The most feature-rich ScopeCorder, the DL850E combines a mixed signal oscilloscope and portable data acquisition recorder into a modular platform designed to capture both high-speed transients and low speed trends.
Combining signal conditioning, signal processing, and large recording memory, the DL850E is ready to be configured to meet your application demands. With its menu-driven user interface, advanced features are easily accessible, so you can gain insights and solve problems faster.
As the premier instrument in Yokogawa’s ScopeCorder family, the DL850E offers: 
Most processing options
- 29 waveform parameter measurements
- Optional real-time math
- Optional power math
Highest channel count
- 8 input module slots
- Up to 128 channels
- Up to 100 MS/s sampling rate

Making the Difficult Easy
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.

Eliminate Post Processing
Optional Real-Time Math and Power Math Processing
Available real-time digital signal processors calculate math functions or electrical power parameters. Results are plotted on the screen in real-time and can be measured with cursors, captured with triggers, and saved to disk, making the DL850E a productive tool for motors and drives and other time-based power engineering.
GiGAZoom Engine II
Zoom into two billion samples in just the blink of an eye. A dedicated zoom processor can operate two zoom windows with zero delay.
Cursor Measurement
Available cursors are horizontal, vertical, marker, degree or combined horizontal & vertical.
Automated Parameter Measurement
Measure up to 29 different waveform parameters in different time conditions, including:
- Entire waveform
- Per cycle
- Between cursors
- Cycle statistics
- History statistics
Never Miss a Data Point
Capture data for up to 200 days using up to 2Gpoint memory and optional hard disk recording. The History Memory function saves previous trigger data for later search and analysis.
The dual capture function is ideal for long-term testing. Capture the important transient events at a high sample rate while recording steady-state data at a low sample rate. The DL850E automatically switches to a high sampling rate when the trigger condition is met.
Time Synchronization
Correlate data with important events using the optional GPS and IRIG timing functions. The DL850E internal clock and sample clock can be aligned to synchronize multiple systems in remote locations. Merge data sets using XViewer PC software for easier analysis.
Real-Time Measurement of Electrical Power - /G5 option
Get results faster with real-time signal processing for electrical power parameters. Trend calculations such as active power, power factor, integrated power and harmonics, using a dedicated Digital Signal Processor (DSP) that is able to calculate and display up to 126-types of electrical power related parameters in real-time. This enables the user to display raw waveform signals such as voltages and currents along with power calculated parameters and even the capability to trigger on all of them. Data updating rate up to 100kS/s. Trend waveforms of each order of harmonics, bar-graphs and vector displays can be displayed. Both RMS and Power analysis modes are available. Besides the powerful power calculations, the /G5 option also contains all the functionality of the /G3 real-time math option.
Gapless Real-Time Calculations
Taking advantage of the real-time calculations of power parameters allows engineers to create a high-channel count, time series data set of mixed signals including sensors, automotive serial bus data, and accessory analog and discrete inputs. This is ideal for such scenarios as:
- Long-term monitoring or validation of power system performance over hours or days of testing
- Fast transient evaluation while operating test vectors such as start-up, emergency shutdown, or vehicle simulated drive conditions
- Using enhanced triggers to evaluate power parameters and trap unusual behavior for continuous improvement
DL850EV Vehicle Edition
The ScopeCorder Vehicle Edition is designed for engineers working in the automotive and railway industry, providing a thorough insight into the dynamic behavior of the electromechanical system. This integrated approach results in considerable time saving compared to using multiple separate instruments.
CAN/CAN FD or LIN/SENT bus Monitoring
Use a ScopeCorder to decode the CAN/CAN FD or LIN bus or SENT signals and display information on physical data like engine temperature, vehicle speed and brake-pedal position as analog waveforms and compare this with the data coming from real sensors
Powerful Real-Time Calculations and Analysis Functions
As a standard feature, the ScopeCorder is equipped with a set of basic arithmetic functions such as addition, subtraction, division, multiplication, Fast Fourier transformation and more. In addition to standard math, advanced real-time analysis functions are available.
Real-Time Mathematical Computations and Digital Filtering - /G3 option
Armed with a dedicated digital signal processor the ScopeCorder can perform mathematical calculations such as arithmetic operators with coefficients, integrals differentials, and higher order equations on acquired measurement data. The results of these calculations are displayed during waveform capture in real-time. In addition to mathematical operators, steep digital filters can also be selected to isolate or trigger on the amplitude of certain frequency components.
Measuring the electrical angle corresponding to the mechanical angle is important for understanding motor characteristics. The Electrical Angle operation enables the extraction of the fundamental component of current by Discrete Fourier Transform, then the calculation of the phase difference between it and the rotary angle in real-time. A trend of the phase difference can also be displayed in real-time.
User defined computations - /G2 option
With user defined computations it is possible to create equations using a combination of differentials and integrals, digital filters, and a wealth of other functions. Moreover, it is possible to perform various types of FFT analysis using two FFT windows. In applications such as vibration and shock tests, you can easily evaluate abnormal vibrations while simultaneously measuring other signals.

Overview:
There are several factors for a user to consider when using an IEPE accelerometer, particularly when used with newly available integrated signal conditioner/data acquisition process.

- PP Compression as post-process within Xviewer
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

Overview:
You know the basics of electrical power measurements, have set up your dyno, and made key measurements – which is great. But as your motor and drive projects progress, the complexities of system drive requirements can change frequently. Control algorithms, networked communications, and mechanical systems form a complex web of interactions that need sorting. This 60-minute webinar explains how to get past ground-level measurements and delve into comprehensive solutions that leverage test and measurement instruments including power analyzers, high-speed data acquisition, and real-time software.
Topics include:
The technical presentation includes an audience Q&A.
