Waveform digitiser solves make-versus-buy dilemma
The ATS850 is an OEM-friendly PCI-based waveform digitiser that provides 8bit, 50Msample/s sampling on two simultaneous channels with a fully programmable front-end and trigger circuitry
"We are proud to say that not only is the ATS850 the lowest cost product in its class, but it also outperforms waveform digitisers that are more than twice its price", says Muneeb Khalid, President of AlazarTech. One of the major challenges faced by the development team was that the ATS850 had to be priced low enough to justify a buy-versus-build decision by customers who wanted to embed a digitiser in their equipment.

Waveform digitisers reduce waiting time
The ATS460 family of 14bit PCI waveform digitisers is capable of sampling two simultaneous analogue inputs at rates up to 125Msample/s on each channel
This challenge was met by using AlazarTech's acquisition system on programmable chip (ASoPC) technology.
The ATS850 provides independently programmable input ranges from +/-20mV to +/-20V, AC/DC coupling and 50ohm/1Mohm impedance on each of its two channels.
The sampling rate is also programmable from 50Msample/s down to 10Ksample/s.

Users can capture signals from rapidly occurring triggers by using multiple record mode that allows both pre- and post-trigger capability.
A 40bit timestamp allows users to record the occurrence of each trigger event relative to all other triggers in a given session.
The standard model comes with 256Kpoint of acquisition memory per channel.
A high memory model with 16Mpoint per channel will be available in Q1 of 2004.
Acquired data can be transferred to the host PC memory using scatter-gather DMA (bus mastering) that provides transfer rates in excess of 40Mbyte/s even under the Windows operating system.
The ATS850 digitiser is accompanied by ATScope software that allows the user to set up the digitiser, acquire signals and view and store them without writing a single line of programming code or drawing any diagrams.
OEMs can integrate the ATS850 into their own systems very easily using the Windows XP/2000/98SE compatible ATS-SDK software development kit.
This SDK includes sample programs written in C/C++ and Visual Basic.
A LabView VI, called ATS-VI, is also available.
The ATS850-256K is available immediately at a price of $995 (USA) or Eur 895 (elsewhere).
