Acquisition boards speed to high
resolution
The Spectrum M2i.46xx series of 16bit data acquisition boards features sample rates to 3Msample/s and up to eight input channels.
For signal capture applications requiring a combination of ultra-high-speed sampling and resolution, the Spectrum M2i.46xx series of 16bit data acquisition boards features sample rates to 3Msample/s and up to eight input channels Carefully designed to make best use the full dynamic range, great attention has been paid to the quality of the amplifier and the A/D conversion

Acquisition range takes on demanding applications
The Spectrum PCI ultra-high-speed board range is claimed to push forward the boundaries of PC-based data acquisition and waveform generation.
PCI acquisition boards handle fast datastreams
With an aggregate sample rate up to 200Msample/s, the MI30 series of PCI data acquisition boards provides a way to capture the extremely rapid signal events with excellent resolution.
To this end, the effective number of bits (ENOB) exceeds 14.5 on a wide range of speed and offset adjustable gain ranges (eight in all +/-50mV to +/-10V), with very low internal RMS noise levels of just a few microvolts on the higher gain ranges, all helping to ensure that the quality of results is exceptional.
The M2i.46xx provides both single-ended and true (not pseudo) differential inputs, selectable from the software, this means that two channels do not need to be combined to provide a differential capability, so the full number of channels remains, each with its own A/D convertor.
Working with differential channels provides excellent common mode noise rejection enhancing the board's performance and giving best results.

A novel range of PC-Card docking stations enables standard PCI data acquisition hardware to be used in the field with notebook PCs.
Acquisition board runs up to 125Msample/s
The Spectrum Mi70 series has been designed to meet requirements for ultrafast bit capture and generation with speeds up to125Msample/s.
PCI range evolves to cPCI and PXI formats
Spectrum has developed a new, advanced and extensive range of CompactPCI and PXI board products.
A very deep standard memory of 64Mbyte is provided, fixed by socket directly to the board, allowing long capture periods.
This can be upgraded to 4Gbyte if required, a feature to all M2i boards in the range.
Additionally the user can switch to a special FIFO mode, which takes this memory and uses it as a buffer, allowing very efficient real time transfer to PC RAM and HDD.
This specification of 16bit board will operate in PCI and PCI-X slots with 3.V and 5V I/O voltage, hence installation into virtually any PC is possible, or even a full length docking station for use with a notebook PC.
So efficient is the design that data can be processed in real time by a running application, while data transfers simultaneously through the PCI or PCI-X slot interface with a bandwidth easily enough to cope with full 3Msample/s speed capture provided by the M2i.46xx series.
Combine this board with others from the Spectrum range using the trigger and clock synchronisation option and any recent PC will be converted to a powerful multi-channel instrument for signal capture, arbitrary waveform generation and high speed digital I/O.
DataQuest Solutions can provide boards with sampling rates of up to 500Msample/s for all types of requirements.
As with all Spectrum boards, an excellent range of Windows and Linux software driver support (32 and 64bit) is available.
For Linux kernel drivers are offered for many standard distributions such as Suse, Redhat, Fedora or Debian with access to optional driver source code, should the distribution not be included.
For ease of use programming examples are provided for Visual C++.
Borland C++, Gnu C++, Visual Basic and Delphi code, as well as third party package options; LabView, LabWindows, Matlab, VEE, DasyLab or MS Excel.
To complete the versatile offering every board purchased comes with SBench, a menu driven signal capture and analysis package complete with a scope type display and easy access to board programmable options, allowing a working system to be up and running within a few minutes.
What ever your choice DataQuest Solutions will be pleased to provide rapid experienced support should it be required.
Comprehensive details of the full range can be found on the company's website as well as links to literature and pricing requests.
