ANALYZING APPARATUS AND FREQUENCY CONVERTING APPARATUS FOR ANALYZING DETERIORATION IN PERFORMANCE OF REPEATER AND THE REPEATER THEREOF

PURPOSE: An analyzing apparatus and a frequency converting apparatus for analyzing deterioration in performance of a repeater are provided to revolve a test signal through the inside of the repeater and analyze the test signal. CONSTITUTION: A signal receiver receives a test signal within a forward frequency band, and a frequency converting unit(210) converts the test signal within the forward frequency band into the test signal within the backward frequency band. The frequency converting unit performs the conversion operation by using the clock signal generated in the frequency converting unit or the repeater into a reference clock signal. The signal transmitting unit transmits the test signal of the backward frequency to the repeater.
