CS114: The Test That Exposes Cable and Grounding Myths

CS114 is often the most punishing test because it bypasses enclosure shielding entirely. RF current is injected directly onto cables, forcing the design to rely on filtering, shield termination, and grounding integrity. Designs that lean too heavily on enclosure shielding frequently fail CS114. Cable entry points, not metal boxes, determine success here. Poor terminations and high-impedance grounds are exposed instantly.
