Introduction

Choosing the right instrument starts with a clear overview. The Yokogawa Test&Measurement Products and Services Overview 2026 brings the full portfolio together in one catalog. It covers power measurement, waveform and data acquisition, optical and fiber-optic testing, calibration, signal sources, process recording and handheld tools, plus software, calibration services and expert support.

Each section explains what the product family is for, which models are available and the specifications that matter most. Engineers in R&D, production testing, field service and calibration laboratories can use it to shortlist models quickly before going into the detailed datasheets.

Yokogawa has built precision measurement instruments since 1915, when the company introduced Japan’s first electric meters. Measurement is still its core business.

Precision power measurement

As energy-efficient technology spreads through homes, offices, transportation and industry, engineers have to validate efficiency, performance and safety against evolving international standards. Yokogawa’s WT series covers this, from standby-power testing of household appliances up to multi-motor EV powertrain analysis.

The WT5000 Precision Power Analyzer is Yokogawa’s most accurate power analyzer, with a basic power accuracy of 0.01% of reading + 0.02% of range and a bandwidth of 10 MHz. It holds up to seven swappable input elements and can analyze up to four motors at the same time, which makes it a fit for automotive development, inverter-driven motors and renewable energy. The WT5000 Transformer Version reaches 0.008% and is specified for power factors as low as 0.001, for R&D, production and acceptance testing of power transformers.

The WT1800R offers up to six input elements for three-phase motors and drives, multi-output power supplies and LED lighting. The new WT1500 combines up to four power and four motor channels in a compact 2U rack-mount design, with native CAN/CAN FD output for automated EV powertrain and production test systems. The WT500 is a mid-range analyzer for inverters, drives and transformers. The WT300E is the fifth generation of the world’s bestselling power meter and is used to test white goods, lighting and air conditioning against IEC 62301, Energy Star and SPECpower.

Yokogawa’s European Standards Laboratory is ISO/IEC 17025 accredited (RvA K164) for power calibration. It gives quantifiable confidence in your power measurement system and its results.

ScopeCorders, oscilloscopes and software

ScopeCorders combine the speed of an oscilloscope with the recording time of a data recorder. They capture transient events and trends for up to 50 days, or stream continuously to a PC. The DL950 ScopeCorder samples at up to 200 MS/s on up to 160 synchronized channels, with isolated inputs up to 1000 V. The portable DL350 is battery-powered and A4-sized, made for troubleshooting in the vehicle and in the field. The SL2000 is a PC-based high-speed data acquisition unit that streams data over 10 GbE at up to 10 Gbps. A choice of 22 plug-in modules covers voltage, current, temperature, strain, vibration, logic and CAN/CAN FD/LIN/SENT.

Yokogawa oscilloscopes are known for high channel counts, long memory and optional power and automotive serial bus analysis. The DLM3000 and DLM5000 mixed signal oscilloscopes offer up to 500 MHz, 2.5 GS/s and 4 or 8 channels. The DLM3000HD and DLM5000HD high-definition oscilloscopes add 12-bit resolution, up to 1 Gpoints of memory and IEEE 1588 synchronization with Yokogawa power analyzers.

IS8000 Integrated Measurement Software connects and synchronizes multiple instruments, such as the WT5000, DL950 and DLM5000HD, with an error below 10 µs. The IS8011/IS8012 software handles harmonic and flicker testing to IEC 61000-3-2, -3-3, -3-11 and -3-12. WTViewer, LabVIEW drivers and the TMCTL libraries support analysis and test automation.

Optical spectrum analyzers and fiber-optic test

Photonics is no longer only about telecom. It now plays a role in manufacturing, biology, healthcare and environmental monitoring. With more than 40 years of experience, Yokogawa offers eight optical spectrum analyzers that together cover 350 nm to 5500 nm. The AQ6380 is the highest-performance model, with 5 pm resolution and ±5 pm wavelength accuracy. The AQ6370E is the telecom industry standard. The new AQ6361 is built for telecom and datacom production testing and measures up to 20 times faster than the AQ6370E. The AQ6373E and AQ6374E cover visible light. The AQ6375E reaches into the short-wave infrared, and the AQ6376E and AQ6377E extend into the mid-infrared up to 5500 nm for environmental and medical sensing. The AQ6151 optical wavelength meter and the AQ7420 high-resolution reflectometer complete the range.

For installing and maintaining fiber networks, from FTTH to long-haul, Yokogawa offers the AQ7290 and AQ7280 OTDRs, the AQ1210 series, handheld light sources, optical loss test sets and Ethernet testers. The AQ2200 and AQ2300 platforms support optical component and transceiver manufacturing.

Calibrators, standards and signal sources

The 2553A and 2560A precision DC calibrators, the 2558A AC voltage/current standard and the LS3300 AC power calibrator serve calibration laboratories and production lines. The GS200 DC voltage/current source, the GS610 source measure unit and the GS820 multi-channel source measure unit generate and measure precise signals for evaluating electronic components. A battery simulator version is available.

Data acquisition, recorders and handheld tools

SMARTDAC+ GX and GP paperless recorders and the GM data logging system record process data such as temperature, pressure and flow. They can be expanded up to 420 channels and also integrate with WT power analyzers. The range is completed by TY series digital multimeters, handheld calibrators and the MT300 digital manometer.
