    I want to buy a steel vacuum feedthrough which has BNC jacks on that. It said that it is "ground shielded" and i taught it means that ground is not connected to the BNC jacks and they are isolated from ground. Actually I want to have a feedthrough that ground of the BNC is not connected to feedthrough itself and I guess i need a "ground isolated" feedthrough. Can you help me if i am right? and do you know if there is any feedthrogh which is "ground isolated"?
    thanks

    thanks nsaspook,
    All of the feedthrough on K J lesker and others like MPF webpages are mentioned that they are "shield ground" which I am not sure if they are account as "isolated ground" or not? do you know if they are the same terms or not? (isolated or shielded ground)

    If you look near the bottom of this page you will see that some have a grounded shield and some have a floating shield.

    Sorry for my stupid questions, but i have no idea about electronics,

    so floating shield has the same meaning as isolated ground, right?
