The diagram shows a coaxial cable connecting a generator with a voltage source, V-tilde sub g, and impedance, Z sub g to a load, Z sub L. The coaxial cable has a longitudinal slit in the outer conductor through which a sliding probe connected to a detector is inserted. The probe moves along the length of the conductor which has a horizontal scale ranging from 10 to 40 centimeters, while the probe tip measures the magnitude and voltage of the line at different lengths.
