Abstract :
For pt.6 see ibid. (1990). Through experiments to establish why measured values of the RF emission level from equipment under test differ according to measuring location, it was confirmed that one of the reasons is derived from the instability in the power line impedance characteristic change. Attempts to define the power line impedance above 30-MHz frequency range provide some solutions to help obtaining identical results in EMI (electromagnetic interference) level
