Dear Members,
Generally what is the frequency range for PCB impedance
coupon measurement? Is it possible to measue the impedance of the coupon at a
specific discrete frequency?
For better accuracy is it necessary to have 2 seperate
bands one for USB full speed (12 Mbps) design and another for USB high speed
(480 Mbps) design?
Thanking you all in anticipation
Geetha
