Featuring a compact vertical design, this instrument is equipped with a large-capacity memory of up to 500 Mpoints, a history function for missed-event playback, and a wide range of features including advanced serial bus analysis and dedicated triggers with its unique “Serial Bus Auto Setup.”
These capabilities strongly support improved measurement efficiency for engineers in the automotive industry.

This is the latest model of an 8-channel input oscilloscope. A single unit supports up to 8 analog channels plus 32-bit logic inputs, improving the efficiency of complex system measurements.
It features the “DLMSync” function, which allows two units to be precisely synchronized to expand the number of channels as needed. In addition, IEEE1588 synchronization enables time-aligned measurements with the DL950 ScopeCorder and WT5000 Precision Power Analyzer.
Enhanced analysis capabilities are provided for automotive bus signals such as CAN, CAN FD, SENT, CXPI, and PSI5 Airbag. The instrument also offers intuitive operability through a combination of a 12.1-inch touchscreen and physical keys/knobs, along with high-speed data transfer to a PC via USB 3.0, delivering numerous features to improve productivity.

The WT1800R supports a wide range of power measurement applications, including efficiency evaluation of automotive motors.
In addition to the class-leading high measurement performance of the conventional WT1800E and its wide input range (10 mA to 50 A without external sensors), the WT1800R also supports Ld and Lq calculations used in high-efficiency motor control. It further enables synchronized measurement with waveform instruments through the integrated measurement software platforms IS8001/IS8002.
By using the optional accessory (Model: 761961), the WT1800R main unit (/PD2 option) can supply power to the AC/DC split-core current sensor CT1000S. This allows for easy installation and removal without cutting the cable when measuring currents exceeding 50 A. In addition, since no external probe power supply is required, wiring is simplified. Integrating the measurement instrument and power supply also helps reduce noise, ensuring reliable measurement even in harsh noise environments.

This is a 4U-height, rack-mountable insulated oscilloscope/high-speed DAQ designed for system integration. It supports long-duration, multi-channel recording of voltage, current, temperature, acceleration, strain, pulse, digital, and communication signals such as CAN, CAN FD, LIN, and SENT.
Without interrupting measurement, it enables real-time waveform processing, power calculations, and motor dq analysis. When combined with the IS8000 integrated measurement software platform, instrument and recording settings required for standardized and endurance testing can be configured easily without complex operations.

For the design and evaluation of high-efficiency motor and inverter systems, accurate measurement of power conversion efficiency, acquisition of high-speed switching waveforms, and detailed analysis of their relationship with torque are essential.
By combining the high-precision WT5000 power analyzer, DL950 ScopeCorder, and IS8000 software, highly reliable power data, high-speed voltage and current waveforms, and motor torque waveforms can be precisely synchronized, enabling unified visualization and analysis as integrated measurement data.

The WT5000 is a 7-channel high-precision power analyzer that achieves world-class measurement accuracy. Its current sensor elements incorporate built-in sensor power supplies, allowing easy connection to AC/DC current sensors (CT series) with a single dedicated cable.
In addition, with its high-speed waveform streaming function, waveform data input to the WT5000 can be continuously output to a PC at up to 2 MS/s, or up to 22 channels (7 voltage channels, 7 current channels, and 4 torque/speed channels).
By synchronizing waveform data with power measurement parameters, more detailed and advanced power analysis can be achieved.

This is the latest model of an insulated oscilloscope that combines the functionality of an oscilloscope and a multi-channel data recorder. It simultaneously captures and records signals such as low- to high-voltage (up to 1000 V), drive current, rotational angle, vibration, strain, and temperature.
Equipped with a 200 MS/s, 14-bit module and a 4-channel, 10 MS/s, 16-bit module, it is ideal for multi-channel measurements and capturing transient phenomena in motor and inverter systems that were previously difficult to observe.
A touchscreen interface, combined with physical keys, enables intuitive operation and improves workflow efficiency. For multi-unit synchronization, up to five units can be synchronized, or up to eight units using IEEE1588.

In motor development, where high-current and high-frequency measurement is required, the selection of a current sensor is a critical factor directly affecting measurement accuracy.
The CT1000S is a split-core type sensor that allows easy installation and removal without disconnecting the circuit, while enabling wide-bandwidth measurement of large currents up to 1000 A and 300 kHz.
While conventional current sensors are typically designed either for waveform measurement instruments or for power analyzers, the CT1000S can be used with both. This eliminates the need for multiple types of sensors and helps reduce both installation effort and overall costs.
