EM5040 Series LISN
Compact Line Impedance Stabilization Network — CISPR 16 / MIL-STD-461 Conducted Emissions Compliance
XGY EM5040 is a family of V-type line impedance stabilization networks designed for conducted disturbance voltage measurement in EMC testing. The series supports R&D debugging, compliance validation, receiver protection, CM/DM analysis, and high-current EMC workflows.
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.
