overall 400k updates per second, and the 16 onboard digital output channels update at an overall 800k words per second.
