The new units are the 720211 high-speed (100 MS/s) 12-bit isolation module, the 720243 SENT monitor module (available only for the DL850EV ScopeCorder Vehicle Edition), and the 720254 4-channel 1 MS/s 16-bit isolation module. Together, they enhance the performance and versatility of the ScopeCorder family in applications including power systems, transportation, and mechatronics.
With the 720211 high-speed 100 MS/s 12-bit isolation module, up to eight units can be installed in a DL850E or DL850EV ScopeCorder, compared to a maximum of four for the previous units. This means that 1 kV 100 MS/s 12-bit isolation inputs will be available for up to 16 channels on a DL850E/DL850EV unit using the 720211 module.
Applications for the 720211 module are in the electric power and energy sectors, including testing and evaluation of inverters, power devices, and motors with high speed, high resolution, and high voltage. Multi-channel measurements are becoming a fundamental requirement for these applications to achieve advanced control.
The SENT 720243 monitoring module enables monitoring of SENT (Single Edge Nibble Transmission) communication protocols, which display data trends as an analog waveform, similar to existing LIN and CAN bus monitoring modules. In addition to monitoring data trends, the new module will also trigger SENT transmissions.
The SAE J2716 SENT protocol is a point-to-point framework for transmitting signal values from a sensor to a controller. It is designed to enable high-resolution digital data transmission at a lower system cost than standard serial solutions for in-vehicle data transmission. Typical applications include data communication between airflow sensors and ECUs (electronic control units).
Up to four 720243 modules (providing eight SENT transmission ports) can be installed in the DL850EV. Alternatively, two units can be installed together with a 720240 (CAN) or 720241 (CAN-LIN) module.
Applications for the 720243 modules include development and production testing for SENT applications.
The 720254 4-channel, 1 MS/s, 16-bit isolation module incorporates four isolated BNC inputs. By installing eight of these modules in a DL850E/EV, a standalone measurement system of up to 32 channels can be achieved. In addition to increasing the number of channels that can be installed on a single device, this also offers greater flexibility for the user in terms of the variety of modules that can be installed.
Each isolated BNC input has a maximum isolation voltage of 600 V (DC + AC peak) when combined with a 702902 (10:1) or 701947 (100:1) probe. The maximum permissible common-mode voltage is 300 V RMS (CAT II).
The 720254 is suitable for a wide range of multi-channel measurement applications, but particularly for isolated high-voltage measurements and long-term monitoring of power generators or multi-output power supplies. It is also ideal for dynamic analysis of ECUs and/or propulsion systems.
Like other members of Yokogawa's ScopeCorder family, the DL850E combines the features of a high-performance digital oscilloscope and a multi-channel data logger. It can capture and analyze both transient events and trends over time periods ranging from milliseconds to 200 days, storing the acquired data in the large acquisition memory, internal hard drive, and/or an external PC hard drive.
Flexible modular inputs allow the DL850E to combine electrical signal measurements, physical sensor parameters, and CAN/LIN serial bus data, giving engineers a comprehensive view of any application by synchronizing measurements of different types of electrical and physical signals. Individually isolated and shielded input channels provide high-resolution sampling rates, and Yokogawa's unique "dual capture" feature allows transient signals to be captured during long-term measurements by recording at two different sampling rates.
The ScopeCorders DL850E and DL850EV are equipped with a large, fast acquisition memory, allowing the storage of up to 2 gigapoints of data, and provide high sampling rates of up to 100 MS/s across multiple channels simultaneously. Yokogawa's unique history memory function allows users to isolate and examine waveform records individually for quick and detailed analysis.
The ScopeCorder DE850EV Vehicle Edition is designed for engineers working in the automotive and rail industries, combining electrical signal measurements, physical performance parameters acquired by sensors, and CAN or LIN bus data transmitted by the propulsion system management system.
A DC power option allows the DL850EV to be used in a vehicle, with power supplied by the vehicle's battery. This DC power option allows both AC and DC power supplies to be used together, ensuring a highly reliable power source. If AC power fails, the DL850V instantly switches to DC input without interrupting the measurement.
The quality and reliability of the ScopeCorders DL850E and DL850EV are backed by a standard 3-year warranty.
