Radiated Emissions
Radiated Emissions Simulation
Radiated emissions refers to electromagnetic noise generated by the equipment under analysis and propagated over the air. Most digital signal carrying conductors have the capability to radiate, given the right conductor dimensions and impedance, and the signal speed and switching characteristics. This digital circuitry, which are not specifically designed to be antennas, are referred to as unintentional radiators.
At Lagwaves, we use 3D full wave simulations and are able to replicate your test environment in our software model. Intricate circuit characteristics are modeled in a transient co-simulation where schematic components can be added. Finally, we can correlate simulation results with measurements by applying receiver bandwidth settings and other model characteristics. We can also partner with you to work on establishing transfer functions between your simulation and measurement setup so that you can maximize utilization of your simulation data.

Inputs Required
When submitting a request to simulate radiated emissions at board (PCB) or system level (boards connected with cables, w or w/o enclosure), the following items are required to be submitted for the evaluation:
-
ECAD of the boards (ODB++, Allegro, IPC-2581, HyperLynx formats)
-
MCAD of the boards and enclosures (STP, IGES, STL, SAT formats)
-
PCB Schematics (pdf format)
-
Cable schematics (pdf format)
-
Radiated emissions standard
-
Specific test requirements (receiver RBW settings, analysis frequency range, customer defined requirements)
-
Equipment setup in measurement chamber (for model accuracy)
