The Yokogawa DL850E ScopeCorder is a highly versatile, modular data acquisition instrument that perfectly bridges the gap between a high-speed oscilloscope and a traditional data logger. Engineered for the electromechanical, power electronics, and automotive industries, it excels at capturing high-speed transient events while simultaneously performing long-term recording. When you are analyzing complex systems like inverters, motor drives, or vehicular power trains, you need an instrument that can view control signals, high voltages, temperatures, and mechanical parameters all on a single time axis. The Yokogawa DL850E is built precisely for this comprehensive, multi-domain analysis.

Its modular architecture features eight individual plug-in slots, allowing you to customize the channel configuration to meet your exact testing requirements. With over 20 different available modules, the Yokogawa DL850E can directly measure voltage, current, temperature, strain, acceleration, and frequency. One of its most significant advantages is its robust input isolation. Unlike standard oscilloscopes that require expensive active differential probes for safe high-voltage measurements, the Yokogawa DL850E offers modules with up to 1000 V direct isolated inputs. This ensures operator safety and superior noise rejection without the clutter and extra cost of external probing accessories.

Equipped with a maximum sampling rate of 100 MS/s and an immense memory capacity of up to 2 Giga-points, the Yokogawa DL850E captures every minute detail of a transient fault while recording hours of baseline data. Furthermore, its dual-capture feature allows it to record slow trends at a low sample rate and automatically trigger a high-speed capture of fast transients simultaneously.

Key Features & Capabilities

• Fully Modular Architecture: Customize your data acquisition with 8 individual plug-in slots supporting over 20 different module types. Easily mix and match modules to measure voltage, current, temperature, strain, vibration, acceleration, and CAN/LIN bus signals simultaneously.

• Direct High-Voltage Measurement: Enhance operator safety and signal integrity with isolated input modules capable of handling up to 1000 V RMS directly, entirely eliminating the need for bulky, expensive, and noise-prone external differential probes.

• High-Speed & High-Resolution Capture: Catch the fastest transient events and anomalies with sampling rates up to 100 MS/s and exceptionally clear 12-bit to 16-bit analog-to-digital (A/D) resolution.

• Massive Memory & Storage: Equipped with up to 2 Gpoints of internal memory for deep, high-speed data capture. For extended testing, it supports real-time continuous data streaming directly to an internal hard drive or external eSATA drive at up to 100 kS/s.

• Dual Capture Functionality: Perfect for durability and lifecycle testing. The instrument can record long-term, slow-changing trends at low sample rates while simultaneously triggering to capture high-speed transient faults in a separate memory block without missing a single data point.

• Real-Time Math & Power Analysis (Optional): Perform complex calculations on the fly, including real-time mathematical filtering, integration, and dedicated power calculations (active power, reactive power, power factor, and harmonic analysis) directly on the instrument.

• Intuitive Interface & Display: Features a bright, high-resolution 10.4-inch color TFT LCD monitor that allows users to easily visualize multiple waveforms, digital logic, and calculated trends on a single time axis.

Frequently Asked Questions (FAQ)

1. What is the difference between the DL850E and the DL850EV?

The DL850EV is the “Vehicle Edition” of the ScopeCorder. While it shares the same hardware platform as the DL850E, the EV version includes specialized features for automotive testing, such as the ability to monitor and decode CAN and LIN bus data directly alongside physical analog signals like voltage and temperature.

2. Do I need differential probes to measure high voltages?

No. One of the biggest advantages of the DL850E is that you can equip it with isolated input modules. These modules safely isolate the input channels from the instrument ground and from each other, allowing you to measure up to 1000 V directly without external active probes.

3. Can I record data directly to an external hard drive?

Yes. The DL850E features a real-time hard disk recording function. You can stream digitized data directly to the internal hard drive or to an external eSATA drive for extremely long continuous recording sessions that exceed the internal RAM limits.

4. Can it capture high-speed transients during a long-term recording?

Yes, utilizing the “Dual Capture” function. The instrument can record data continuously at a low sampling rate for trend analysis, while simultaneously acting on a trigger to capture high-speed transient events at up to 100 MS/s in a separate memory block.

5. Are modules hot-swappable?

No. The instrument must be powered down before inserting or removing the measurement modules to prevent damage to the internal bus and the modules themselves.
