| Abstract: | Making use of isolated amplifiers can improve the common mode rejection ratio,protect test equipment and units under test and ensure the safety of operators.The structures and technical specifications for several common used isolated amplifiers,such as transformer coupler,optical coupler and capacitor coupler,are discussed briefly.Especially,the isolated amplifier ISO-124P is introduced.The relative affairs,for example,its features,internal structure,operational principle,usage considerations and skills for adjustment are described.By practical tests,the isolated amplifier has excellent specifications. |
