TekBox TBESDT1 ESD Target

The TBESDT1 ESD-Target is a current sensing transducer to verify ESD-Simulators. It is used to take measurements compliant with IEC 61000-4-2 up to 4 GHz.

ESD generated from a person touching a product can disrupt the operation of electronic systems. A typical human-body ESD event creates a high-current discharge into the product. The resulting current pulse may amount to several amperes at a very high leading edge with a rise time of less than 1 ns. 

Testing for immunity from electrostatic discharge (ESD) is critical when designing products in order to comply with worldwide EMC standards. The standards specify the shape and timing of the current pulse from an ESD simulated pulse that is injected into the equipment being tested. It is important to verify that the ESD simulator produces a current pulse with the correct shape and rise time by using a calibrated ESD target and a high-bandwidth oscilloscope.  To check an ESD simulator’s output, it is necessary to measure the waveform of the resulting current across a low-impedance, high-frequency resistive shunt (ESD Target) connected to ground. This target simulates a real-life ESD discharge. The complete test setup also requires low-loss cables, attenuators, and a high-quality oscilloscope.
