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
