Good afternoon all. I had a discussion this morning with a customer regarding the relative merits of DC-based SIR testing vs. the newer impedance spectroscopy, which is AC-based. I know of it and the basic operating theory, but not much more. Is there anyone in the TechNet crowd who has started to use impedance spectroscopy as a research or production tool? Or more to the point, willing to share information on this new tool? I think it is an exciting concept. Thanks for any input.
