Keynote Presentation – Managing Energy Flow in High Speed Circuit Boards Using Field Theory
Overview: We are presently stretching the limits of circuit theory to explain how circuit boards work. Further progress will require going back to basics for some new tools. These new tools involve fields and the movement of energy. The use of fields usually means using mathematics. When waveforms are step functions, there is no simple mathematics. Using simple explanations, a new world can be constructed that describes how step waves really work.
Going back purely to field theory will not necessarily provide the insight needed to improve circuit board designs. The important thing is the movement of energy, not the movement of voltage. The fact that these new ideas are simple and non-mathematical needs to be stressed. We need the mathematics to build the bridges to a new world, but once there, it is not all that complicated. It’s like driving on the other side of the road. It takes experience and time. This viewpoint is the only way that fast logic can be mastered. Old habits must yield. Manufacturers who follow this concept when designing their boards will have a huge competitive advantage over those who require multiple board spins to get it right.

PRODUCT DEMO – The R&S Amplifier Portfolio for EMC
Overview: The Rohde & Schwarz amplifier portfolio is well suited for EMC applications with best in industry ability to generate more field strength for a given output power. The R&S ‘P1dB advantage’ will be presented, detailing the importance of properly comparing amplifier output power in the specs sheets. R&S amplifiers are designed to deliver full rated power into a 6:1 VSWR yielding higher power at frequencies of severe antenna mismatch. The combination of the gain flatness across the band with the proprietary leveling algorithms in the R&S EMC32 EMC SW yields the fastest leveling performance in the industry. The combination of higher P1dB across the band, ability to drive 6:1 VSWR at full power, and intelligent leveling algorithms are just some of the reasons for the explosive growth of the R&S amplifier portfolio.

How to Resolve Desense Problems of Wireless Devices Using Fast Very-Near-Field Testing
Overview: Wireless devices often have an extremely sensitive receiver connected to their antennas improve range and reduce power consumption. Even low power noise created by the device in the same band as the receiver it can degrade the overall performance of the device. This effect is called desense and it can occur through direct conducted means or through energy radiated and received through the antenna.
The fundamental source of the noise can be anything in the device including harmonics of clocks, RF signals, power supply, digital lines and because of the extreme sensitivity of the receivers even extremely low level sources of noise can be a problem. The integration of cameras, memory, Ethernet and hard drives into devices creates a large number of potential sources of noise so desense testing and mitigation is a must-do for modern devices.
EMSCAN EMxpert is the tool to help locate the source of interference, understand the mechanism of coupling, plan changes and verify it has been corrected. The EMxpert makes extremely sensitive very-near-field measurements of radiated emissions to get an “emissions map” of a PCB in “real-time”. This map allow designers to locate the source of noise related to desense as well as EMI and EMC problems early in the design cycle thus saving time and cost.
This webinar will discuss very-near-field measurements. Practical tips for measuring wireless devices and a demonstration of an actual “real-time” EMxpert will be shown.
Speaker: Ruska Patton, Director of Product Management
Ruska Patton is responsible for the evolution of EMSCAN’s real-time very-near-field measurement solutions. Having started with EMSCAN as Design Engineer and then Manager of the Design Group, Mr. Patton now leads the development of new EMSCAN solutions from concept through to successful products in market. Mr. Patton has authored academic papers, presented seminars and holds several patents related to near-field scanning.
