Experiments and Software Demonstrations
Programme
The aim of the hardware experiments and computer software demonstrations is to show a principles or phenomena, or effects of EMI/EMC as well as measurement and troubleshooting methods.
The presentations are informal and non commercial which will be will be demonstrated in dedicated session on 7 th September 2016 after lunch in specific areas within the conference building and/or EMC lab.
List of experiments ansd software demonstrations will be published soon.

"Remote practical works on transmission lines in the L3-EOLES Bachelor degree" |
This proposal aims to do a live demonstration of remote practical works (available from any Internet connection) build in the framework of a third year Bachelordegree fully online launched at the University of Limoges in 2014.
Two practical works ("Time-domain study of a RG58 cable", "Dispersion analysis of a LC delay line") about transmission lines will be showed. |

"Innovative solution in Power Integrity & Signal Integrity Electromagnetic Analysis for PCB" |
It has become much more important to get higher frequency s-parameters for PCB accurately due to ever increasing data rates. ADS 2016 features a host of new technologies designed to improve accuracy of PCB simulations, including two electromagnetic (EM) software solutions specifically created to help signal and power integrity engineers.
This solution consists in 4 new EM simulators:
- DC IR drop analysis
- AC PDN impedance analysis
- Power plane resonance analysis
- Power-aware signal integrity analysi
In this presentation, you will learn the new innovative pure EM based SIPro and PIPro composite technologies for designing high speed digital boards. SIPro and PIPro provides a cohesive workflow with ADS for signal integrity and power integrity applications.

"Radiated emissions of cables trough shielded enclosure seams and effect of time rise/fall on clock signals" |
This experiment shows a means of measuring leakage of electromagnetic energy through seams of a shielded enclosure to analyse the effects in some test positions around the cover. This cover will be removable and will have 18 threaded fasteners distributed around its periphery.
An oscillator circuit capable of producing a typical periodic clock signal will be put inside the shielded enclosure. The output of the oscillator will be connected to a long twin lead to generate common-mode currents and to investigate their associated radiated emissions.
Next, to study the emissions, a probe will be placed in each defined test positions to measure the potential difference between the cover and the enclosure. Then, it will be used a ferrite common-mode chokes to suppress the common-mode current. Another solution to reduce the common-mode effects is to connect a filter adapter to the long twin lead. Nevertheless, this two methods will increase the rise/fall time of the signal.
Therefore, the final solution could be to use a gasket to shield the seams of the cover and to achieve emissions reduction as using a ferrite common-mode chokes or a filter adapter, but this method does not increase rise/fall times of the generated clock signal.

"DC/DC Converter Measurements and EMC Simulation of Conducted Emission"
| DC/DC converters are common source of conducted emissions. In CST experiment a real Step-down Buck Converter will be presented as an object for both the measurements and 3D-EM simulations.
CST STUDIO SUITE will be use to present the complete simulation workflow including:
- Layout import - materials, ports,lumped elements
- 3D-EM setup - 3D geometry, simulation settings (boundary conditions, mesh)
- Circuit setup - nonlinear components, components to be tuned
The comparison of simulation results with measurement results will be presented. Effects of applying EMI filter and possible layout differences will be discussed as well.

"An EMField Generator - an Integrated Novel Solution for Radiated Immunity Testing, including IEC 61000-4-3" |
In this “live” demonstration in an EMC chamber, attendees will see a novel EMField generator used for an IEC 61000-4-3 fully compliant RF immunity test in the 1 - 6 GHz frequency range at a test level of 3V/m, with 80% AM modulation.
The compact test set up will be reviewed prior to the live demonstration. A comparison will be shown between this novel solution and the traditional approach. The advantages in the simple, novel solution will be contrasted to the
complex, traditional approach to this test that requires larger amplifiers at a greater expense to compensate for the reflected power loss from the load. Power efficiencies with minimal signal loss will be shown in the novel solution.
Attendees will see how the compact novelsolution can be used as a full replacement to the complex traditional set up for testing in accordance with IEC 61000-4-3. |
