Gerador de Funções Arbitrárias Rigol DG1022A DG1022U 25MHz

Neste artigo, apresentamos o gerador de funções Rigol da série DG1000, modelo DG1022U, com capacidade de gerar sinais senoidais de até 25MHz com taxa de amostragem de 100MSa/s com até 14 bits de resolução para sinais arbitrários (com definição de ponto a ponto). Além do modelo DG1022U, contamos também com o modelo DG4062 de até 160MHz (série 4000).
