M4x.22xx GHz signal capture card with 3U PXIe format

The M4x.22xx-x4 series have 1 to 4 A/D channels and a robust industry standard PXIe interface, with x4-lane Gen2 ultra high-performance technology for transfer speeds in excess of 1.7 Gbytes/sec. Capable of signal sampling in the realm of nano seconds and with a wide DC to 1.5 GHz input bandwidth, the M4x.22xx-x4 series uses the very latest in A/D converter and amplifier technology. Excellent dynamic performance and ultra low internal noise provides precision results and there is zero phase delay sampling between multiple channels. Utilising the shared PXIe chassis bus clock system and trigger this synchronisation can be extended to multiple cards. A wide range of input ranges are available including a special range option for small signals, starting at just 40 mV full-scale. Extensive support for programming includes Visual C++, Borland C++, Gnu C++, LabVIEW, MATLAB, Visual Basic, VB.NET, C#, J# and Delphi code.
