The ScopeCorder Vehicle Edition is designed for engineers working in the automotive and railway industry. A common measurement challenge is to combine measurements of electrical signals, physical performance parameters, indicated by sensors, together with CAN- or LIN-bus data transmitted by the powertrain management system. A ScopeCorder Vehicle Edition addresses this requirement by providing a thorough insight into the dynamic behavior of the electromechanical system. The result is a considerable saving of time compared to other approaches such as analysis on a PC or the use of other software.
The DL850EV ScopeCorder Vehicle Edition can display CAN- and/or LIN-protocol communication data as trend waveforms on the display by using the CAN Bus Monitor Module (720240) or CAN & LIN Bus Monitor Module (720241). By identifying the correlation between communication data on the vehicle-installed LAN and analog data such as voltage, temperature, and sensor signals or the ECU’s control logic signal, a vehicle’s overall LAN system can be evaluated.

Never miss the waveforms you want to capture.

  • High speed (100 MS/s), High resolution (12-bit), 1kV isolated measurements. — Yokogawa’s isoPRO technology offers industry leading isolation performance at the highest speeds. The isoPRO core technology is designed with energy savings applications in mind. It gives you the performance needed to develop high efficiency inverters, which employ high voltages, large currents, and high operating speeds.

    Using 720210 High-speed 100 MS/s 12-Bit Isolation Module
  • Using high speed optical fiber-based transmissions, the module achieves high speed ADC clock and data isolation.

Powerful Real-Time Calculations and Analysis Functions

Armed with a dedicated digital signal processor the ScopeCorder can perform mathematical calculations such as arithmetic operators with coefficients, integrals and 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
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 125-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.

Advanced – Measurement Points – Up to 128 CH of voltage input and 128 bits of logic input

  • 16-CH Voltage Input Module (scanner type) can measure at 10 kS/s sample rate even when using all 16 channels. With this module populating all 8 input module slots, the DL850EV performs 128-CH voltage measurements.
  • The Logic Input Module supports everything from TTL levels, to high voltage contact closures at up to 10 MS/s. With eight logic modules, the DL850EV can monitor and capture 128 bits of logic.

Large (up to 2 GPoint with /M2 option) memory offers long duration measurement and two instantaneous zoom locations

— Comes standard with 250 MPoints of memory, expandable with 1or 2 GPoint options. Large capacity memory does not simply provide longer durations of measurement.

  • High speed update The DL850E Series DSO Models not only updates the display at high speed, but also include a function to recal up to 2000 screens worth of past waveforms.
  • High-speed screen updating alone does not allow users to take full advantage of the digital oscilloscope. Rather, the ability to redisplay and analyzing individual waveforms unleash the digital oscilloscope’s full potential.

Long Duration, Continuous Saving of Waveforms -Continuous Data Recording

  • Measured data can be streamed directly to a built-in 160 GB hard disk (/HD1 option) or through the external HDD interface (/HD0 option). With long duration evaluation testing, measurements can be performed at 100 kS/s on 16 channels simultaneously for 10 hours
  • Data being continuously recorded on the DL850E/DL850EV’s built-in HDD or external HDD can be transferred to a PC without stopping measurement. You can display and analyze the transferred waveform data using Xviewer, an accessory program for the PC.

Search & Zoom – History Function

— When you spot an abnormal phenomenon during repetitive high speed measurements, often the anomaly has disappeared from the screen by the time you press Stop. Always active, the "History" function automatically divides the long memory into up to 5,000 "history waveforms" that can be re-displayed at any time.

  • Searching history waveforms When you want to extract specific c abnormal phenomena, you can perform condition-based searches inside the history waveforms. You can create a rectangular zone on screen and extract only waveforms that pass through or do not pass through the zone. You can also extract data based on parameters such as amplitude or RMS.

