Patent ID: 7821272

Claim:
A method for calibrating transient behaviour of an electrostatic discharge test system comprising: a) operating the electrostatic discharge test system to apply a first electrostatic discharge test pulse to a known first device, wherein the first device has a known first impedance during an electrostatic discharge transient; b) simultaneously capturing first voltage and current waveforms generated in response to the application of the first pulse to the first device; c) operating the electrostatic discharge test system to apply a second electrostatic discharge test pulse to a known second device, wherein the second device has a known second impedance during an electrostatic discharge transient that is different from the first impedance; d) simultaneously capturing second voltage and current waveforms generated in response to the application of the second pulse to the second device; e) based on the first and second voltage and current waveforms and the first and second known impedances, determining calibration data for the transient behaviour of the electrostatic discharge test system, wherein the calibration data represents at least one of i) a transfer function and ii) an impedance of the electrostatic discharge test system; and f) storing the calibration data on a computer-readable storage medium.
