Rather than relying on high-power attenuators to reduce the input power level to the measurement equipment, the power measurement kit employs a low-loss 30-dB directional coupler rated for use from 0.8 to 2.2 GHz to channel a reduced-amplitude signal from the base station to the measurement equipment. The kit also included a set of Type N coaxial attenuators for use with the coupler and a Type N coaxial termination rated... READ THE ENTIRE POST HERE.
