Stable Impedance for Accurate Conducted Emission Measurement

The EM5040 Series is a family of V-type line impedance stabilization networks designed for conducted emission testing and EMC debugging. These LISNs provide a stable impedance environment for the equipment under test while coupling disturbance signals to external receivers or analyzers for accurate measurement.

The series includes multiple configurations for different workflows. EM5040E provides the standard single-phase LISN function, EM5040A adds a built-in 10 dB limiter and optional 150 kHz high-pass filter, EM5040B adds common-mode and differential-mode separation for advanced debugging, and EM5040C targets high-current, higher-frequency single-line testing for industrial and automotive-related applications.
