Yokogawa Test & Measurement Corporation

This is the latest model of the 8-channel input oscilloscope. One unit supports up to 8 analog channels + 32bit logic. Improves the efficiency of measuring complex systems. The "DLMsync" function is now supported to synchronize the two devices with high precision and expand the number of channels as needed. In addition, the IEEE1588 synchronization function enables time synchronization with the Scope Coder DL950 and Precision Power Analyzer WT5000. The on-board bus signal analysis functions such as CAN/CAN FD/SENT/CXPI/PSI5 Airbag are further enhanced. It is packed full of functions for improving productivity, such as intuitive operation through a combination of 12.1 inch touch panel, keys and knobs, and USB3.0 for high-speed DATA communication with PC.

With a vertical compact body, it features a large-capacity memory of up to 500M points, a missed playback function through the history function, and various powerful features such as strong serial bus analysis and dedicated triggers, including the unique "Serial Bus Auto Setup." It strongly supports the measurement work efficiency of engineers in the automotive industry.

The WT1800R supports a wide range of power measurement applications, including automotive motor efficiency evaluation.
In addition to the class-leading measurement performance of the conventional WT1800E and the wide input range that can measure 10 mA to 50 A without an external sensor, it also supports the calculation of Ld and Lq used to control high-efficiency motors and synchronous measurement with waveform measuring instruments using the integrated measurement software platform IS8001/IS8002.
The optional accessory (model name: 761961) can be used to supply Power supply from the WT1800R (/PD2 Option) to the AC/DC split-core current sensor CT1000S. When measuring a large current exceeding 50 A, the cable to be measured can be easily installed and removed without cutting it. Furthermore, since the external probe Power supply is not required, the wiring is not only clean, but also noise control is achieved by integrating the measuring instrument and Power supply, enabling reliable measurement even in severe noise environments.

An insulated oscilloscope/high-speed DAQ that can be fixed to a system rack and has a height of 4U. Multi-channel long time recording of voltage/current, temperature, acceleration, strain, pulse, digital, CAN/CAN FD/LIN/SENT communication signals is possible. Waveform calculation, power calculation and motor dq analysis can be performed in real time without stopping the measurement. Combined with the integrated measurement software platform IS8000, the instrument settings and recording settings required for routine tests and endurance tests can be easily set without complicated operations.

Accurate measurement of power conversion efficiency, acquisition of fast switching waveforms, and detailed analysis of the relationship with torque are essential to design evaluation of highly efficient motor inverter systems.
By combining the high-precision power meter WT5000, Scope Coder DL950, and Software IS8000, highly reliable power measurements, high-speed voltage and current waveforms, and motor torque waveforms are synchronized with high precision, and display and analysis as an integrated measurement DATA is realized.

The WT5000 is a 7 channel input high-precision power meter that achieves the world's highest power measurement accuracy. The "Current Sensor Element" has a built-in sensor Power supply and can be easily connected to the AC/DC current sensor CT series with a single dedicated cable. The waveform DATA input to the WT5000 can be continuously output to a PC at speeds up to 2 MS/s or up to 22 channels (Voltage/Current 7 channels each, Torque/Rotation speed 4 channels) thanks to the waveform DATA's high-speed streaming function. More detailed power analysis is possible from the waveform synchronized with the power value Parameter.

This is the latest model of an insulated oscilloscope that combines an oscilloscope with a multi-channel data recorder. High voltages from low voltage to 1000 V, driving current, rotation angle, vibration, strain, temperature, etc. are simultaneously captured and recorded in DATA. The use of the 200 MS/s high-speed sampling 14bit module and the 4 channel 10 MS/s 16bit module makes it ideal for multi-channel measurement of motor inverter transients that have not been detected before. Equipped with a touch panel, intuitive operation combined with physical keys helps improve work efficiency. Up to 5 devices can be synchronized using the multi-device synchronization function, and up to 8 devices can be synchronized using the IEEE1588 function.

In the development of motors that require high current and high frequency measurement, the selection of a current sensor is an important factor directly related to measurement accuracy. The CT1000S is a split-core type that can be easily removed from the object to be measured, yet realizes high-current wide-band measurement, and can measure up to 1000 A and 300 kHz. The CT1000S can be used as either a waveform meter or a power meter. It eliminates the need to prepare two types of current sensors, which also contributes to the reduction of man-hours and costs for removing them from the target to be measured.
