Test Setup for ESD Pre-certification & Compliance Testing

A ground reference plane shall be provided on the floor of the laboratory. The EUT shall be connected to the grounding system and arranged and connected according to its installation specific cations. A distance of 1 m minimum shall be provided between the EUT and any metallic structure. The discharge return cable of the test generator shall be connected to the ground reference plane, and this connection shall be of low impedance.

In cases where the length of the cable exceeds the length necessary to apply the discharges to the selected points, the excess length shall be placed non-inductively off the ground reference plane and shall not come closer than 0.2 m to other conductive parts in the test set-up.

Edition 3 Updates Coming Soon. In the meantime feel free to contact us.

• ESD Simulator Gun
• GP: Ground Reference Plane (Aluminum or Sheet Metal)
• HCP: Horizontal Plane (Aluminum or Sheet Metal)
• VCP: Vertical Coupling Plane (Aluminum or Sheet Metal)
• 470 kOhm Resistor Cables to mount from HCP/VCP to GP
• Insulation Material (Polyvinyl Chloride preferred material)
• LISN or other Isolation Transformer (Optional)

Measurement and Evaluation of SATA Cables

Ground reference plane: A copper or aluminum sheet of 0.25 mm minimum thickness: other materials may be used but they shall have at least 0.65 mm minimum thickness. The minimum size is 1 m2. The exact size depends on the EUT. It shall project beyond the EUT or coupling plane by at least 0.5 m on all sides. It shall be connected to the protective earth.

Coupling planes: These planes shall be constructed from the same material and thickness as that of the ground reference plane and shall be connected to the ground reference plane via a cable with a 470kΩ resistor located at each end.
