Test & measurement
Test and measurement covers the instruments, automated test equipment and calibration services used by engineers and manufacturers to verify electronic, mechanical and material performance. The customer base spans semiconductor fabs, aerospace and defence primes, telecommunications equipment vendors, automotive electronics, electric vehicle and battery manufacturers, and electronics contract manufacturers. The two largest categories are general-purpose electronic measurement (oscilloscopes, signal analysers, network analysers) and automated test equipment for semiconductor production. Annual industry revenue sits in the high-$20B range across the major sub-categories.
The sector spans general-purpose electronic test, semiconductor automated test equipment, environmental and EMC test, materials and mechanical test, calibration services, and test software and automation.
Revenue comes from one-off instrument sales, recurring calibration and service contracts on installed bases, software subscriptions for test automation and data analysis, semiconductor test handler consumables, and project-based qualification work.

How test & measurement companies monetize?
Test and measurement companies monetize through instrument sales, recurring service and calibration, and semiconductor ATE capital sales.
Instrument sales
Capital sales of oscilloscopes, signal analysers, multimeters, network analysers and material testers. The anchor revenue line for Keysight, Rohde & Schwarz, Tektronix and Ametek.
Service & calibration
Annual calibration, recurring maintenance and repair contracts on installed instruments. High-margin and predictable; the cleanest recurring line in the sector.
Software subscriptions
Per-seat licences for test automation, signal analysis and lab management tools. Keysight PathWave, NI TestStand and Tektronix's TekScope sit here.
ATE for semiconductors
Capital-cycle-sensitive sales of automated test handlers and probers to semiconductor fabs. Teradyne (NASDAQ: TER) and Advantest are the two-player oligopoly that dominate this line.
Materials & consumables
Probe cards, sockets and consumables that follow ATE installations. Cohu and FormFactor are the reference names; recurring revenue that scales with the installed base.
Project services
Bespoke qualification and certification engineering for aerospace, defence and telecoms customers. Lower margin than instrument sales but supports relationships and pull-through.

Test & measurement market segments
Test and measurement spans general-purpose electronic test, semiconductor automated test equipment, and calibration services.
General-purpose electronic test
Oscilloscopes, signal generators, signal analysers, vector network analysers and multimeters used across electronics R&D and production. Keysight (NYSE: KEYS), Rohde & Schwarz, Tektronix (Fortive-owned) and Anritsu lead.
Semiconductor automated test equipment
Production test systems and probers used by foundries, fabless and OSAT companies. Teradyne and Advantest hold over 85% of the ATE market combined; Cohu and FormFactor sell handlers and probe cards into the same customers.
Environmental & EMC test
Climatic chambers, vibration tables and EMC chambers used by automotive, aerospace and defence customers. Esstech, Weiss Technik (Schunk) and Espec dominate the chamber side; Rohde & Schwarz and ETS-Lindgren lead EMC.
Materials & mechanical test
Tensile, hardness, fatigue and impact testers, and the supporting metrology. Used by aerospace, energy, civils and medical device customers. Instron (Illinois Tool Works), Zwick Roell, MTS Systems (now Amphenol) and Buehler are the established names.
Calibration services
ISO 17025-accredited calibration providers running multi-site labs that recalibrate instruments on rolling schedules. Trescal, Transcat (NASDAQ: TRNS) and Fortive's Tektronix Service are the larger pure-plays.
Test software & automation
Software platforms for test orchestration, data management and ATE programming. NI TestStand (Emerson-owned after the 2023 acquisition), Keysight PathWave and the data-platforms category led by yieldHUB and ProteanTecs sit here.

Key test & measurement KPIs to track
Revenue growth, gross margin, book-to-bill and backlog are the metrics investors track in test and measurement.
| KPI | Definition |
|---|---|
| Revenue growth | Year-on-year revenue change. Reads tightly to the semiconductor capex cycle for ATE players and to broader industrial R&D budgets for general-purpose test. |
| Gross margin | Separates instrument-and-software businesses (55-65%) from project-services-heavy environmental and materials businesses (30-45%). One of the cleanest profitability reads in industrial tech. |
| Book-to-bill | Orders received divided by orders shipped in the period. The leading indicator the listed players (Teradyne, Advantest, Keysight) publish to flag the next quarter's revenue. |
| Installed base | Active instruments in the field. Drives calibration, service and software revenue. |
| Recurring revenue % | Share of revenue from service, calibration and software. The metric Keysight and Fortive have been growing to deserve higher multiples. |
| ARR | Annual recurring revenue from test software and managed-service contracts. Standard for software-led parts of the stack and for the Trescal-style calibration roll-ups. |
| Operating margin | Earnings on revenue. The Keysight, Teradyne and Fortive benchmark for industrial software-leaning test (20-25%) versus mid-teens for the more service-heavy peers. |
| Backlog | Signed but undelivered orders. Critical for Teradyne and Advantest with multi-quarter lead times on tester platforms. |

Key test & measurement market trends
The Emerson-NI mega-deal, the HBM and AI accelerator test cycle and EV and battery test capex are reshaping test and measurement right now.
Emerson-NI mega-deal
Emerson Electric closed its $8.2B acquisition of National Instruments in October 2023, the largest test and measurement M&A on record. The combination gives Emerson a software-led automated-test platform alongside its process automation business and reshaped the competitive landscape for Keysight and Fortive. Dated October 2023.
HBM and AI accelerator test cycle
Advantest and Teradyne captured a sharp upcycle in 2024-25 as Nvidia, AMD and the hyperscalers ramped HBM3e and CoWoS-packaged AI accelerators. Test intensity per die has roughly doubled relative to traditional logic, supporting elevated tester ASPs and book-to-bill ratios. Dated April 2025.
Keysight-Spirent acquisition
Keysight closed its $1.5B acquisition of Spirent Communications in 2024 after Viavi Solutions abandoned its competing bid. The deal consolidates network and 5G test and extends Keysight into telecoms service-assurance. Dated November 2024.
EV and battery test capex
EV powertrain and battery cell manufacturers (CATL, LG Energy Solution, BYD, Tesla, Ford, GM, VW) are buying environmental chambers, climatic test cells and battery cyclers in volume. Weiss Technik, ESPEC and Maccor reported multi-quarter backlog growth through 2024 driven by this cycle. Dated July 2024.
Defence and aerospace test reshoring
The US DoD and European primes (BAE, Airbus Defence, Rheinmetall) have ramped qualification budgets for Ukraine-related munitions and air defence. Keysight, Rohde & Schwarz and Anritsu have all cited defence as a top growth driver in 2024-25. Dated February 2025.
Data analytics and yield management
proteanTecs (raised $50M Series C in 2024 led by Koch and KDT), yieldHUB and PDF Solutions are pulling tester data into ML platforms that flag yield issues earlier in the production cycle. Keysight, NI and Advantest have all signed partnerships in this layer. Dated September 2024.
