immunity

Electronic products are designed and tested to a variety of EMC requirements. Although specific requirements and test methods can vary by industry, ESD, transient immunity, RF immunity and RF emissions are evaluated for most products – certainly for all products that require a CE Mark.

Teseq Inc., a leading developer and provider of instrumentation and systems for EMC emission and immunity testing, has expanded its ITS 6006 immunity test system to include the new SW 6012 RF switch option.

In the rush to complete RF immunity testing on schedule, it is not all that unusual to overlook inherent test equipment limitations. While some test equipment characteristics such as power amplifier harmonics are obviously a limiting factor, the broadband characteristics of antennas, directional couplers, power meters and isotropic field probes can hardly be considered a limitation for most applications. However, when used with power amplifiers exhibiting significant harmonic distortion in Immunity test systems, the broadband characteristics of these devices can result in measurement uncertainty and unacceptable errors.
