Abstract
Calibration method for calibrating transient behavior of a TLP test system. The system comprises a TLP generator, probe needles, nominally impedance matched transmission lines and measurement equipment, connected between the transmission lines and the TLP generator, for detecting transient behavior of a device under test by simultaneously capturing voltage and current waveforms as a result of generated pulses. The calibration method comprises (a) applying the TLP test system on an open and capturing first voltage and current waveforms; (b) applying the TLP test system on a calibration element having a known finite impedance and a known transient response and capturing second voltage and current waveforms; (c) transforming the captured first and second current and voltage waveforms to the frequency domain, and (d) determining calibration data for the transient behavior of the TLP test system on the basis of the transformed first and second voltage and current waveforms.
