4Ch,16 Bit,1.5 MHz,3 MS/s,PCI Express x1, Digitizer, M2i.4651-Exp

The M2i.46xx Express series allows recording of one, two, four or eight channels with sampling rates of 200 kS/s up to 3 MS/s. These cards offer outstanding A/D features both in resolution and speed for PCI/PCI-X and PCI Express. The powerful A/D amplifier section offers 8 different input ranges, programmable offset and a software switching from single-ended to differential inputs without decreasing the number of channels. The enhanced FIFO engine is capable of streaming even 8 channels at a sustained 3 MS/s to memory or hard disk.

In contrast to the parallel PCI buses PCI Express slots contain serial point to point connections. Each connection pair (lane) is able to reach a burst connection speed of 250 MBytes/s. The Spectrum PCI Express cards base on the most commonly used x1 lane slot type. One advantage of the PCI Express technology is the direct connection of each slot allowing a full transfer bandwidth for each single card. On the software side there is no difference between PCI/PCI-X or PCI Express. PCI Express is the bus standard for PC based systems for the next couple of years. Today's State-of-the-art motherboards normally have a couple of PCI Express slots but only one or two PCI-X slots. Spectrum's PCI Express x1 cards can be used in any standard PCI Express slot be it x1, x4, x8 or x16. Only some dedicated PCI Express graphics slots may not work.
