Snapshot
Test and measurement (T&M) equipment includes oscilloscopes, signal analyzers, spectrum analyzers, network analyzers, multimeters, thermal cameras, power meters, and environmental monitoring instruments. These tools design, validate, and maintain electronic and electrical systems across semiconductor fabs, data centers, telecom networks, aerospace, and factory floors. The global T&M equipment market is approximately $53B in 2026, projected to reach ~$76B by 2032 at a ~6.4% CAGR (compound annual growth rate — the smoothed annual growth over a period). est.
The four tickers span a wide range of T&M relevance. Keysight (KEYS) is the purest play — virtually all revenue is T&M. Teledyne (TDY) mixes imaging sensors, instrumentation, and defense electronics; its Instrumentation segment is ~24% of revenue. Fortive (FTV) retains the Fluke brand (handheld test tools) but spun off its Tektronix oscilloscope/sensing business as Ralliant Corporation (RAL, NYSE) in June 2025 — post-spin Fortive is primarily a workflow-software and healthcare company. Garmin (GRMN) makes GPS devices, fitness wearables, avionics, and marine electronics — not a traditional T&M business; included here as a classification artifact.

T&M is a capital-goods business with lumpy ordering cycles tied to technology transitions (new chip nodes, faster data rates, new wireless standards). Revenue mixes instrument hardware with recurring software, services, and calibration. Growth comes from increasing technology complexity — more advanced chips and networks need more sophisticated test equipment — not from supply tightness.

The product & how money is made
T&M companies sell instruments and software that engineers use to verify electronic designs work correctly and meet specifications. Products fall into three tiers:
- Benchtop instruments — oscilloscopes (visualize electrical signals over time), signal generators, power supplies, spectrum analyzers. ~$1K for basic units to $500K+ for high-bandwidth real-time oscilloscopes.
- System-level solutions — automated test equipment (ATE) for semiconductor production lines, network test platforms for 5G/800G validation, wafer-level probe stations. $1M–$10M+ per system, typically bundled with custom software.
- Handheld/field instruments — multimeters, clamp meters, thermal imagers, insulation testers for electricians and maintenance technicians. $100–$5,000. This is Fluke's (Fortive) core market.
Revenue streams
- Hardware sales (majority): one-time instrument purchases. Customers upgrade when new technology standards arrive (PCIe 6.0, 800G Ethernet, Wi-Fi 7), creating cyclicality tied to the standard-generation cadence.
- Software & subscriptions (growing): Keysight reported ~37% of FY2025 revenue from software and services, with 29% annual recurring revenue (ARR — subscription-like revenue that renews each year). Includes design simulation (PathWave, EDA tools) and software-defined instrument features.
- Services: calibration (mandatory in regulated industries like aerospace/defense), repair, training. Steady repeat revenue.
- Aftermarket: probes, adapters, accessories. Small per-unit, high margin.
Gross margins are high because instruments are precision-engineered, low-volume products with significant IP. Keysight: 64–65%. Teledyne: ~43% (blended across segments including lower-margin government work). Fluke-type handheld tools: 50–60% est..

Demand
Contracted / visible demand
T&M companies generally do not disclose multi-year backlogs like defense contractors. Orders ship within weeks to months. Best visibility comes from order rates:
- Keysight FY2025 (ending Oct 2025): full-year orders ~$5.4B vs revenue $5.38B — book-to-bill ~1.0×. Q4 orders were $1,533M, up 14% YoY. Q1 FY2026 revenue guidance of $1,530–$1,550M implies ~19% growth, though roughly half from three acquisitions (Spirent, Synopsys Optical, Ansys PowerArtist) contributing ~$375M expected FY2026 revenue. orders
- Ralliant (Tektronix + sensing, spun from FTV Jun 2025): defense backlog exceeded $1B as of Q1 2026. Q1 2026 total revenue $535M beat $515M consensus. Full-year guidance raised to $2.185B–$2.245B revenue and $2.53–$2.69 adjusted EPS. backlog
- Teledyne: no disclosed backlog figure. FY2025 revenue grew 7.9% to $6.12B, with Aerospace & Defense Electronics surging 36% to $1.06B. est.

