Teseq has developed a coupling/decoupling (CDNE) network for emissions testing.

The instrument was designed to adhere to EN 55015, based on CISPR 15 A1 Ed 7, which introduces an independent way of measuring the radio-disturbance characteristics of electrical lighting equipment.

The CDNE range meets the specifications of IEC 61000-4-6 for emission measurement in the frequency range 30 to 300MHz.

Key specifications

  • Offers closer CDN impedance tolerances
  • Emissions-measuring equipment requirements transferred to CISPR 16-1-2 and methods to CISPR 16-2-1
  • Closer tolerances for the asymmetrical impedance
  • The phase angle, symmetrical impedance and internal attenuation are also defined
  • Offers improved reproducibility for current EN 55015 measurements

Teseq — EMC test solutions: combining tradition and experience with dynamic and innovative development 

Teseq is the new name of the Test Systems Division that belonged to the Swiss-based Schaffner Group until it became an independent company after a management buyout in 2006.  

Teseq has retained all of the former Schaffner Division’s management and employees ensuring business continuity, commitment to existing and new customers and a dynamic approach to new product development.  

Teseq also continues to stand for customised client support, proven products and extensive know-how. The company’s focus on its core business — EMC test solutions — will be reinforced by greater attention to innovation in the area of research and development. The streamlined size of the enterprise ensures maximum independence, agility and flexibility.  

Teseq offers standalone products and complete solutions for EMC conducted immunity testing including: ESD generators; harmonics; flicker and power quality test systems. It also provides a complete range of EMC radio frequency test equipment from measuring receivers, power amplifiers and GTEM cells to very powerful software for the automation of EMC test houses.    

Teseq’s extensive knowledge of EMC systems can be found in more than 90 countries worldwide with hundreds of systems installed in applications such as automotive, military, telecoms, commercial and medical.
