800s PCB PCB: see polychlorinated biphenyl.
PCB
 in full polychlorinated biphenyl

Any of a class of highly stable organic compounds prepared by the reaction of chlorine with biphenyl, a two-ring compound.
 controlled impedance tester uses time domain reflectometry (TDR TDR - time domain reflectometer ) and features enhanced data logging capabilities, crosstalk measurements and enhanced measurement capability on closely coupled differential traces. Comes with 2, 4 or 8 channels, and supports some automatic impedance testers.
