The 9 models of the M4i.22xx PCI Express (PCIe) series high-speed digitizer are designed for the ultra fast and high quality data acquisition. Each of the input channels has its own A/D converter and its own programmable input amplifier. This allows to record signals simultaneously on 2 channels with 2.5 GS/s and on 4 channels with 1.25 GS/s without any phase delay between them. The extremely large on-board memory allows long time recording even with the highest sampling rates. All boards of the M4i.22xx series may use the whole installed on-board memory for the currently activated number of channels. A FIFO mode is also integrated on the board. This allows the acquisition of data continuously for online processing or for data storage to hard disk.
