Para fonte de tensão ou corrente auxiliar, dispomos da fonte de alimentação programável Rigol 831A com três canais (8V/5A e 30V/2A) com proteção OVP e OCP. A mesma apresenta precisão básica de tensão de 0,01% + 2mV e de corrente 0,01% + 250uA. É possível analisar potência gerada e o equipamento pode ser programado via USB.
