What EMtest does

EM TEST is a brand of AMETEK CTS (Certified Testing Solutions), a division of AMETEK Inc. (NYSE: AME), that designs and manufactures electromagnetic compatibility (EMC) test and measurement equipment. Founded in 1987 and headquartered in Reinach, Switzerland, with 101-250 employees, the company focuses on hardware used to verify that electronic and electrical products meet EMC regulatory and OEM specifications. Its primary end market is the automotive industry (with specific capabilities around LV 124 and LV 148 supply-voltage standards and battery simulation), alongside aerospace and defense, telecommunications, medical devices, general electrical/electronic products, and component manufacturers.

The product portfolio spans more than 60 distinct lines organized around transient immunity and emissions testing; electrostatic discharge (ESD) simulators up to 30 kV; one-, three-, and four-quadrant battery simulators for automotive power-electronics testing; harmonics and flicker analyzers and power sources; programmable AC/DC power sources (single and three phase); transient surge, burst, telecom surge, ring-wave, and damped-oscillatory generators (including compact 5 kV and 7 kV units); magnetic field generators and antennas; RF immunity test systems and solid-state RF power amplifiers covering sub-1 GHz to sub-8 GHz bands; RF coupling/decoupling networks in common-mode (AF, M, S, T, CAN variants) and differential-mode configurations per IEC/EN 61000-4-19 and 61000-4-31; RF probes and clamps; and test environments including GTEM cells, TEM cells, reverberation chambers, and striplines. Embedded device software lets operators select a standard and run tests automatically with integrated report generation. Equipment is built around piece-by-piece component inspection, full QA traceability, and long-duration burn-in testing, with standards expertise originating from participation in national and international EMC research groups and standards committees.

EM TEST generates revenue primarily through quote-based sales of capital equipment to enterprise customers, with pricing not publicly disclosed. Distribution is executed via direct field sales through AMETEK CTS's worldwide sales and service offices, regional representatives, and a Where to Buy locator, supplemented by a Bergkamen, Germany service center that delivers calibration, upgrades, repair, and training. Marketing reaches engineering audiences through technical papers, application notes, EMC Best Practice webinars, the EMC On-Air podcast, a video library, and a newsletter, all under the unified AMETEK CTS brand umbrella.
