Description

technical field [0001] The invention relates to the technical field of electrostatic discharge testing, in particular to an automatic transmission line pulse testing system. Background technique [0002] Integrated circuits are generally more susceptible to being damaged or destroyed by electrostatic discharge (ESD). The transmission line pulse (TLP) test is a main test method for verifying the anti-static discharge (ESD) design of integrated circuits. This technology tests the response characteristics of integrated circuits to high-power short pulses to evaluate their ESD protection capability. [0003] The existing TLP test system technical solution is to charge the transmission line by outputting a certain voltage through a high-voltage source. After charging, the transmission line discharges the device under test (DUT) through the attenuator and the rise time filter, and the voltage probe and current probe of the oscilloscope collect The voltage applied to the device u...
