1Ch,14 Bit,25 MHz,50 MS/s,PCI Express x1, Digitizer, M2i.4038-Exp

The both cards of the M2i.40x8 Express series combine fast A/D data acquistion with the feature to acquire digital data in parallel. With this feature it is possible to either acquire 16 digital bit in parallel from one or more angle decoders or acquiring one or two encoder signals directly by using internal counters. Digital data is either stored continuously and synchronously with the analog data or as an angle marker with each data segment (Option Mutliple Recording needed). The M2i.40xx Express series is best suitable for applications that need high sampling rates as well as a maximum signal dynamic. These boards offer a resolution four times higher than 12 bit boards. On the M2i.40xx every channel has its own amplifier and A/D converter. Each input channel can be adapted to a wide variety of signal sources. This is done by software selecting a matching input range, an input impedance and an individual input offset compensation. The user will easily find a matching solution from the six offered models. These versions are working with sampling rates of 20 MS/s or 50 MS/s and have one, two or four channels. They can also be updated to a multichannel system using the synchronization option. Data is written in the internal 128 MSample up to 1 GSample large memory. All boards of the M2i.40xx series may use the whole installed on-board memory completely for the currently activated number of channels. This memory can also be used as a FIFO buffer. In FIFO mode data can be transferred on-line directly into the PC RAM or to 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.
