16 synchronous A/D channels with 500 kS/s on one PCI/cPCI cardThe new 47xx card series from Spectrum, the specialist company for fast PC instruments, allows the simultaneous data acquisition of up to 16 channels on each card. There are in total 15 different versions available which differ in the number of channels (8 or 16), the sampling rate (100 kS/s up to 500 kS/s) and the card type (PCI, PXI/cPCI 3U, cPCI 6U).
Each channel has its own programmable amplifier with 8 input ranges between ±50 mV and ±10 V and its own ADC with 16 bit resolution. In contrast to the common multiplex cards the 47xx cards from Spectrum offer full sampling rate of 500 kS/s independent whether one channel is active or all 16. This fully synchronous design also minimizes crosstalk between the channels.
Using the Star-Hub option up to 16 cards can be synchronized in one system giving a total of 256 fully synchronous channels each with 16 bit resolution and 500 kS/s sampling rate. Each of the channels can be trigger source for the complete system by connecting the trigger sources by OR/AND conjunction. Besides the common standard trigger modes like level and edge or window these cards also offer a real slope (spike) trigger as well as individual pulsewidth triggers for each channel. This may per example be used to monitor signal failures simultaneously on each channel when doing cable testing.
The cards are equipped with a standard memory of 32 MSamples (PCI version) or 8 MSamples (PXI and cPCI version). The memory is used completely for data buffering allowing continuously streaming of data to the PC for further calculations there.
The cards are delivered with drivers for Windows and Linux as well as extended examples for C/C++, LabWindows, Delphi and Visual Basic. The software SBench suitable for Laboratory use is also included in the delivery free of charge. Support of LabVIEW, MATLAB, DASYLab or Agilent VEE is available as an option.
The M2i.47xx card series is available in small quantities now and is going into serial production beginning of 2007. When doing deliveries Spectrum is able to listen to individual customer requests and can do modifications or extensions for small series or even for single cards.
