PCI-Express cards handle data in large
quantities
Each card can run as a freely programmable signal and test pattern generator, or it can be used via an internal synchronisation option together with any of the other cards from the Spectrum range.
Dataquest Solutions provides an extensive range of PCI-Express cards, which now includes arbitrary waveform generators (AWG) The family of cards is manufactured by Spectrum, and provides 14bit resolution and up to 125Msamples a second waveform update

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.
The AWG family contains 10 different models with one to four synchronous channels and sampling rates of up to 125Msamples a second.
Each card can run as a freely programmable signal and test pattern generator, or it can be used via an internal synchronisation option together with any of the other cards from the Spectrum range, be they signal capture, digital I/O or pattern generators.
It is possible to output any waveform from the on-board memory, which can be up to 4Gbyte.
The whole on-board memory can also be used as a big FIFO buffer allowing to output data continuously for considerable periods from just 1ksample/second to the Mega sample maximum.
Each channel can be individually programmed for offset, gain and filtering.
The output drivers of the card can output a maximum of +/-3V into a 50ohm load, or an output level of +/-10V using the optional amplifier cards.
The single-restart mode allows to repeat a free-programmed waveform on each external trigger event, with a lead-time of four clock cycles between triggers, (just 40ns at 100Msamples a second output rate).
All Spectrum boards are supplied with support for Windows and Linux software environments (32 and 64bit).
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 including LabView, LabWindows, MATLAB, VEE, DASYLab or MS Excel.
SPEasyGenerator is also included, providing a rapid way to generate standard signals from an on-screen virtual panel, not unlike that found on the standard bench top waveform generator - and just as easy to control.
Using simple mouse-clicks on knobs and buttons, the signal shape, frequency, offset, amplitude and filter settings are easily set.
