Digitiser card designed for scientists and engineers in ultrasonic testing, sonar and lidar imaging systems combines 12-bit resolution with a wide range of externally clocked sampling rates
The 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 12-bit 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, 12-bit vertical resolution, 20MS/s (megasamples per second) 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 50 ohms or one megohm 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 two gigasamples of on-board 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 2000.
