check before running.
2.2.3 Grounding Requirement
lAll function modules’ good grounding designs are the basis of reliability and
stability of devices. Also, they are the most important guarantee of lightning
arresting and interference rejection. Therefore, the system must follow this rule.
lCoaxial cable’s outer conductor and isolation layer should keep proper electric
conducting with the metal housing of device.
lGrounding conductor must adopt copper conductor in order to reduce high
frequency impedance, and the grounding wire must be as thick and short as
