Signal Integrity Design Validation: Why PCB Structures Must Be Measured, Not Assumed

Signal Integrity Design Validation: Why PCB Structures Must Be Measured, Not Assumed

At GHz speeds, PCB traces are no longer passive wires — they define signal behavior. Here's how vector network analysis makes that visible, measurable, and fixable.
