Measuring PCB, Cable and Interconnect Impedance, Dielectric Constant, Velocity Factor, and Lengths

Controlled impedance PCBs often include a measurement “coupon”, which typically includes sample traces, 6 inches long and constructed as part of the printed circuit board panel.  They are measured to assure the PCB stack-up and the accuracy of the PCB transmission lines.
