2.2.3 Grounding Requirement
• All function modules' good grounding designs are the base of reliability and stability
of device. Also, they are the most important guarantee of lightning arresting
and interference rejection. Therefore, system must follow this rule.
• Coaxial cable's outer conductor and isolation layer should keep sound electric
conducting with the metal housing of device.
• Grounding conductor must adopt copper conductor in order to reduce
high frequency impedance, and the grounding wire must be as thick and
