EMI Analyst™ (U.S. Patent # 7,222,033) combines the extensive features of CE Analyst™, RE Analyst™, CS Analyst™, and RS Analyst™ to provide users with cost-effective, accurate EMI compliance predictions for a wide range of circuits and systems.
General
Easy to learn – You don't have to be an EMI expert; bridges the gap between circuit design and electromagnetics.
Easy to use – Models electronic systems using the physical and electrical parameters readily available to the circuit designer.
Powerful – Uses advanced numerical analysis, transmission line theory, and circuit theory, to model a wide range of EMI problems.
Accurate – Accounts for parasitic elements, resonant effects, and ground plane interaction to accurately predict emissions and susceptibility as they will be measured in the EMI laboratory.
Universal
EMI Analyst™ supports EMI requirements from all industries and all regulatory agencies worldwide, including:
All EMI limits, all agencies and custom limits. User definable and fully customizable.
Up to 1000 frequency/amplitude waypoints
1 Hz to 100 GHz
Amps, Volts, dBuA, dBuV, and custom units
Amplitudes from 1E-12 to 1E+12
EMI Noise Sources
Model the EMI characteristics of voltage and current waveforms used in your electrical and electronic circuits. Define nearly any waveform using the eight built-in waveform templates. EMI Analyst™ calculates the frequency spectrum, both differential mode and common mode.
Gated sinusoid
Trapezoid
Double exponential
Damped sinusoid
Inductive switching transient
Pulse-modulated sine
Ringing trapezoid
Piece-wise linear waveform
EMI Filters
Accurately synthesize EMI filtering using the built-in schematic capture program. Choose from ideal and realistic components and fully customize to model the characteristics of components and packaging.
Resistors, inductors, capacitors, ferrite beads
Coupled inductors, differential mode and common mode
LISNs, feed-through capacitors, standard terminations
Wired and printed circuit interconnects
Conductors
Account for loading, coupling, mismatch, and resonant effects of cabling using eight fully configurable conductor configurations. Select length, wire gauge, separation, ground plane, and shield dimensions to match your system interconnects.
Unshielded wire pair
Unshielded wire over ground plane
Shielded single wire
Unshielded wire triple
Unshielded wire pair over ground plane
Shielded single wire over ground plane
Shielded wire pair
Shield wire pair over ground plane
Cable Shields
Calculate shield transfer impedance, the true figure of merit for cable shielding effectiveness, using shield physical parameters, such as:
Number of Strands
Strand Diameters or Wall Thickness
Weave Angle
Strand Material
Optical Coverage
Solid wall and woven wire braid cable shields.
Shield Terminations
Account for shield termination method and its effect on cable shielding effectiveness.
Peripheral Shield Terminations
Wire Pigtail Terminations
Braid Pigtails
Flat Conductor Pigtails
Terminations at one end or both ends
Load Circuits
Take into account the loading and resonant effects of circuitry to which your system is connected by accurately modeling those circuits. Account for the non-linear loading effects of Line Impedance Stabilization Networks required for standardized EMI tests.
Uses built-in schematic capture described above.
Display Results
View predicted calculated results that look just like measured results.
