Osciloscópio portátil de fácil uso

Osciloscópio portátil apresenta uma construção bem robusta, simples de usar. Qualquer coisa, pode usar o manual ou pesquisar no youtube o canal do fabricante que acha videos curtos explicando o uso. Além disso, vem com uma bolsa para guardar o dispositivo. Bom custo benefício pelas funcionalidades que oferece. Mas a tela não é tão grande, mas para pequenas aplicações já é suficiente.
