Yokogawa

Yokogawa's power measurement lineup spans from compact, single-phase meters to high-channel-count, multi-phase analyzers. Single-phase models like the Yokogawa WT210, Yokogawa WT310, and Yokogawa WT310E feature a compact footprint and basic voltage/current accuracies of 0.1%. These meters are designed for dedicated single-phase (1P2W) testing of standby power, consumption, and efficiency. For three-phase electrical systems, the Yokogawa WT230 provides a two- or three-element configuration in a compact benchtop housing, supporting wiring configurations up to 3P4W.\n\nFor advanced research and engineering evaluation of complex multi-phase systems, high-performance analyzers are recommended. The Yokogawa WT3000 and Yokogawa WT1600 support up to 4 and 6 input elements respectively, allowing detailed efficiency measurements on multi-phase inverters. The WT3000 offers ultra-high accuracy with a basic power reading accuracy of 0.02%. For capturing fast, fluctuating voltage and current waveforms, the Yokogawa PZ4000 precision power analyzer features 12-bit A/D converters with a high-speed sampling rate of up to 5 MS/s and a 2 MHz measurement bandwidth.

Yokogawa provides instruments for both spectral characterization and physical fiber testing. For field maintenance and installation, the Yokogawa AQ7270 is a portable Optical Time Domain Reflectometer (OTDR) offering range settings from 500 m up to 400 km and a typical event dead zone of 0.8 m.\n\nFor spectral analysis of active optical components, the 600 nm to 1700 nm wavelength range is covered by a series of benchtop optical spectrum analyzers (OSAs). This includes the Yokogawa AQ6370, Yokogawa AQ6370C, and Yokogawa AQ6370D. These units provide wavelength resolution settings down to 0.02 nm and high dynamic range, such as up to 73 dB on high-performance editions of the AQ6370C and AQ6370D.

For electronic circuit design and troubleshooting, the Yokogawa DLM2054 mixed-signal oscilloscope integrates 4 analog channels (or 3 analog channels plus 8-bit logic input) with a 500 MHz analog bandwidth. It features up to 2.5 GS/s real-time sampling and an 8.4-inch TFT color display, providing a flexible interface for debugging digital and analog signals simultaneously.
