ADC with built-in RAM


Fluctuating analog signals registration over a long period of time, e.g. gas-dynamic laser radiation detecting. Converters ensure analog signal preamplification, transfer constant regulation over the range of 20 dB and analog-to-digit signal conversion on the preamplifier output. Through external start pulse entry, obtained results and preamplifier transfer constant values are being stored in RAM. After write cycle finish, information stored in RAM is transferred to PC via LPT or USB.
