This application provides an
electrostatic discharge (ESD) testing
system for an
Ethernet interface, relating to the field of ESD testing. The
system includes: an excitation source device, an
Ethernet interface
simulation device, and a testing device; the
Ethernet interface
simulation device is connected to both the excitation source device and the testing device; the Ethernet interface
simulation device is a
printed circuit board simulating the Ethernet interface of
a domain controller; the excitation source device generates a first current conforming to an ESD waveform and injects this first current into the Ethernet interface simulation device; the testing device acquires the output
voltage of the Ethernet interface simulation device. Compared to related technologies that rely on prototype testing of domain controllers, the method of this application reduces the complexity of ESD testing for the Ethernet interface of
a domain controller.
