2Ch,8 Bit,25 MHz,50 MS/s,PCI Express x1, Digitizer, M2i.2020-Exp

The cards of the M2i.20xx Express series are designed for the fast and high quality data acquisition. Each of the up to four input channels has its own A/D converter and its own programmable input amplifier. This allows the recording of signals on all channels with 8 bit resolution without any phase delay between them. The inputs can be selected to one of seven input ranges by software and can be programmed to compensate for an input offset of +/-400% of the input range. All four cards of the M2i.20xx series may use the whole installed on-board memory completely for the currently activated number of channels. A FIFO mode is also integrated on the board.

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.
