The Yokogawa NFSB100-S00 is a Signal Conditioner from the NFS series of DIN-rail mounted instruments. It is specifically designed as a Dual-Channel Isolator and Converter.
Its primary function is to accept two independent 4 to 20 mA DC analog input signals from field transmitters (e.g., pressure, temperature, flow), provide electrical isolation between the input, output, and power supply circuits, and convert each input into a corresponding 4 to 20 mA DC output signal.

The Yokogawa CP471-01 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.
Its primary function is to accept a pulse or frequency input signal from a field device (such as a turbine flowmeter, vortex flowmeter, or digital tachometer) and convert it into a standardized 4 to 20 mA DC analog output signal. This allows pulse-generating sensors to be easily integrated into process control systems, PLCs, or DCSs that expect a standard analog input.

The Yokogawa YS1700-021/A03 is a single-loop digital indicating controller from the YS1700 series. It is designed for precise process control in industrial applications such as temperature, pressure, flow, and level regulation.

The Yokogawa AQ2211 is a programmable optical switch module designed for the AQ2200 series Multi-Application Test System. It is not a standalone instrument but a key component used to build automated, flexible test systems for fiber optic components and networks.

The Yokogawa CP471-00 S1 is a Signal Conditioner from the UTAdvanced series of DIN-rail mounted instruments. It is specifically designed as a Pulse (Frequency) to Analog Signal Converter.

The Yokogawa DL850E is a portable, high-performance ScopeCorder. This innovative instrument combines the functionality of a multi-channel digital oscilloscope with the long-term recording capabilities of a high-speed data acquisition recorder.

The Yokogawa PX8000 is a high-end, portable optical spectrum analyzer (OSA). It is designed to bridge the gap between the performance of benchtop OSAs and the convenience of field portability. This instrument is engineered for field installation, maintenance, and commissioning of modern dense wavelength-division multiplexing (DWDM) networks, as well as for use in lab environments where mobility is required.

The Yokogawa AQ2200-342 is not a standalone instrument but a module designed for the AQ2200 series Multi-Application Test System. This system is a modular platform for building customized test solutions for fiber optic components and systems.

The Yokogawa AQ6376 is a bench-top Optical Spectrum Analyzer (OSA) and represents a significant advancement in Yokogawa's OSA series. It is specifically engineered as a premium solution for C-Band and L-Band applications, offering the highest level of performance in its class for dynamic range, resolution, and sensitivity.

The Yokogawa AQ6375 is a bench-top Optical Spectrum Analyzer (OSA) and is part of Yokogawa's high-performance AQ6370 series. It is a specialized instrument optimized for the long-wavelength L-Band and ultra-long-haul applications in optical communication.
