DL950 Isolated Oscilloscope + Data Acquisition Recording Options
8 G points large memory (/M2 option)
With up to 8 G points of memory and 20 seconds of continuous capturing, even at 200 MS/s, no signal changes are missed. *Up to 4 G points of memory is allocated per channel.
SSD recording (/ST1 or /ST2 option)
The 512 GB internal SSD can record for long periods of time at up to 2 MS/s. Waveforms from dual capture can also be recorded, which is useful for in-vehicle endurance testing and capturing rare spontaneous events.
Flash acquisition (/ST2 option)
Long time recording at up to 20 MS/s, which is 100 times faster than the previous model, is available. You can capture data anywhere you cannot bring a PC such as on-vehicle or field testing. The flash memory is non-volatile, so the captured data stays in the instrument even after turning off the power. Data can later be transferred to a PC.
Deletion of the recorded data on the flash memory is not done for each recorded data but for all the data at once.
When transferring recorded data to a PC, please use the IS8000 or re-save the data in WDF format.
Multi-sample rates
Sample rates can be set by channel. Reducing the sample rate reduces the amount of data even when modules with high and low sample rates are mixed together. This allows for less memory space to be used and improves the transfer speed.

Example Applications
2-motor/4-motor system test for EV
In the development of Hybrid Electric Vehicles (HEVs), a 2-motor or 4-motor system in which a motor is directly connected to each driving wheel is applied. This eliminates powertrains, which enhances the design and removes anxiety when driving a 4WD on a snowy road. The multi-channel/high-speed isolated DL950 can capture signals and analyze them at the same time in the multiple motor systems.
High noise immunity
The DL950 measures the DC power on the battery side and the AC power on the 3-phase motor side at the same time. It simultaneously measures all inverters, including the power generation motor, and evaluates the conversion efficiency. With its high noise immunity, the DL950 minimizes the effect of switching noise generated by the inverters. CAN, CAN FD, LIN, and SENT signals from the ECU and the temperature rise in each part can be captured at the same time. Data can be saved in a MATLAB format as well. When an isolated module is used, there is isolation between the body and channels and isolation between channels, so that different points of common potential can be safely measured.
Distributed energy resource test (renewable energy)
The DL950 supports renewable energy sources which contribute to a sustainable society. For wind turbines, the efficiency of power generation at multiple locations needs to be monitored in a time-synchronized manner. This can be done by GPS and IRIG. In addition, the DC/AC conversion efficiency for loading the DC power onto the grid can be accurately measured by the WT5000 high-precision power analyzer via IS8000. The power values and their trends can be analyzed.
Vibration analysis solution
All moving things are bound to have vibration. The DL950’s acceleration module allows for simultaneous capture of multiple vibration frequencies. Use the FFT function to analyze the frequencies and find abnormalities.
In-vehicle data measurement solution
The DL950/VCE option provides enhanced features and functions mainly for vehicle development and evaluation. Supporting 720245 CAN FD/LIN Monitor Module and 720243 SENT Monitor Module, the DL950 can display each protocol communication data of in-vehicle networks as trend waveforms on the monitor. It can also trigger on decoded waveforms.
Comparative verification between measured signals and CAN/CAN FD bus signals
The CAN/CAN FD bus data and related waveforms can be viewed on the same screen. For example, an ignition switch ON/OFF signal, a CAN FD signal corresponding to that command, and pressure signals can be checked on the same screen to verify the correlation between them.
Location and time information inclusion
By connecting an accessory GPS unit, information such as location (latitude, longitude, altitude, and so on) and time can be included in measurement data. Correlation between the location of a vehicle and power data, CAN data, or other types of data can be viewed during a vehicle drive test.
Utilization of vehicle-installed network definition files
The Symbol Editor is a software tool that makes it possible to define which physical values from the CAN/CAN FD or LIN bus data frame have to be trended as waveform data on the display of the ScopeCorder. The Symbol Editor can accept vehicle-installed network definition files (CAN DBC, LIN LDF).
DL950 Isolated Oscilloscope + Data Acquisition Interface
Intuitive control panel and connectivity
DL950 Isolated Oscilloscope + Data Acquisition Software
Integrated measurement with multiple instruments
Integrated measurement software platform IS8000
The IS8000 enables synchronized measurements with DL950s, Yokogawa power meters, other manufacturers’ high-speed cameras, and other equipment. It supports measurement setting, remote monitoring, comparative analysis, and MDF file saving to reduce test system development time.
High-precision synchronized measurement of power values and waveform data
The WT5000 high-precision power analyzer and DL950 support the IEEE1588 standards. This allows measured power values and transient physical quantities to be synchronized with an error of less than 10 μs and displayed on the IS8000. It is effective for efficiency evaluation and ECU design, which are essential for designing more efficient motor inverters.
PC streaming
By combining the DL950 and IS8000, data can be recorded directly into a PC‘s storage in real time. Using 10 Gbps Ethernet enables recording at up to 20 MS/s per channel.
