Teseq has introduced an ESD simulation system group that includes the four most commonly used discharge networks.

The NSG 438 simulation system group includes 150pF/330ohm, 150pF/2kohm, 330pF/2kohm and 330pF/330ohm discharge networks.

The NSG 438 ESD simulation system group fulfills many automotive and industry test standard requirements including ISO 10605.

With over 20 optional discharge networks, the simulation system also meets several other industry test standard requirements including IEC, ANSI and SAE.

The NSG 438 contains pre-programmed settings for IEC/EN 61000-4-2 and ISO 10605 to ensure the simulator is set up correctly and the proper discharge network is installed.

The simulator’s built-in ISO calibration self-test feature saves time by eliminating extra calibration and functional measurements prior to starting a test procedure.

In addition, the NSG 438 meets the proposed new requirements indicated by ANSI and IEC, which require a more precise definition of calibration methods and tighter specifications for pulse parameters.

With a wide range of discharge networks and rigid and flexible tips available, the simulator meets diverse applications in the automotive, consumer electronics, telecommunications, medical, aerospace and defence industries.

The NSG 438 features pulse voltages of up to 30kV, which support demanding research and development test procedures to determine immunity limits.

The simulator offers adjustable pulse repetition rate ranges from 0.04s to 300s.

A random generator function is also provided for non-standard interference immunity tests, in which the controlled statistical repetition rate of pulse triggering is programmed in either pulse or time mode.

To enable accurate discharge detection and to eliminate faulty discharge counts over a wider operating voltage range, the NSG 438 contains variable threshold selection.

Useful for long test runs, the counter or present counter is incremented or decremented when a discharge is detected.

In addition, the detection feature can be switched off when testing EUTs with non-conductive surfaces, such as plastic housings.

Users can create and store test conditions in the instrument’s memory, resulting in retrieval of the settings remaining on the menu prior to shutdown as well as saved test conditions.

With a safety interlock, the simulator can only be activated as a result of an intentional action by the user; otherwise it switches off automatically for safety purposes.

The NSG 438 is powered by a high-energy battery pack for prolonged performance.

The group, like the base model, comes with a traceable calibration certificate and two-year warranty.

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.
