Abstract:
1. An electrostatic discharge (ESD) testing system comprising: a measurement chamber to hold a discharge electrode and a target electrode in separation from each other; a first conductive path to supply an ESD pulse to the discharge electrode; a second conductive path to receive a discharge pulse from the target electrode; a transmission line, field-coupled to the second conductive path, to generate a measurement signal in response to the discharge pulse; and means for varying the separation distance between the discharge electrode and the target electrode; wherein the means for varying the separation distance between the discharge electrode and the target electrode can vary the separation distance while the chamber is substantially sealed; and wherein the means for varying the separation distance between the discharge electrode and the target electrode comprises at least one threaded carrier to hold one of the electrodes, the threaded carrier threaded through a wall of the chamber.
