16bit digitisers offer cost-effective options

Digitiser cards use multiple 16bit ADCs for true simultaneous sampling, with maximum sampling rates from 200Ksample/s to 3Msample/s and two-, four- or eight-channel configurations.

Strategic Test Corp has released 12 new digitiser cards in the UF2-4600 series.

Using multiple 16bit ADCs for true simultaneous sampling, the cards are available with a choice of maximum sampling rates from 200Ksample/s to 3Msample/s and two-, four- or eight-channel configurations - enabling the user to select the most cost-effective solution.

32Msample of signal memory is provided as standard, but can be expanded to 2Gsample through a proprietary DIMM module onboard.

As with all UltraFast cards the signals can be recorded to card memory and then offloaded, or continuously streamed at up to 225Mbyte/s to the PC host.

Bob Giblett, President, commented: "During product development special attention was paid to the quality of the input gain section and the A/D convertors".

"This results in very low noise and distortion on all input ranges and achieves effective resolution of up to 14.5 ENOB".

The card supports both single-ended and reduced noise differential input termination, without reduction of channel count.

Each channel contains an independent amplifier that allows the user to program each channel with the best voltage range to match each sensor.

Eight ranges are provided from +/-10V to +/-50mV.

A self-calibration feature ensures the removal of any voltage offsets prior to recording.

Large synchronous systems can be configured with up to 16 cards for 128 simultaneous channels.

Trigger conditions can be set on multiple cards combined with and/or, a feature often used in production test processes.

The cards are supplied with drivers for Microsoft Windows and Linux, with free downloads of future OS version drivers such as Windows Vista.

Drivers for Matlab, LabView, VEE, DasyLab and LabWindows/CVI are optionally available.

The Ultrafast UF2-4600 cards are available immediately and prices range from $3190 for the UF2-4620 two-channel 200Ksample/s card, to $11,990 for the eightchannel 3Msample/s version.

Volume discounts and OEM customisation prices are available on request.
