New Power Frequency Tester Capable of Long and Short Duration Testing
HAEFELY HIPOTRONICS is proud to announce the launch of the Power Frequency Tester, the MAG 1000. The MAG 1000 is a Power Frequency Tester capable of testing all of IEC 61000-4-8. An internal power supply allows the MAG 1000 to be used without any additional external power supplies. A MAG 1000 can help determine if a nearby magnetic field will influence the operational ability … [Read more...]
Troubleshooting EFT
EFT Phenomenon Recently I tested a medical device for EFT susceptibility. The requirement is that the medical device must be immune to EFT bursts generated per IEC 61000-4-4. Per this standard EFT bursts are applied in four steps. For level 4, steps 1 and 2 are +/-2kV at 5kHz, and steps 3 and 4 are +/-2kV at 100kHz. For each step, these bursts are applied at 300ms interval for … [Read more...]
Mitigating EMI Issues In Servo Motors and Variable Frequency Drives
Servo motors and variable frequency drives are wide-spread in the industry. Industrial automation cannot be imagined without these motors. This article deals with certain EMI-related issues inherent to these motors, specifically high-frequency drive signals. Background Servo motors and VFD are typically comprised of two parts - the motor itself and a controller (also … [Read more...]

Huf Installs In-House Testing Thanks to MVG and AR
(October 25, 2016) The Microwave Vision Group (MVG)’s Partnership with Amplifier Research (AR) has enabled automative component company, Huf North America, to more quickly identify potential Electromagnetic Compatibility (EMC) issues. MVG has built and installed a customized semi-anechoic chamber to allow EMC testing in-house at Huf and meet all the varied required … [Read more...]
Measuring Cable Resonances With A Comb Generator
(October 28, 2016) Cables are one of the key metallic structures on a product that can act as an antenna and couple energy, causing radiated emissions and possible compliance test failures. This has been discussed extensively in the literature on product design for EMI compliance. In many cases, they can resonate at their half-wave frequency and actually amplify any harmonic … [Read more...]
All-In-One Validation Kit Compatible with Any SAR System
ART-Fi has recently announced an all-in-one SAR system validation kit compatible with any Specific Absorption Ratio (SAR) measurement system. Compliance labs must perform system verification prior to SAR testing the wireless technologies a device supports. There is also a need to perform regular validation on their SAR systems depending on the lab’s environmental conditions. … [Read more...]
