M4x44xx signal capture card for 3U PXIe format

The M4x.44xx-x4 series card modules use the robust industry standard PXIe interface, with x4-lane Gen2 ultra high-performance technology for transfer speeds in excess of 1.7 Gbytes/sec. The compact dual-width 3U module interface is designed for today's fast PXIe mainframe systems and fits PXIe and PXI hybrid slots Gen 1, 2 or 3. A new generation of monolithic A/D converter is utilised, with a choice of 16 bit resolution at 130 and 250 mega sample/sec, or 14 bits at 500 mega sample/sec. Each input channel has its own carefully designed amplifier section giving synchronous zero phase delay between multiple channels, plus excellent dynamic performance, with ultra low internal noise, excellent SNR (>70bB) and hence precision results. Versatile triggering allows full control of data capture periods. The trigger source can be the input A/D channels, either of two external trigger inputs, any of eight PXI trigger lines, or the PXI star trigger. A 20 MHz bandwidth Butterworth 3rd order input filter can be enabled through software command. Extensive support for programming includes Visual C++, Borland C++, Gnu C++, LabVIEW, MATLAB, Visual Basic, VB.NET, C#, J# and Delphi code.
