ESD3000-System
22/66
The ESD transient test is a single event test. The susceptibility of an EUT is strongly influenced by the clock
frequency. With the clock frequency, the information will be transmitted in the EUT or to the auxiliary
equipment within a system. The ESD pulse enters the EUT when no information is being transmitted, the
EUT has a very good immunity to EMC test, whereas the equipment will fail in operation. The existing ESD
testers on the market the discharge cannot be synchronised with the clock frequency. Therefore the number
of shots must be increased up to 100 discharges.
Safety:
ESD3000 is not a toy. It is a professional tool and belongs only in the hand of specialists and appropriately
trained personnel.
The ESD3000 must no be switched „ON“ with the „RUN“ button unless a correctly connected earth or
ground cable is in place.
