1. A portable nodal impedance analyser, comprising:
an impedance analyser configured with an auto best curve-fit application which automatically selects at least one Voltage value, at least one Source Impedance value, and at least one Frequency value for an at least one sinusoidal stimulus waveform to generate an equivalent circuit and V-I traces in a way that models the V-I Characteristics of components present in a node.
