Digitiser card is a speedy sampler

The GaGe CompuScope 1220 is a digitiser card designed to meet the requirements of scientists and engineers in the fields of ultrasonic testing, sonar and lidar imaging systems.

The new GaGe CompuScope 1220, now available exclusively in the UK from TTi (Thurlby Thandar Instruments), is a digitiser card that has been designed to meet the requirements of scientists and engineers in the fields of ultrasonic testing, sonar and lidar imaging systems.

The card combines the advantages of 12bit resolution with the wide range of externally clocked sampling rates required for the tightly integrated systems found in these areas.

It provides two input channels, 12bit vertical resolution, 20Msample/s simultaneous sampling rate, 10MHz bandwidth on most input ranges, external triggering and external clocking.

Input ranges as low as +/-50mV as well as AC/DC coupling and a choice of 50ohm or 1Mohm impedances are all software-controlled for maximum versatility.

DC accuracy is typically +/-0.5% of full-scale input.

The card can also be equipped with up to 2Gsample of onboard memory.

Up to eight CompuScope 1220 cards can be combined in a master/slave system to provide up to 16 simultaneous input channels.

Unlike other digitisers on the market, the CompuScope 1220 features a wide external clock frequency range: from 20MHz down to 1kHz.

This wide range allows it to be used in applications where the clock frequency can vary based on external inputs.

Completely programming-free operation of the CompuScope 1220 is possible using the established GageScope oscilloscope software, which allows the user to easily set up the digitiser and acquire, view, archive and analyse signals.

Gage also offers software development kits for C/C++, Matlab and the popular LabView environment, with support for Windows 95/98, NT, XP and Windows 2000.
