Research Points to an Electromagnetic Bazooka
A technique borrowed from acoustics could lead to a super-powerful amplifier of microwave radiation, according to work funded by the French Ministry of Defense. In the article published earlier this year, time reversal is used to generate high power microwave pulses from a low power arbitrary wave generator. Although it was previously thought that creating an EMP of sufficient … [Read more...]
Choosing the Right Chamber for Your Test Requirements
Martin Wiles, Vince Rodriguez, ETS-Lindgren Developments within standards community has led to new chamber validation procedures above 1 GHz and alternative test methods using FARs. INTRODUCTION Anechoic chambers are used today for performing EMC measurements according to a variety of published EMC standards. There are many different fields of application, including … [Read more...]
Surface Scan on IC Level with High Resolution
Measuring of near field above ICs or open DIEs with precisely positioned microprobes is a new tool for engineers to detect and solve EMI levels. Jörg Hacker, Langer EMV-Technik GmbH, Bannewitz, Germany ABSTRACT Today, engineers have less time to develop electronic circuits. The time to market is getting shorter and the requirements on the products are increasing. It means … [Read more...]
Egregious Errors in Electromagnetic Radiation Evaluation
Reasons for widely differing results in commercial radiated emission measurements. MIL-STD-461 RADIATED EMISSION MEASUREMENTS In 1967, the first version of MIL-STD-461 was introduced. Radiated emission measurements were allowed outside of a shielded room but due to the low levels of radiated emission limits, compared to an average ambient, measurements were invariably made … [Read more...]
Radiated Immunity Test System 6 GHz
Teseq’s ITS 6006 consist of an integrated RF signal generator, RF switch and EUT monitoring interfaces. The unit is designed for various radiated EMC applications in the 80 MHz to 6 GHz frequency range. In addition to the generator, the system includes the AM and PM modulators necessary for EMC testing. Other modulators can be connected to the external modulation input of the … [Read more...]
