"I owe my career to T&M"
It’s not an exaggeration to say I owe a good bit of my career success to Yokogawa Test&Measurement. By using their ScopeCorders that combine the best parts of an oscilloscope and DAQ, projects that once took weeks across multiple instruments suddenly only took a few hours with just one instrument. The impact on what I could accomplish really was quite remarkable, and my ability to accurately complete projects in record time made me look incredible. No matter how complex or convoluted the task, the ScopeCorders never fail to easily handle anything I throw at them. They’re amazing instruments and I tell others about them every chance I get.

Application-Driven Menu
Easy access to frequently-used applications
Touch any application icon and the graphical setup screen appears. Intuitively change the settings prior to measurement by following the wizard screen.
Motor and inverter test
Motor dq analysis function (/MT1 option)
The /MT1 option calculates Park and Clarke transformations in the DL950 from battery DC voltage/current, three-phase motor voltage/ current, and motor rotation information.
It can be combined with motor parameters, power measurement, and harmonic analysis.
A single DL950 can also integrate other measurements such as vibration, temperature, and CAN monitoring.
Power and harmonics analysis (/G05 option)
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)
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.
Long term data recording
Dual capture function
Dual capture function For 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.
Physical phenomena analysis
Strain gauge transducer measurement (/G03 or /G05 option)
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 analysis
Power line abnormality detection (Wave Window Trigger)
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.
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 transfered to a PC.
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.
Summary of each recording mode
Real-time mathematical computation (/G03 or /G05 option)
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.
History function
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.
Action on trigger and GO/NO-GO judgement
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.
High noise resistance
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.
Other functions
- Recorder mode (set the record time and sample interval)
- Up to eight power supplies for current probes (/P8 option)
- Operation with a USB mouse, keyboard, and external printer
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 CAN/ CAN FD Monitor Module (720242), CAN & LIN Bus Monitor Module (720241), and SENT Monitor Module (720243), 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* 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. *Location information acquisition will be available soon.
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).
Intuitive control panel and connectivity
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 500 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 10 MS/s per channel.

Overview:
When I started with my company almost 20 years ago, Yokogawa Test&Measurement instruments were already in use and the engineers had no intention of switching. In fact, we still routinely use some of the older instruments because, well, they just work! The equipment doesn't really become obsolete, and they support their instruments as long as is feasible, which ultimately saves us money. Even so, as things change in our industry Yokogawa adjusts to meet those changes. From our sales representative through technical support and more, I can count on the Yokogawa team to really listen and work with us to provide a specific solution for unique problems.

Overview:
We developed an algorithm to optimize induction motor operation and produce an average power consumption savings of at least 10%. To demonstrate our algorithm’s effectiveness, we needed a proven and verified system that would give these results credibility. The solution provided by Yokogawa Test&Measurement enabled us to monitor and refine our algorithm using real-time speed, power, and temperature readings – data that would normally be incredibly difficult to accurately obtain. Having these real-world results that demonstrate the effectiveness of our algorithm means we can be more efficient with our own customers. —Neil Singer, President, AC Kinetics
