In order to understand the power line channel characterization, the power line impedance analysis measurement system which was designed by calculating the impedance and measuring the magnitude and the phase that was induced a specific frequency to the indoor power line. The power line impedance measurement control system was composed of embedded control which was the NI PXI system. The data acquisition and analysis was accomplished by the LabVIEW graphic engineering program. For the I V measurement an induced signal was used for the - reference power line signal which was designed for the 10dB power amplifier. For the current and voltage detection of the induced signal, it is used a current transformer (Peason Electronics, 2877). Components of an inductor as well as a capacitor are distributed to indoor power line as a result of measurement by the EMI removal filter for electric appliance's power. Especially, the capacitor having frequency ranges from 90KHz to 120KHz used for indoor power line communications are distributed.
