A programmable system for data acquisition and control
Description
A microprocessor-based system for data acquisition and control is described. The system is able to sort data present at input A under control of data present at input B, at rates up to 10khz and capture time of 3 μsec. It is discussed how to configure the system for pulse height analysis, straight multi-channel operation and a special 'indexed channel' mode useful in pulsed spectroscopy of non-linear effects.

Abstract (Portuguese)
Descreve-se o projeto, teste e operacao de um sistema de controle e aquisicao de dados, baseado em um microprocessador monolitico, capaz de ser utilizado de multiplas maneiras. Entre elas, ilustram-se aplicacoes a analise de amplitude de pulso, multi-canal convencional, e uma forma especial de 'multi-canal indexado' concebido para contornar problemas de flutuacao na intensidade da excitacao em medidas de resposta nao linear. O sistema e capaz de processar dados presentes em uma entrada A, sob controle de dados presentes em uma segundda entrada B, a razoes de ate 10KHz, com tempo de captura de 3 μseg.
