    I am currently working on a project to measure complex impedance. This is done by introducing a current (~1mA) @ various frequencies (1k to 1M Hz). I would like to float all components in contact with the load. To do this, I would like to use an opto-isolator do to their availability and cheapness. I am having problems locating one for my specific use. Any suggestions?

    Thanks.

    PS - I have decided to not use an isolation transformer do to its funky frequency response.

    I am very concerned that the above statements show a limited understanding of patient safety requirements.

    IEC 60601-1 clearly defines the requirements for contact electrical apparatus

    Look up "patient auxiliary current"
