AXOS5 Surge & EFT Testing (includes CCL)

This video includes the generic test setups of the Haefely AXOS5 test system for both combination wave surge testing as well as EFT or burst testing including using the IP4B capacitive coupling clamp (CCL). 

Haefely AXOS Platform Overview

This video provided by Haefely, the manufacturer of the AXOS5 and AXOS8 test systems, provides system information and a brief overview of capabilities and connections on front and back.

Data SheetUser Manual


The Haefely Axos 5 EMI (conducted immunity) test generator for 5kV Surge and EFT with a built-in single phase coupling/decoupling network. This compact Haefely product provides safe and reliable operation by using safety interlock, warning lamp and emergency stop functions helping to ensure safe use.

A major advantage of this Immunity Test Generator is the ability to monitor voltage and current through front of the test system. This allows for effective verification of waveform without need for external attenuator. Take advantage of pro-rated daily rates after the first month and quick delivery!

This Immunity Test Generator is designed for EFT / Burst, Surge, Magnetic Field and AC & DC Dips and Interrupts allowing for a diverse range of applications. This pulse generator is easy to operate with manual and automated test mode and software assisted test preparation. The touch screen provides efficient and effective manipulation of testing criteria to meet or a diverse set of testing needs.

The Axos 5 expandable functionality allows for quick and completely automated testing to EN/IEC 61000-4-4, EN/IEC 61000-4-5 and EN/IEC 61000-4-11 and CE Marking. The unit also includes an integrated single-phase coupling decoupling network (CDN) for EMC testing applications up to 16A. The AXOS unit can either be operated via front panel by large color graphic interface or remotely from the PC for added flexibility.
