m2p6566-x4 eight channel arbitrary wavefrom generator card for the PCI express bus. Image with introductory video link describing dynamic performance, operating modes and software interface

The M2p.65xx-x4 series multi-channel arbitrary waveform generator (AWG) cards uses the high speed Gen2 4-lane PCI express interface. The combination of large on-board memory and ultra fast data upload to the card allows a short or long and complex signal to be generated. The PCIe interface and compact half length PCB are designed to be compatible to many computer and chassis combinations. The latest D/A converter design is utilised and available in two speeds, 40 or 125 mega samples per second. A wide range of speeds up to these limits can be set from software with a fine granularity of 1Hz. Updates are simultaneous and D/A resolution high at 16 bits. This results in an exceptional combination of speed and resolution without the penalty of low signal amplitude. Using the Star-Hub option this card can be precisely synchronised to other Spectrum M2p.65xx cards to provide an increased number of channels. Available in 1, 2, 4 or 8 channel versions, up to 16 cards can be connected using the Star-Hub to provide 128 channels!

Versatile Windows / Linux drivers provide a means of programming the AWG in text code, MATLAB, LabVIEW and LabWindowsCVI. Whilst this card series uses the latest technology, they are still software compatible with the drivers from earlier Spectrum waveform generator cards. Hence existing customers can use the same software they developed for an earlier Spectrum M2i AWG card with just a few code tweaks. Extensive support for text programming includes Visual C++, Borland C++, Gnu C++, LabVIEW, MATLAB, Visual Basic, VB.NET, C#, J# and Delphi code.

Require even greater AWG speed? M4i.66xx-x8 series can provide this!

†Bandwidth depends also on the programmable filter cut-off frequency setting. The slower 40MS/s models share the same 70 MHz filter as the faster model for a fast rise and fall time on square waves. Switching the filter cut-off to a lower frequency (a simple command using the driver software) may yield better results for a sine wave.

The high voltage output versions of the M2p AWG card require the space of one neighbouring card slot for the heatsink.
