What Teseq AG does

Teseq AG is a Switzerland-headquartered manufacturer of Electromagnetic Compatibility (EMC) test equipment, organized as a brand within AMETEK CTS, a division of AMETEK Inc. (NYSE: AME). The company develops and sells instruments, software, and accessories for immunity and emissions testing, positioning itself as offering the world's most comprehensive range of EMC systems. Its portfolio spans transient immunity and emissions generators, automotive supply voltage variation equipment compliant with LV 124 and LV 148 standards, four-quadrant and one/three-quadrant battery simulators for EV testing, ESD generators (16.5 kV and 30 kV), harmonics and flicker analyzers, programmable AC/DC power sources, RF immunity test systems, coupling/decoupling networks (CDN/CDND), probes and clamps, EMC test antennas (Bilog, horn, loop), and a full range of GTEM/TEM cells, striplines, and reverberation chambers. Solid state RF amplifiers cover frequency bands below 1 GHz, 6 GHz, and 8 GHz.

The company sells into five primary verticals: automotive, industrial electronics, consumer electronics, medical technology, and telecommunications, plus secondary channels of accredited testing laboratories, research institutes, and educational institutions. Its go-to-market is direct enterprise field sales supported by a global sales and service office network, with a dedicated service center in Bergkamen, Germany handling calibration, upgrades, and repairs. Marketing channels include technical papers, application notes, webinars, an EMC On-Air podcast, a video library, the AMETEK CTS LinkedIn presence, and an online product selector tool.

Revenue is generated primarily through one-time equipment sales supplemented by recurring calibration, service, repair, and training revenue streams. Pricing is quote-based and not publicly disclosed. The company cites active participation in international EMC standards committees as a core capability, and its solutions are reportedly deployed in a majority of accredited and certified laboratories worldwide. Teseq operates alongside sister brands EM TEST and Milmega within AMETEK CTS, benefiting from shared global manufacturing and distribution infrastructure.

Direct peers

• Rohde & Schwarz: German-headquartered test and measurement giant with a broad EMC immunity and emissions product portfolio (signal generators, amplifiers, receivers, test chambers) directly competing with Teseq across automotive, industrial, and wireless EMC applications.
• AR RF/Microwave Instrumentation: Specialist manufacturer of RF power amplifiers and EMC test systems directly comparable to Teseq's solid-state amplifier and RF immunity product lines used for radiated immunity testing.
• ETS-Lindgren: Provider of EMC test chambers (anechoic, GTEM/TEM), antennas, and probes that directly competes with Teseq's chamber and antenna portfolio for radiated emissions and immunity test setups.
• HV Technologies: Focused EMC test equipment vendor offering transient, surge, ESD, and conducted immunity generators that compete head-to-head with Teseq's transient generator and automotive EMC product families.

Broad incumbents

• Keysight Technologies: Large diversified electronic test and measurement company whose EMI receivers, signal analyzers, and EMC software solutions overlap with Teseq's emissions measurement and RF immunity offerings, though its portfolio extends well beyond EMC into general electronics T&M.
• Yokogawa Electric: Japanese test and measurement company whose power analyzers, oscilloscopes, and harmonics/flicker instruments overlap with parts of Teseq's programmable power source and harmonics/flicker analyzer portfolio, though Yokogawa's center of gravity is industrial process and power measurement.
• Anritsu: Japanese test and measurement company with spectrum analyzers and signal generators used in EMC emissions testing; comparable as a broad-line T&M incumbent rather than a focused EMC specialist.
• Tektronix (Fortive): Test and measurement vendor (part of Fortive) with oscilloscopes, spectrum analyzers, and signal sources used in EMC labs, overlapping with Teseq's RF measurement and emissions testing toolset though serving a much broader customer base.

Emerging players

• Gauss Instruments: German specialist in real-time EMI receivers and compliance testing solutions for conducted and radiated emissions, directly competing with Teseq's emissions measurement and analysis product lines in a narrower niche.
• MVG (Microwave Vision Group): Provider of antenna measurement and EMC test systems, including compact ranges and chambers, comparable to Teseq's GTEM/TEM cells and reverberation chamber offerings for radiated EMC testing.
