Ultra fast digital I/O and pattern generators

The Spectrum M2i cards provide exceptional performance for applications such as telecommunications, optics and semiconductor circuit testing... in fact just about any application that requires high and ultra high speed digital logic in the MHz range. All of the Spectrum 70xx series Digital I/O boards listed below may be used for digital signal generation or capture, with versions capable attaining up to 125M Samples/second. The 70xx series has the ability to generate port wide patterns, however should the requirement be to produce data streams from 1, 2 or 4 channels (for example serial data applications) then special model M2i.7005 is a good choice, as it has a mode that avoids unused bit channels taking up memory space and allows better use of the available bandwidth on he PC bus interface. For pattern generation of more recent logic types Spectrum design engineers have brought about the evolution of the 72xx series. Each 4 bit nibble is fully programmable in the range -2 to 10V, so when combined with a differential output options, many of the newer logic standards including LVDS, LVCMOS and ECL can be well catered for. All Spectrum boards(A/D, D/A and Digital I/O) can be clock and trigger synchronised, plus they have many useful enhancement options to allow pattern and gated triggering, timestamp of triggers and asynchronous I/O for instrument control. These M2i boards are recommended for all new applications but also provided with a software compatibility layer for existing users who have programs developed for the earlier Mi series, which has the feature of providing compact PCI and PXI options. M2i are available in two formats; PCI-Express and PCI-PCI-X.

Up to 4 GBytes of on-board memory, 256 MBytes as standard! PCI-X interface allows more than 200MB/s sustained data rate to PC* Also 100% compatible to PCI 32 bit slots Now available for the latest generation PCI-Express PC bus interface Up to 64 bit wide from one card Synchronisation of up to 16 cards ABA mode available. Go from slow continuous to rapid acquisition on trigger events Pattern triggers, programmable delay, AND and OR combinations Optimised clock section, internal or external clock reference Multiple Recording/Gated Sampling with pre-trigger, post-trigger, low rearm time and time stamp Versatile and wide ranging software support   *PCI-X currently provides best streaming performance, typical range 170 to 245MByte/sec.

This extensive list of cPCI and PXI cards provides industrial users with all the performance and resolution, but in a particularly modular and robust format. PXI is also notable by the fact that synchronisation and triggering wiring is neatly wired across a back plane of a chassis.
