M3i.3240 converter card
Spectrum introduces the M3i.3240, a fast monolithic 12-bit A/D converter card.
Compared to 8-bit digitisers, this card is claimed to have 16 times higher resolution and an SNR of 63dB at 1V range.
The complete series consists of four different versions ranging from 250MS/s to 500MS/s with one or two synchronous channels available as PCI/PCI-X and PCI Express version.
The M3i.32xx series is suitable for a range of application areas, especially high-energy physics, research and development, radar, spectroscopy and laser applications.
The configurable A/D amplifier stage consists of a 50ohm terminated path with a bandwidth of 250MHz and a second, high impedance path with a bandwidth greater than 125MHz.
Six input ranges between 200mV and 10V can be software selected.
Each channel has a programmable AC/DC coupling and a selectable low pass filter to optimise noise figures.
The card comes as a standard with 128MSample and can be equipped with up to 2GSample of on-board memory to cope with the large amounts of data.
Using the full memory option it is possible to acquire more than four seconds of data with 500MS/s.
The M3i.32xx is delivered with Windows 2000/XP/XP64/Vista/Vista64 and Linux 32/64 bit drivers and is already tested with Windows 7.
Delivery also includes a set of programming examples and a basic version of the latest SBench 6 software, which has been optimised for handling GBytes of acquired data.
The driver supports all M3i cards as well as all M2i cards to allow hardware upgrading for existing applications.
A set of standard programming examples is provided to illustrate the board's main signal capture functions.
Extensive support includes Visual C++, Borland C++, Gnu C++, Visual Basic, VB.Net, C#, J# and Delphi code.
As an alternative, drivers for Labview, Matlab and Agilent VEE are available.
