Yokogawa SL1000 High-Speed DAQ System Brochure

The Yokogawa SL1000 High-Speed Data Acquisition System represents a monumental leap forward in transient measurement and multi-domain signal capture technology. Designed from the ground up to meet the rigorous demands of modern engineering challenges—from cutting-edge power electronics development to sophisticated mechatronics validation—the SL1000 redefines what is possible within a portable, modular DAQ platform. Its core strength lies in its unprecedented combination of speed, channel density, and isolation integrity, ensuring that even the most elusive transient events are captured with pristine accuracy and without compromising channel safety. Engineers grappling with high-frequency phenomena that traditional oscilloscopes or slower data loggers simply miss now have a dedicated tool capable of continuous, high-fidelity capture across numerous synchronized channels. This system is not merely an evolution; it is a revolution in synchronized, high-speed data acquisition tailored for critical industrial and R&D environments where every microsecond and every volt matters. We invite you to explore the capabilities that make the SL1000 the benchmark for complex waveform analysis.

Featuring Extraordinary 100 MS/s Simultaneous Acquisition Capability.

At the heart of the SL1000’s superior performance is its market-leading sampling capability: a true 100 Mega-Samples per second (MS/s) sustained acquisition rate available simultaneously across every connected channel. This extreme speed is crucial for accurately analyzing high-frequency content inherent in modern switching power supplies, rapid mechanical vibrations, and complex digital communication protocols. Unlike systems that may offer high speed on only one or two channels, the SL1000 maintains this fidelity across its entire configuration, up to the maximum eight slots available. This capability allows engineers to capture the sharp rise and fall times of modern Silicon Carbide (SiC) and Gallium Nitride (GaN) semiconductor devices, ensuring that design margins are accurately assessed and overshoot phenomena are never missed. The integrated memory management, supported by the sophisticated GIGAZoom engine, ensures that this high-speed data stream can be managed efficiently, either stored internally or streamed externally without bottlenecks that compromise the integrity of the captured signal profile.

Isolated 12-Bit Modules Ensure Safety And Integrity.

Signal integrity and operator safety are paramount in high-voltage testing environments, and the SL1000 addresses these concerns through its robust library of plug-in modules, specifically highlighting the high-performance, 12-bit isolated measurement units. These modules are engineered to handle up to 1 kV of isolation, providing engineers the confidence to probe circuits with vastly different ground potentials, such as those found in three-phase inverters or battery management systems (BMS), without risking damage to the DAQ unit or the connected instruments. The 12-bit vertical resolution, combined with the high sampling rate, provides an excellent dynamic range, allowing for the simultaneous measurement of both minute signals (like sensor feedback) and large voltage transients (like bus ripple) with superior accuracy. This dual capability—high voltage handling coupled with high resolution—is a non-negotiable feature for effective power electronics design validation, where precise harmonic analysis often requires distinguishing subtle voltage variations within a high-noise environment.

Eight Slots Support Diverse Plug-In Module Requirements.

Modularity is the bedrock upon which the SL1000’s versatility is built. The system accommodates up to eight distinct plug-in modules within its compact chassis, providing unparalleled flexibility to configure specialized measurement setups on demand. The extensive library encompasses over twelve different module types designed to interface directly with the electrical and physical signals prevalent in modern engineering. This includes current transducers, high-voltage differential probes, strain gauge conditioners, thermocouple inputs, and digital bus acquisition cards (such as CAN/LIN). For complex mechatronics applications, an engineer can simultaneously connect high-speed voltage measurements, strain data from a structural component, and embedded bus traffic, all time-synchronized to the nanosecond level. This cohesive integration of disparate signal types within a single platform dramatically simplifies system validation, reducing setup time and eliminating the synchronization errors often associated with chaining multiple, disparate measurement instruments together.

Advanced Gigabit Ethernet Stream Data Seamlessly Now.

To handle the sheer volume of data generated by simultaneous high-speed acquisition, the SL1000 features best-in-class communication interfaces, headlined by integrated Gigabit Ethernet (GigE) and robust USB 2.0 connectivity. The GigE interface supports high-throughput, real-time data streaming directly to a supervising PC or server. This capability is indispensable for long-duration captures or scenarios where immediate analysis during the test run is required, effectively transforming the SL1000 into a network-enabled, high-speed acquisition node. Furthermore, the internal storage options, supported by the GIGAZoom engine, allow for continuous high-speed recording—up to $1.6 \text{ MS/s}$ per channel—to an internal hard disk, ensuring that no critical event is lost even if network communication is momentarily interrupted. This robust data handling architecture guarantees measurement continuity, whether analyzing slow thermal drift over days or capturing a single, rapid power failure event.

Power Electronics Testing Demands Superior Signal Fidelity.

For the exacting realm of power electronics testing—encompassing the characterization of Variable Frequency Drives (VFDs), DC-DC converters, and electric vehicle (EV) battery systems—the SL1000 is the unequivocal instrument of choice. The combination of high voltage isolation and high sampling frequency directly addresses the challenge of measuring switching transients, which often exhibit rise times measured in tens of nanoseconds alongside massive voltage swings. By accurately capturing the precise moment a pulse-width modulation (PWM) signal transitions, designers can analyze phenomena like dv/dt stress, overshoot magnitude, and harmonic content with precision. The system’s ability to capture these events across multiple phases simultaneously facilitates thorough analysis of power quality and efficiency metrics across the entire system architecture, providing the granular data needed to optimize switching frequencies and minimize electromagnetic interference (EMI).

Mechatronics Validation Benefits From Mixed-Domain Capture.

The complexity of modern mechatronic systems, particularly in automotive and aerospace sectors, demands measurement solutions capable of correlating electrical behavior with mechanical response. The SL1000 excels here by facilitating true mixed-domain testing. An application might require simultaneously monitoring the high-speed ignition voltage pulses, the corresponding torque sensor output (requiring low-frequency strain measurement), and the communication data packets flowing over the vehicle’s CAN or LIN bus. The SL1000’s modularity allows for the integration of all these signal types—fast electrical transients, slower physical responses, and digital protocols—into one unified, time-synchronized data file. This holistic view is essential for root cause analysis when diagnosing complex interactions, such as identifying how a momentary voltage sag affects a critical sensor reading or how mechanical vibration couples back into the control electronics.
