Yokogawa Test & Measurement has introduced the fourth generation of its high-speed data acquisition system, designed for use in power systems, automotive applications, and mechatronics.
The new SL2000 High-Speed Data Acquisition Unit, part of the ScopeCorder series, merges the capabilities of a mixed-signal oscilloscope and a data recorder. It’s built to capture both rapid signal changes and long-duration data trends. This rack-mounted, modular system is intended for research and development, validation, and diagnostics, and operates in conjunction with a PC. Its predecessor, the SL1000, debuted in 2007.
The SL2000 shares its architecture with the DL950, featuring a central FPGA that directs data flow through the system. A secondary FPGA, integrated on the same chip, manages real-time calculations like integration and differentiation. A dedicated CPU running a proprietary multicore OS controls the entire system, according to Michael Rietvelt, Yokogawa’s product manager.
Yokogawa’s new SL2000 system supports over 20 different modules, allowing connection to sensors measuring voltage (up to 1000V), current, torque, vibration, and temperature. It also interfaces with CAN, CAN FD, and LIN buses, enabling synchronized data acquisition at speeds of up to 200 mega-samples per second across eight slots. This setup supports up to 32 analog or 128 digital channels, with a memory capacity of 8 Gpoints and the ability to stream data directly to a PC.
The system is designed for high-precision testing, incorporating features like a high-voltage differential probe and a dual current power analyzer for motor control. Yokogawa is also collaborating with European developers working on digital twin technology.
According to product manager Michael Rietvelt, the SL2000 can be controlled via the IS8000 PC software, although Yokogawa expects users will split evenly between using their software and integrating with custom solutions. To support this, the system includes APIs for Python, LabVIEW, and C, providing flexibility for system integration and automation.
Due to a 7.5% reduction in power consumption (now at 280 VA), some older SL1000 modules are not compatible with the SL2000. Rietvelt emphasized that careful attention was paid to signal integrity in the design, with specialized shielding and mechanical engineering to meet the demands of energy-efficient applications.
The SL2000 allows simultaneous measurement of both slow-changing mechanical signals like temperature and vibration, and high-speed control or electrical signals, all in sync. Real-time math functions can be used to trigger data capture based on specific features, such as signal differentiation or power consumption analysis.
Up to five SL2000 units can be synchronized in a 19-inch rack using optical transceivers. Data can be streamed directly to a PC at speeds up to 320 MB/s via Flash acquisition or 10 Gbps Ethernet, supporting real-time streaming at rates up to 20 MS/s without buffering.
The system comes with comprehensive PC software tools for testing and evaluation. This includes free APIs (for free-run, trigger-based, and Flash acquisition modes), a LabVIEW driver, and a single license of IS8000 software with advanced DAQ capabilities. Sample programs are available in Python, C#, and VB, and a Classic Data Viewer (IS8002CDV) is provided for remote access. Additional tools such as a USB driver, TMCTL library, and MATLAB toolbox will be released later.
The SL2000 is available now, with shipments expected to begin by late Q2 or early Q3.
