Multi-tone testing has many benefits. While the multi-tone methodology was initially implemented to increase the speed of immunity testing, it has been found that this method also improves equipment efficiency, offers greater flexibility to truly test the equipment (EUT) under real world threat conditions, and can be fully compliant to standards.
For years, when discussing high field-strength electromagnetic compatibility (EMC) radiated susceptibility testing, Traveling Wave Tube Amplifier (TWTA) technology has been the only available option for pulsed field generation. Now, there is a very attractive alternative to this technology.
This technical paper provides correlation studies between measured data and multiple field solver technologies, providing multiple references to different types of analyses that include AC frequency domain comparisons for both power integrity and signal integrity. It includes time domain characterization of the results using TDR and noise measurements for both packages and printed circuit boards.
