同轴电缆，一种通常用来联接天线与接收机或发射机的电缆。电缆由中心导体和外层的屏蔽所组成。
COAXIAL cable, an electrical cable usually connecting an antenna with a receiver or transmitter. The cable has an inner conductor and an outer grounded shield.
使用三同轴电缆时，为了减少电缆泄漏并尽量降低电路的上升时间，可以将内层屏蔽驱动到保护电位。
With triax cable, the inner shield can be driven at guard potential in order to reduce cable leakage and minimize circuit rise times.
