6.1.1 In order to illustrate that the LISN essentially presents 50Ω impedances between phase and ground and between neutral and ground, use PSPICE to plot the frequency response of the impedance looking into one side of the LISN shown in Fig. P6.1.1 over the conducted emission frequency range of 150 kHz-30 MHz for two cases of impedance seen looking into the power net: (1) short-circuit load and (2) open-circuit load. Determine the values at each end of the frequency band....
