Just want to clarify our terms here. When you "calibrate", is this describing a process where you compare something to a standard value, and then adjust the something into as similar a condition as possible? In the case of an LISN, there are no "adjustable" components available. It seems like when we measure the parameters of an LISN, we simply then declare it good or bad; within the acceptable tolerance or not. I would call this a characterization, not a calibration. Right?