Forecast demand drivers
- AI / data center buildout: validating 800G and 1.6T optical links, PCIe 6.0/7.0, and high-bandwidth memory (HBM) in AI accelerators requires new test equipment generations. Keysight's Commercial Communications segment grew 9% in Q2 FY2025, attributed to "AI-related investment." est.
- Semiconductor complexity: chiplet architectures, advanced packaging (CoWoS, fan-out), and 2nm/3nm process nodes create new test points. Chip capex is expanding at TSMC, Intel, and Samsung. est.
- 5G/6G wireless: 5G Advanced deployments continue; early 6G R&D drives RF/mmWave test demand. The 2020–2023 5G ramp cycle is maturing in developed markets.
- Aerospace & defense: Teledyne A&D Electronics grew 36% in FY2025. Ralliant defense backlog exceeded $1B. Global defense budgets rising broadly.
- Automotive (headwind): EV and ADAS test demand exists but the auto cycle is weak. Ralliant cited "a slowdown in automotive in Western Europe and mainland China." Keysight's Electronic Industrial segment saw automotive and energy declines.
- Cyclicality: Keysight revenue dropped 9% in FY2024 before rebounding 8% in FY2025. T&M orders track customers' R&D and capex budgets, which swing with macro and technology cycles.

Supply
Capacity
T&M instruments are not capacity-constrained like semiconductors or power equipment. These are precision products manufactured in moderate volumes:
- Keysight manufactures in the US (Santa Rosa CA, Colorado Springs), Malaysia, Singapore, Japan, Germany, China. Designs custom measurement ASICs in-house. Production lead times are weeks to a few months.
- Teledyne operates ~125 sites globally. Its Digital Imaging segment (52% of revenue) manufactures specialized sensors and cameras — somewhat more constrained due to infrared and X-ray detector fabrication.
- Fortive/Fluke makes handheld instruments in Everett WA and internationally. Higher-volume than benchtop (millions of multimeters per year). est.
- Garmin manufactures in Taiwan (owned factories), US, UK. Consumer-electronics volumes (tens of millions of GPS/wearable units).
Bottleneck
The binding constraint is R&D — the ability to design instruments that keep pace with next-generation technology standards. When a new standard arrives (800G Ethernet, PCIe 7.0, 6G), the company with a ready test solution captures the design win and customer relationship for that cycle. Keysight spent ~$750M/year on R&D in FY2024 (~15% of revenue). Teledyne spent $317M (5.2%). This R&D intensity is the real barrier to entry.
Component shortages caused T&M lead time extensions during 2021–2022 but normalized by mid-2023. No major supply constraints exist today.

The gap
Unlike power generation or semiconductor fabrication, T&M has no structural demand-supply gap. Manufacturers can build instruments roughly as fast as customers order them. Pricing power comes from technology leadership and switching costs, not shortage.
- Pricing direction: stable to modestly up. Instruments sell on technology differentiation. When a company has the only solution for a new standard (e.g., Keysight's 1.6T Ethernet test platform), it charges a premium until competitors catch up. Average selling prices trend up over time as each generation is more complex.
- Competitive moat is R&D, not capacity. Keysight and Rohde & Schwarz (private, German) dominate high-end RF and signal analysis. Tektronix (now Ralliant) leads oscilloscopes. A new entrant would need years and billions in R&D plus calibration/service infrastructure.
- Cyclical reversal risk: in FY2024 Keysight's orders fell 3% and revenue dropped 9% as customers cut capex. T&M vendors cannot smooth these swings — they follow their customers' R&D budgets.
Demand grows at ~GDP+ rates (~6% CAGR est.). Supply can keep up. Competitive advantage lies in technology and customer lock-in rather than supply scarcity.

What to deep-dive next
- Keysight acquisition integration: $1.7B spent on Spirent, Synopsys Optical, Ansys PowerArtist in FY2025. Expected ~$375M FY2026 revenue, >$100M synergies. Integration timeline is the near-term earnings swing factor.
- Keysight software mix: 37% software/services, 29% ARR. Trajectory of ARR growth determines whether the model is shifting from cyclical hardware to recurring subscription.
- Ralliant (RAL) as cheapest T&M entity: ~3.3× revenue with $1B+ defense backlog, vs. KEYS at 11×. T&M segment was down 15% YoY in Q2-2025 (auto weakness) but improving sequentially.
- AI test demand quantification: what share of Keysight revenue is directly AI-related (800G/1.6T, HBM, AI accelerator validation)? Sensitivity to AI capex pullback.
- Automotive recovery timing: both Keysight and Ralliant flagged automotive as a headwind. EV investment resumption would flip this to tailwind.
- Fortive post-spin identity: Fluke economics are embedded in IOS alongside non-T&M workflow software. Clean Fluke-only financials require segment detail from future filings.
