Abstract
The invention is directed to techniques and mechanisms for measuring transmission loss of a cable comprising the steps of disabling an antenna connected to a second end of the cable, feeding an input signal having an energy level into a first end of the cable for transmission of the input energy toward the second end of the cable, measuring a reflected energy, reflected back toward the first end of the cable from the second end of the cable, and comparing the reflected energy to a input energy to determine a cable loss. Directional couplers may be used to sample the input and reflected energy to be measured. The information derived from the comparison of input and reflected energy measurements can then be used to calibrate a transmitter thereby optimizing performance.
