-
The DL950 is a unique combination of a mixed signal oscilloscope and portable data acquisition recorder that can be used to capture both high speed transient events and long run trends
Only a ScopeCorder has the right combination of channel count, input types, triggering, and recording to tackle the job of electromechanical systems development and troubleshooting. With its multiple measurement types, excellent performance, and high reliability, the DL950 ScopeCorder will quickly become the most valued instrument in your lab.
Accurately captures switching waveforms of inverters and fastmoving noises around the power supply.
Using 10 Gbps Ethernet, up to 20 MS/s of data can be stored in real time on a PC. An SFP+ module, a fiber optic cord, and the PC software IS8000 are used for data transfer. *Please use a commercially available SFP+ module and a 10 GE fiber optic cord.When transferring files, high speed transfer is not possible.
The number of channels can be extended up to 160 by connecting up to four sub units to a single main unit with optical fiber cords. Synchronize measure start/stop, trigger, and sample clock of the sub units from the main unit.
Time synchronization with IEEE1588 signals is available. With the /C40 option, the DL950 can output IEEE1588 master signals. Time synchronization using IRIG and GPS is also available (/C35 option).
Applications *Please use the Optical Transceiver Module 720941 and the Fiber Optic Cord 720942
Touch any application icon and the graphical setup screen appears. Intuitively change the settings prior to measurement by following the wizard screen.
Power and harmonics analysis (/G05 option)A single DL950 is all you need to evaluate a system with battery-driven motors, such as an EV. The DL950 calculates the conversion efficiency from the input and output power of the inverter and analyzes the effects of harmonics caused by external disturbances while capturing mechanical variations in motor speed and torque.
Encoder rotary angle (/G03 or /G05 option)The DL950 can calculate the rotation angle from the pulses output from an encoder and display the trend of the rotation angle as a waveform. The rotation angle and its control signal can be simultaneously observed and inspected for abnormalities.
Dual capture functionFor durability testing, it is necessary to capture transient phenomena with a high-speed sample rate, even when monitoring low-speed data to visualize long-term trends. The dual capture function uniquely resolves these conflicting requirements by simultaneously recording at two different sample rates.
Strain gauge transducer measurement (/G03 or /G05 option)Load, pressure, and acceleration can be measured by connecting a strain gauge-type transducer such as a load cell or torque sensor. This feature automatically calculates conversions from cumbersome calibration values and enables easy setting.
Power line abnormality detection (Wave Window Trigger)Special triggers are used to detect frequency fluctuations, voltage drops, and other phenomena that are difficult to detect with ordinary triggers. These triggers can also be used to detect typical power supply problems such as momentary power loss, sags, and surges.
-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.
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.
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 transfered 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.
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.
Various calculations are performed on captured signals and the results are displayed on the screen in real time. Perform triggers, automatic waveform parameter measurements, and cursor measurements. Independent input channels, real-time calculation results of 32 input channels plus 16 real time math channels can be displayed and analyzed simultaneously.
Any abnormalities occurring during repeated waveform measurement will have disappeared by the time they are noticed. Since the DL950 stores up to 5000 waveforms (history waveforms) in the acquisition memory, it is possible to go back and display the abnormal waveforms. Search for and easily find waveforms from the stored history waveforms and display only those that match specified conditions. Search conditions such as amplitude, frequency, or a zone that a waveform passes through or does not pass through can be specified.
This performs multiple actions specified in advance when a trigger occurs, such as saving data file, buzzer and email transmission. Also, pass or fail (GO/NO-GO) determination can be performed based on waveform parameters, such as waveform shape or amplitude, and an action can be executed according to the determination results.
The DL950 is designed to be resistant to noise and can measure waveforms correctly even when installed close to an inverter. If the touch panel malfunctions, simply turn off the touch panel and use the keys and jog dial to operate it.
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.
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.
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.
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.
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.
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.
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.
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).

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.
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.
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.
