Digital I/O makes the most of bandwidth
A novel digital I/O card from Spectrum can be switched between 1, 2, 4, 8 or 16bit acquisition or generation mode, and uses an internal shift register to use the full memory width.
A major drawback when using only a small number of digital channels is the fact that most standard products use at least 8 or even 16bit datapaths This leads to unnecessary overheads and wastes memory and bandwidth if for example only two digital channels are required
Now the 7005 bit stream hardware from Spectrum offers a novel solution.
Simply by using a software command the card can be switched between 1, 2, 4, 8 or 16bit acquisition or generation mode, and using an internal shift register the full memory width is available for use.
As a result, for example, the acquisition of 2bit digital data at 100Msample/s only creates a transfer bandwidth of 25Mbyte/s, and so can be easily stored continuously to hard disk.
The card, available in PCI, PXI and CompactPCI versions, is delivered with drivers and examples for Windows, Linux, C/C++, Delphi, Visual Basic and LabWindows. Request a free brochure from Spectrum Systementwicklung Microelectronic ...
