Source Form

Every active circuit is a potential source of emitted electromagnetic interference, i.e., active circuits produce conducted emissions and radiated emissions.  EMI Analyst characterizes active circuits using its voltage and current waveforms, and its stray capacitance to chassis or earth ground.

The Source form allows the user to specify properties of time domain voltage and current waveforms for active circuitry in an EMI Analyst emissions analysis.  EMI Analyst uses the voltage and current waveforms to calculate common mode current, thereby fully characterizing both differential mode and common mode characteristics of the circuit. 

From the time domain waveforms, the Source form calculates the corresponding frequency domain spectrum.  Thus, each voltage waveform has a corresponding voltage spectrum, each current waveform has a corresponding current spectrum, and each common mode current waveform has a corresponding common mode current spectrum.
