Left-Hand Circuit Function

In EMI Analyst the Left-Hand Circuit is a circuit consisting of passive electrical components connected to the left-hand end of the Conductors.

In the Conducted Susceptibility and Radiated Susceptibility applications of EMI Analyst the left-hand circuit is positioned at the left-hand end of the Conductors.  The left-hand circuit is comprised of passive electrical components that simulate the impedance of the circuit connected to one end of the conductors of the device under investigation.  The right-hand circuit simulates the circuit at the other end.  The impedance of the left-hand circuit over the frequency range of concern can have a significant effect on conducted susceptibility and radiated susceptibility induced levels.

The left-hand circuit can be constructed to represent circuitry, interconnects, and parasitic elements of the equipment at the left-end of the conductors.  These may include, but are not necessarily limited to semiconductor devices, printed circuit board traces, discrete wiring, and connectors.

The left-hand circuit is created in EMI Analyst using the schematic capture module.  See Schematic Capture for details.
