SL2000 High-Speed Data Acquisition Unit

High-Speed Modular Data Acquisition for Automated Test Systems

The SL2000 is a high-speed, modular data acquisition system that combines the functionality of an isolated oscilloscope with the flexibility of a high-speed DAQ, ideal for design validation, ATE systems and operational testing.

Compatible with the same plug-in modules as the DL950 ScopeCorder, the SL2000 offers exceptional versatility for mixed-signal measurement. A single unit can simultaneously capture a wide variety of signals, including high voltages, vehicle communication busses, and NVH inputs such as vibration, strain, and temperature.

Engineered for ATE Systems

The SL2000 is a 4U-high, high-speed data acquisition system and modular isolated oscilloscope designed for high-channel-count automated testing and validation.

By integrating a wide range of plug-in modules, the SL2000 enables both transient capture and long-duration, multi-channel recording of diverse signal types including voltage, current, temperature, acceleration, strain, frequency, digital I/O, and automotive communication protocols such as CAN, CAN FD, LIN, and SENT.

Two Operation Modes: Scope and DAQ

Scope Mode: For high speed, repetitive signals. Works like an oscilloscope:

Captures waveforms on trigger using T/Div and sampling settings
Displayed with V/Div scaling

DAQ Mode: For long-duration, continuous recording. Functions like a data logger:

Records with defined sampling intervals and total duration
Displayed using absolute upper and lower limits

Scalable to 160 channels with IS8000 software

Capture signals at speeds up to 200 MS/s, and scale to 160 synchronized channels (/C50) by linking as many as five chassis as a single triggered unit.

Even higher channel counts are possible through custom integration.

Flexible Control Software Options for Test Automation

Choose the approach that fits your workflow. IS8000 software offers a no-code, configurable solution for rapid instrument setup, data capture, and visualization, ideal for standardized test environments and where ease of use and long-term supportability are key.

For fully customized systems, Yokogawa's open API and sample code enable seamless integration into your bespoke ATE software for precise control and data streaming.

Extensive Trigger Library & GO/NO-GO Logic

Sophisticated triggering and automated test decisions help streamline pass/fail evaluation and event-driven acquisition.

Flexible trigger modes: Auto, Normal, Single, On-Start, and time-based triggers
Trigger from any source: analog, logic, math channels, external signals, or scheduled time
Advanced conditions: edge, pulse-width, A→B(N), wave-window, and power anomaly triggers
GO/NO-GO actions: save data, trigger alerts, or send email based on waveform evaluation
Dual-capture and long-memory support for simultaneous transient and trend analysis

Hardware-Accelerated Math & Analysis

Built-in computation capabilities allow real-time analytics without external post-processing or slowing down acquisition.

User defined and real-time math channels (/G02 and /G03): perform waveform calculations such as integration, filtering, RMS, PWM, combined waveform math and custom operations
Power analysis (/G05) for voltage/current, harmonics, power factor, and efficiency
Motor dq analysis (/MT1): Park/Clarke transforms with speed, torque, and rotor position outputs

Advanced Real-Time Analysis

With optional functions such as real-time math (/G03), power calculations (/G05), and motor dq analysis (/MT1), the SL2000 can perform on-the-fly waveform computation, power analysis, and motor control vector analysis. Trigger conditions can also be set based on computed math results.

8 G points large memory (/M2 option)

With up to 8 G points of memory and 20 seconds of continuous capturing, even at 200 MS/s, no signal changes are missed.

*Up to 4 G points of memory is allocated per channel.

8 G points large memory (/M2 option)

SSD recording (/ST1 or /ST2 option)

The 512 GB internal SSD can record for long periods of time at up to 2 MS/s. Waveforms from dual capture can also be recorded, which is useful for in-vehicle endurance testing and capturing rare spontaneous events.

SSD recording (/ST1 or /ST2 option)

Flash acquisition (/ST2 option)

Long time recording at up to 20 MS/s, which is 100 times faster than the previous model, is available. You can capture data anywhere you cannot bring a PC such as on-vehicle or field testing. The flash memory is non-volatile, so the captured data stays in the instrument even after turning off the power. Data can later be transfered to a PC.

Flash acquisition (/ST2 option)

Multi-sample rates

Sample rates can be set by channel. Reducing the sample rate reduces the amount of data even when modules with high and low sample rates are mixed together. This allows for less memory space to be used and improves the transfer speed.

Multi-sample rates

• Built-in SSD 512 GB
• SD Memory Card (SD/SDHC/SDXC)

• USB Storage up to 8 TB

2-motor/4-motor system test for EV

In Hybrid Electric Vehicle (HEV) development, two or four motor systems, with each motor connected to a driving wheel, are commonly used. This design eliminates traditional powertrains, simplifying the overall system and alleviating concerns when driving a 4WD on snowy roads. The multi-channel, high-speed, isolated SL2000 can simultaneously capture and analyze signals from these multi-motor setups.

Distributed energy resource test (renewable energy)

Renewable energy sources like hydro, solar, and wind power are integrated into the power grid, driving the transition to a sustainable society. The DL950/SL2000 supports this transition with its long-term power recording and analysis capabilities. For example, wind turbines require synchronized monitoring of power generation efficiency at multiple locations, which can be achieved with high precision using GPS or IRIG signals.
Additionally, the DC/AC conversion efficiency of solar panel-generated DC power can be accurately measured using the WT5000 precision power analyzer, while the waveform data from the DL950/SL2000 can be seamlessly integrated with the WT5000’s measurement data to provide a comprehensive analysis of inverter performance.

Vibration and Acoustic Analysis

Vibration is inherent to "moving objects" such as motors and engines. Analyzing the frequency of vibrations to identify abnormal areas is an essential test in the development of "moving objects." By using multiple acceleration modules, Vibrations at multiple points can be simultaneously captured and up to eight vibration frequencies can be analyzed using FFT functionality to identify faulty components.

Railway Vehicle Running Test

By using the DL950 and SL2000, we can simultaneously record the voltage, current, and rotational speed of the battery, inverter, and drive motor, as well as the vibration and interior temperature of railway vehicles.

Simultaneous measurement of remote devices with a synchronization accuracy of ±150 ns (typ) when using the /C40 option.
Distributed synchronous measurement with up to 160 channels
Simultaneous recording of strain and sound (using voltage output microphones or sound level meters) is also possible
Using power calculations and motor dq analysis, power efficiency and motor performance can be evaluated.

Vehicle Serial Bus Data Recording and Driving Trajectory Display

You can simultaneously view the trends of physical values from CAN/CAN FD bus data alongside the corresponding measured waveforms on the same screen. For example, you can verify the correlation between the ON/OFF signal of the ignition switch, the corresponding CAN/CAN FD signal, and the actual signals from related pressure sensors, all on the same screen. By connecting a GPS unit, Latitude, longitude, altitude, speed, direction, and time information can be added to the measurement data. Using DIAdem, you can simultaneously display the measurement data and driving position. With IoT gateways or M2M routers, remote control and data monitoring can be performed wirelessly.
