The 2 models of the MX.20xx series are designed for the fast and high quality data acquisition. Every of the up to four input channels has its own A/D converter and its own programmable input amplifier. This allows to record signals with 8 bit resolution without any phase delay between them. The inputs could be selected to one of seven input ranges by software and could be programmed to compensate an input offset of +/-400% of the input range. The extremely large on-board memory allows long time recording even with highest samplerates. A FIFO mode is also integrated on the board. This allows to record data continuously and to process it in the PC or to store it to hard disk.

Based on the CompactPCI 3U standard the PXI (PCI eXtensions for Instrumentation) enhancement was defined especially for the measurement user. In this specification additional lines for measure ment purposes are defined. There is a high-quality 10 MHz reference clock, as well as a star trigger and a trigger bus. The Spectrum boards support all these features, most notably with the help of the reference clock and the star trigger module for an easy combination of products - in including those from different companies. Since September 2003 Spectrum is a member of the PXI system alliance. The Spectrum PXI cards run in a plain CompactPCI 3U slot as well as in a dedicated PXI 3U slot. If using the MX series in a plain CompactPCI slot the PXI features will not be available.
