ScopeCorders combine the real-time transient diagnostic power of a high-bandwidth mixed-signal oscilloscope with the long-term continuous recording capability of a data acquisition system into a single rugged, portable chassis.
Flexible & Swappable Input Modules with Built-in Signal Conditioning
Choose from 20+ types of input modules and install up to 2 in the DL350 Portable ScopeCorder at a time to capture up to 32 channels plus 16 built-in channels of digital input. Input types include:
Up to 20 Gpoints of data per module can be recorded directly to an SD card for continuous recording for up to 50 days. For high speed signals, up to 100 Mpoints per module of internal memory is available to capture fast transients — up to 10,000 times more memory than other portable oscilloscopes or test tools, enabling higher sample rates or longer acquisition periods.
Evaluate power in single-phase and 3-phase systems. For fundamental waveforms of 50 Hz or 60 Hz, up to 40 harmonic orders can be analyzed. Alternatively, use the integrated suite of FFT functions to perform comprehensive full frequency analysis.
Choose simple level triggers or enhanced triggers including pulse width, waveform period, and multi-channel logic. The wave window trigger is ideal for AC power line monitoring to easily capture voltage sags, surges, spikes, phase shifts, or dropouts (40 to 1,000 Hz waveforms).
Leave a DL350 unattended to automatically save the waveform to a file or send a notification email if and when it triggers.
The DL350 combines a 8.4-inch resistive touch screen, physical keys, rechargeable battery operation, and modular signal conditioning into a compact, ruggedized unit ideal for on-the-go automotive driving tests, rail maintenance, and industrial field troubleshooting.
The voltage fluctuations of the input and output of the inverter can be measured alongside the trends of speed, acceleration and braking from the data on the CAN/CAN FD bus.
The optional rechargeable battery pack enables the DL350 to be continuously operated without burdening the in-vehicle power supply.
Up to 20-hours of continuous data can be directly recorded to the SD card with sample rates up to 100 kS/s.
The optional GPS unit* adds coordinate information to the recording data to enable the measurements to be correlated with the location of the vehicle in a drive test.
Dynamic Vehicle Drive
Testing
Use the DL350 with /VE option and bus monitor module to decode CAN/CAN FD, LIN bus or SENT signals and display information such as engine temperature, vehicle speed and brake pedal position as trend waveforms and compare this with the analog data coming from the actual sensors. This enables automotive engineers to gain an insight into the dynamic behavior of the complete electromechanical system.
Isolated Oscilloscope + Data Acquisition System
The DL950 ScopeCorder is a unique combination of a mixed signal oscilloscope and portable data acquisition recorder that can be used to capture both high-speed transient events and long run trends. Only a ScopeCorder has the right combination of channel count, input types, triggering, and recording to tackle the job of electromechanical systems development and troubleshooting. With its multiple measurement types, excellent performance, and high reliability, the DL950 ScopeCorder will quickly become the most valued instrument in your lab.
The DL950 ScopeCorder can be configured as a high-speed data acquisition system or as a long-memory oscilloscope, giving engineers flexibility to capture fast transient events, long-duration trends, and synchronized multi-channel measurements with a single portable instrument.
True Portable Self-Contained Instrument: Combines high-speed waveform capture, long-duration recording, isolated inputs, and application-specific analysis. Supports power, voltage, current, strain, temperature, CAN/CAN FD, LIN, SENT, acceleration, frequency, logic, and other module types to build a measurement system around physical phenomena.
Accurately captures switching waveforms of inverters and fast-moving noise around the power supply.
Using 10 Gbps Ethernet, up to 20 MS/s of data can be stored in real time on a PC. An SFP+ module, a fiber optic cord, and the PC software IS8000 are used for seamless data transfer.
Extend channel counts up to 160 channels by connecting up to four sub-units to a single main unit with optical fiber cords. Measure start/stop, trigger, and sample clock of all sub-units are perfectly synchronized from the main unit. Ideal for multi-point strain tests, multi-point vibration analysis, and battery cell evaluation.
Easy Access to Frequently-Used Applications: Touch any application icon and the graphical setup screen appears. Intuitively change settings prior to measurement by following the wizard screen.
Calculates Park and Clarke transformations in real time from battery DC voltage/current, three-phase motor voltage/current, and motor rotation information. Can be combined with motor parameters, power measurement, and harmonic analysis.
Evaluates EV systems by calculating conversion efficiency from inverter input/output power and analyzing harmonic effects caused by external disturbances while capturing mechanical variations in motor speed and torque.
Calculates rotation angle from pulses output from an encoder and displays the rotation angle trend as a waveform. Rotation angle and control signals can be simultaneously inspected for abnormalities.
For durability testing, resolves conflicting sample rate requirements by simultaneously recording at two different sample rates — capturing transient phenomena with a high-speed sample rate while monitoring low-speed data for long-term trends.
Measures load, pressure, and acceleration by connecting strain gauge transducers such as load cells or torque sensors. Automatically calculates conversions from cumbersome calibration values for easy setup.
Special triggers detect frequency fluctuations, voltage drops, momentary power loss, sags, and surges that are difficult to detect with ordinary triggers.
Performs real-time calculations on captured signals. Triggers, automatic waveform parameter measurements, and cursor measurements on 32 input channels plus 16 real-time math channels are displayed simultaneously.
Stores up to 5,000 history waveforms in acquisition memory. Allows searching by specified conditions (amplitude, frequency, or zone mask) to easily recall and display abnormal transient waveforms after occurrence.
Executes pre-specified actions upon trigger (saving data, sounding buzzer, sending email). Perform pass/fail (GO/NO-GO) determinations based on waveform parameters or shapes.
Designed to be resistant to noise and measure waveforms correctly even when installed close to an inverter. If the touch panel malfunctions, simply turn off the touch panel and operate with keys and jog dial.
Other Functions: Recorder mode (set record time and sample interval), up to eight power supplies for current probes (/P8 option), and operation with USB mouse, keyboard, and external printer.