Dual-window Zoom function simultaneously zooms in on two areas

  • Two individual zoom factors and positions can be set with independent time scales and displayed simultaneously. Also, using the auto scroll function, you can automatically scroll waveforms captured in long memory and change the position of the zoom areas. Choose any display position with forward, backward, fast forward, pause, and other controls. Dual-window zoom function

Catch transients in durability with high-speed sampling – Dual Capture

  • To visualize long term trends in durability testing and other situations, data is typically acquired at low speed sample rates. On the other hand, suddenly-occurring transitional phenomena should be captured at high-speed sample rates.
    The "Dual Capture" feature resolves these conflicting requirements by recording at two different sampling rates.
  • Zoom Waveform – You can record up to 5,000 phenomena of high speed trigger measurements (up to 100 MS/s) at a record length of 5-500 kPoints while taking trend measurements at up to 100 kS/s.
  • Event Waveform -Displays the timing at which high speed "sub" waveforms are acquired
  • Low Speed Main Waveform – Max: 100 kS/s Trend waveform displayed in a low-speed Roll mode
  • Capture Waveform – Max 100 MS/s Capture transients with high speed trigger measurement

Processes Noise Rejection and Executes Power Computations in Real Time – Real time Math

  • The DL850E is armed with a dedicated DSP (digital signal processor) for computations that enables between-channel math during waveform capture. These between-channel computations are powerful because they can be set up separately from filter computations. In addition to FIR, IIR, Gauss, and moving average filters, you can use arithmetic with coefficients, integrals and differentials, and higher-order equations.

GPS Interface (/C30 option)

  • A GPS antenna can be directly connected to the ScopeCorder side panel. The instruments time clock and the sampling clock will be synchronized to the GPS clock.

User Defined Computation (/G2 option)

  • The DL comes standard with arithmetic, time shift, FFT, and other computations that enable you to display waveforms with offsets and skew corrections. And with user defined computations (/G2 option), you can create equations using a combination of differentials and integrals, digital filters, and a wealth of other functions.

Automatically extract waveform amplitude, frequency, and other parameters – Waveform parameter and statistical computation

  • Extract and display up to 24 of the 26 available waveform parameters (amplitude, frequency, etc.) simultaneously. Menus can be shown as lists of easy-to-read icons.

Detect Abnormal Waveforms, Notify Users, and Determine Pass/Fail – Go/NO-GO Determination

  • The DL can determine whether waveforms or computed values of waveform parameters meet (GO) or do not meet (NO-GO) conditions that are specified in advance. Upon judgment of the measured results, a pre-set action is performed and users are notified that an abnormal waveform was observed, along with the pass/fail determination. This is a very useful function for such things as studying signals from manufacturing lines of electronic devices and tracing abnormal phenomena

Synchronize multiple units performing simultaneous measurements

Synchronized measurement across multiple DL850E units is made possible by inputting an IRIG time code signal.* The DL850E/DL850EV’s internal clock is also synchronized (locked) to the IRIG signal. Therefore, timing comparisons are highly precise even when continuously recording over long periods of time.

  • You can make periodic observations remotely by connecting commercially available GPS receivers that have IRIG output and using the Time Trigger function

Check the relationship between hysteresis and phase

XY display function

  • You can confirm the relationship between two signals using the X-Y display. This can be applied to measurements such as the phase angle of two sine waves. You can select four combinations on the X and Y axes, and therefore display multiple X-Y waveforms simultaneously and find relationships between them. Simultaneous observation of X-Y waveforms and normal T-Y waveforms (waveform display using voltage and time axes) is also possible.
  • (1) Ensures security Simply remove the drive after measurement to protect data. Or, keep restricted data only at the measurement site.
  • (2) Increases capacity If the external hard drive becomes full, you can simply switch to a new one (requires a restart).
  • (3) Hi-speed data transfer A data can be transferred at high speed between a PC and a hard drive
  • Computing dynamic BH characteristics of a magnetic substance On the DL850E you can measure voltage and current, then analyze hysteresis of magnetic flux density B and magnetic field strength H. Energy loss generated by magnetostriction can be evaluated by measuring dynamic BH characteristics


  • With the push of "SNAP SHOT" key, you can save a "snapshot" of the measured waveform (the waveform displayed on screen). The waveform remains saved even if you restart measurement, therefore you can easily compare the snapshot with any newly measured waveforms. Snapshots can also be saved and loaded as files.

Web server

  • The Web Server function displays the screen of any networked DL850E/DL850EV on a PC via Ethernet. From this screen, you can remotely start or stop measurement, update the DL’s display, and take snapshots (capture images) of the screens.

Saving screen images and displaying thumbnails

  • Screen images can be saved to a specified storage medium in PNG, JPEG, or BMP format. These screen images can be imported into reports or other PC-created documents.
