NTS Offers Expanded EMI Testing in Its NJ Laboratory
National Technical Systems has announced that its Tinton Falls, NJ laboratory is now equipped to offer high-level EMI testing for electronics and avionics. The lab’s new capability simulates high intensity radar sweeps encountered in hostile combat areas and in final approaches to civilian airports. The expansion includes the installation of a new shielded room, sophisticated … [Read more...]
Enhanced Test System Targets Emissions Testing from 9 kHz to 30 MHz
A newly released version of GAUSS Instruments’ “TDEMI” test systems carries out emissions testing from 9 kHz to 30 MHz. The original version, released earlier this year, handled the frequency range of 150 kHz to 1 GHz. With the new “TDEMI30M” a quasi-peak measurement in Band A or Band B can take as little as 12 seconds. The “TDEMI” measurement system from GAUSS Instruments … [Read more...]
Radio Operators Oppose Proposed Change to Disturbance Limits of CISPR 22
Recently there has been a flurry of activity opposing the proposed change to the disturbance limits of CISPR 22. Objections focus on proposed Power Line Telecommunications (PLT) disturbance limits, which would be relaxed by 18 dB. These disturbance limits for Power Line Telecommunications (PLT) systems are defined by the standard CISPR 22 and its European equivalent EN 55022 … [Read more...]
New EMC Testing Facility Seeks to Boost Retailers’ Product Confidence
A new EMC testing facility has been launched by UK-based TÜV Product Service. This is a unique “spot check” testing facility for retailers, who can now determine if the electronic products they offer comply with existing standards and laws. Specifically, the testing will confirm whether household electrical items such as TVs, camcorders, and game consoles will interfere with … [Read more...]
TÜV Rheinland and TÜV SÜD Withdraw Current Merger Application
The management boards of TÜV Rheinland and TÜV SÜD have withdrawn their merger application from Germany’s Federal Cartel Office. Company officials have determined that the initial proposal would not have met current anti-trust requirements in Germany. Both companies plan to reapply for a merger with a new business solution that meets Germany’s strict anti-trust requirements. … [Read more...]
