  • Standard memory 250MPoint
  • Expanded memory 1GPoint (/M1 Option)
  • Expanded memory 2GPoint (/M2 Option)

Giga Zoom Engine II

Zoom into 2 Billion samples in just a blink of the eye. Each ScopeCorder is equipped with the revolutionary Giga Zoom Engine II, a powerful processor designed for optimizing access to data seamlessly. It is possible to activate 2 zoom windows while displaying the entire original signal. 

Capture and record detailed waveforms from milliseconds up to months

A ScopeCorder provides a wide variety of unique acquisition features to handle small or large amounts of data. Therefore it can perform multi-channel measurements for longer measurement periods while still being able to precisely capture transient events with the highest detail.

Reduce time spend on fault finding or transient analysis - simple & enhanced triggers

Having the possibility to set individual triggers on multiple channels provides the power to investigate what causes a particular transient event. Moreover, the availability of a large acquisition memory, and thus longer measurement time, helps the analysis of the effect of such an event on other parts of the application.

Wave Window Trigger
The ideal trigger for AC power line monitoring. Easily capture voltage sags, interfering impulses, phase shifts or drop outs.

Action on trigger
Leave a ScopeCorder unattended and automatically save the waveform to a file or send an email for notification of a trigger event.

Capture High-Speed Transients During Long Term Recording - Dual capture

To visualize long term trends for durability testing, data is typically acquired at lower speed sample rates. On the other hand, suddenly-occurring transitional phenomena have to be captured at high-speed sample rates and detail to be able to investigate the event. The "Dual Capture" function uniquely resolves these conflicting requirements by recording at two different sampling rates.

Set waveform triggers and capture 5,000 high-speed transient events at sample rates up to 100 MS/s, while at the same time continuously record trend measurements at up to 100kS/s.

Recall waveform events - History Memory

When an abnormal phenomenon is spotted during a repetitive high speed measurement, the anomaly has often already disappeared from the screen by the time the measurement is stopped. With a ScopeCorder the "History" function is always active and automatically divides the available acquisition memory in up to 5,000 "history waveforms".

These history records are easily accessible and can be displayed simultaneously after measurement is stopped. Using condition-based searches inside the history memory, users can quickly isolate individual waveforms records. Once the required waveforms have been identified they can be used for further analysis.

Cursor Measurement

Using cursors is a quick and easy method to measure waveform parameters on the screen. Available cursors are horizontal, vertical, marker, degree or combined horizontal & vertical.

Automatic Waveform Parameter Measurement

The parameter measure function is the most precise method for automatically calculating any or all of the 28 different waveform parameters such as, amplitude, peak to peak values, RMS, rise time, frequency and more.The internal time clock (date and time) can be synchronized and adjusted across multiple units. Applications are likely to include synchronizing the ScopeCorder at a windmill farm, finding faults in power grids, and more.

Cycle Statistics

With this powerful analysis function, the ScopeCorder measures selected parameters individually for each waveform cycle and provides statistical information which can easily be saved to a file. By selecting maximum or minimum values from the results, the instrument can automatically zoom into the selected waveform cycle for further analysis, potentially saving additional data analysis time.

Real-time hard disk recording

Use a ScopeCorder as a measurement platform for simple durability testing up to 200 days. Realtime hard disk recording enables measurement data to be streamed directly to either a built-in hard drive (/HD0 option) or via the eSATA interface (/HD1 option) to an external hard drive.DL850E Real Time HDD Recording Copy

Armed with a dedicated digital signal processor the ScopeCoder 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. 

DL850E Real Time Mathematical

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.

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.

CAN and LIN Bus Monitoring

Use a ScopeCoder to decode the CAN 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 


DL850E CAN Lin Bu 2

Symbol Editor

The symbol editor is a software tool which makes it possible to define which physical values from the CAN- 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).

Battery Powered Operation - /DC option

In addition to AC power, it is also possible to take the ScopeCorder Vehicle Edition in a vehicle and power the unit from the vehicle's DC battery. The DC power option allows AC and DC power supplies to be used together to ensure a highly reliable power source. If the AC power goes down, the DL850EV instantly switches to the DC supply without interrupting the measurement.

  • DC power (10 - 18V)
  • AC power (100 - 120V / 200 - 240V)

Applications in Power & Transportation

With today's increased incorporation of power electronics and switching devices in power and transportation related applications, measuring the power consumption and performance of the individual components alone is often not sufficient to understand the overall performance and behavior of a system.

A ScopeCorder satisfies this new measurement requirement by not only capturing voltage and current waveforms but combines these with real-time calculations of power and other electrical and physical parameters in a single measurement overview.

Motors and Electric Drives

The majority of industrial applications incorporate a variable speed drive in combination with a threephase induction motor. Where an Oscilloscope often has a limited channel count and non-isolated input channels, the DL850E can be equipped with 16 or more channels and has a diverse range of input modules, where each channel is individually isolated.

The instrument offers direct input of voltages up to 1000V, with no need for active probing, and samples data at rates up to 100MS/s with 12 or 16 Bit vertical resolution. These features are ideal for capturing inverter switching signals with high precision.

Being able to connect the outputs from additional torque sensors, rotary encoders or thermocouples also makes the DL850E ScopeCorder an ideal measuring instrument to enable engineers to improve the design of motor and electric drives, reduce size and costs, and increase efficiency levels. This in turn helps to reduce global industrial power consumption.

Analyze the Dynamics of Electric Drive Trains

Combine electrical signals and physical sensor parameters, related to mechanical performance, with data from the control system such as a CAN or LIN bus. This enables R&D engineers to identify the correlation between communication data transmitted over the vehicle bus and analog data such as voltage, temperature and sensor signals, or the ECU's control logic signals.
