Yokogawa launches ScopeCorder DL850V Vehicle edition: a new third-generation model in the best-selling combined oscilloscope/data recorder family with dedicated automotive testing features

- Enhanced capabilities include CAN Bus monitoring -
The Yokogawa DL850V Vehicle Edition is a new version of Yokogawa's successful ScopeCorder waveform acquisition and recording instrument specifically designed to meet the requirements of the automotive industry.
The Yokogawa ScopeCorder family are versatile instruments that combine the benefits of a high-speed oscilloscope with those of a traditional data acquisition recorder in a single, portable instrument. The new DL850V adds CAN bus monitoring function to the existing ScopeCorder, making it ideally suited to troubleshooting and debugging the CAN (Controller Area Network) in-vehicle serial bus.

Using the DL850V, an engineer can decode the CAN signal and retrieve information on physical data like engine temperature, wheel speed and braking from the CAN bus signal and compare this with the data coming from real sensors. The result is a great deal of time saved compared to other approaches such as analysis on a PC or using other software.
"Yokogawa has become a leader in oscilloscope-based serial bus analysis systems, with products now available covering CAN, LIN, I2C and FlexRay", comments Terry Marrinan, Sales & Marketing Director for Europe & Africa with Yokogawa's Test & Measurement Business Unit: "Now, with the DL850V, we bring the benefits of our combine oscilloscope/recorder technology to this key market sector."
Compared to earlier ScopeCorder units, the DL850V features higher-speed acquisition over a larger number of channels, the ability to carry out real-time recording, a powerful user interface, and a comprehensive range of PC interfacing capabilities for wider functionality and ease of use. With acquisition speeds up to 100 megasamples per second (MS/s), it achieves ten times the sample rate, display, and memory handling speeds as its predecessor.
The DL850V ScopeCorder can accommodate up to 128 channels of assorted types including isolated, simultaneously sampled modules. For users who do not require the highest sample rates, a new 16-channel multiplexed module or a choice of three universal voltage input modules allow speed to be traded off against higher 16-bit voltage resolution, better accuracy and wider input ranges.

With its modular architecture, the DL850V ScopeCorder will handle nearly every type of electrical or physical signal. Users can arbitrarily combine eight different modules out of a range of 15 unique module types, supporting direct input of popular sensors like thermocouples, accelerometers, strain gauges, tachometers., and more. For electrical measurements, an RMS coupled mode makes it possible to monitor and trigger off changes in RMS levels.
The DL850V incorporates a large (10.4-inch) LCD display, an internal hard disk drive, and a thermal printer. Three USB ports, an Ethernet port, an e-SATA port, a video port, a GPIB port, and a SD-card slot populate the unit's left side panel. On the right side, the DL850V has room for eight input modules.
As a diagnostic tool, the DL850V ScopeCorder offers all the measurement and analysis tools of a modern digital oscilloscope, including cursors, waveform parameter calculations, mathematics and DSP channels, fast Fourier transforms and more. In most cases, users will be able to analyse data immediately and get results with no need for offline post-processing.
Yokogawa perfected deep memory, and the ScopeCorder has its share of it: up to two billion points of data can be recorded continuously at 100 MS/s on each channel. Regardless of memory size, the ScopeCorder's GIGAZoom2 engine allows the user to smoothly zoom in and out of a signal, even while acquisition is in progress.
The unique architecture of the DL850V ScopeCorder automatically allocates its memory to best accommodate the user's test strategy. Once the desired sample rate is set, Yokogawa's exclusive ‘history' feature intelligently utilises the remainder of the available memory - allowing the user to view and save previously captured acquisitions.

Another unique function is the ‘dual capture' feature, which allows both high-speed and low-speed rates to be configured. In this mode, the DL850V continuously logs data at the slow speed until a trigger condition is met. At the higher sample rate, the ScopeCorder acquires a transient waveform, with multiple waveforms for multiple triggers, all while continuously logging at the low speed rate.
Electro-mechanical systems demand a different set of measurement techniques than pure electrical systems, and the DL850V delivers higher vertical resolution, channel count, isolation, filtering, and abundant acquisition memory compared to general-purpose oscilloscopes. This makes it ideal for viewing small changes, even across large dynamic ranges, and monitor more signals simultaneously. It also means that there is no need for external signal conditioning components, and that high sample rates can be maintained for longer observation periods.

The DL850V ScopeCorder uses familiar oscilloscope controls, triggers, and analysis functions, so that the higher performance is achieved without additional complexity.
Yokogawa's designers originally conceived the ScopeCorder as an oscilloscope that also has the powerful advantages of a recorder including unattended operation, enabled in the DL850V by functions such as ‘action on trigger' or ‘action on stop'. The DL850V ScopeCorder can also automatically send an e-mail, print captured data, sound an alarm, and save data to a file when it detects a fault condition. Whether observation times are microseconds or months, the ScopeCorder will remain operational and save data until the user is ready for it.
