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.

Improving Accelerometer Measurement Reliability in Data Acquisition Systems
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.
Finding Absolute Position of Electric Motors with Yokogawa ScopeCorders
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 process. Correctly managing these factors will help the user avoid erroneous data from their IEPE accelerometer and ensure the quality of the data measurement 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:
- Improved speed vs torque characteristics
- High dynamic response
- High efficiency
- Extended speed ranges
- Long operation life
- Construction and verification of SENT communication system
- Accurate, reliable data transmission at low cost
Use built-in calculations to analyze motor rotor position of Brushless DC motors (BLDC) and Permanent Magnet Synchronous Machines (PMSM) and find the relative angle between the rotor and position sensors such as encoders or resolvers
