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
Highest channel count
Choose from 20 types of input modules and install up to 8 in the DL850E ScopeCorder at a time to capture up to 128 channels. Input types include:
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.
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:
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.
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.
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.
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:
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.
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
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.
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.
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.

The ScopeCorder DL850E was designed with built-in antialiasing filters to accept inputs from wide bandwidth, high voltage accelerometers, providing low impedance inputs for excellent noise eliminating characteristics.
Properly orienting the north pole of the rotor is critical to the goals of Field Oriented Control and allows the results of the Park and Clarke transformations to be more accurate. The DL850 with Real-Time Math eliminates programming and post-processing, serving as an essential tool for the motor drive designer or drive system integrator.
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 systems. Correctly managing these factors will help the user avoid erroneous data from their IEPE accelerometer and ensure the quality of the measurement data is at the level they expect and require.
With the increased demand in electric-hybrid vehicles, the electromechanical designs of in-vehicle systems are becoming more sophisticated and there has been a demand shift towards high efficiency brushless direct current motor (BLDC) implementation. Think of motorized seat adjustment, electric window, power steering, HVAC fans, pumps, etc. In many of these systems various types of motors are used as actuators; more specifically, 3-phase BLDC motors are gaining popularity as they provide these important advantages:
