It features a rich front and rear I/O panel and is engineered for standalone or rack-mounted deployment—perfect for embedded debugging, automated testing, and complex validation workflows.
Packed with analysis functions such as serial bus decoding, Bode plotting, mask testing, and memory waveform comparison, the SDS5058L offers capabilities normally found in higher-cost oscilloscopes. Its ability to handle large volumes of data from multiple channels makes it ideal for power systems, industrial automation, motor control, and multi-core embedded system analysis.
Whether in product development, production testing, technical service, or engineering education, the SDS5058L stands out as a robust and scalable measurement solution for modern electronic challenges.
Power-Up Sequence Analysis

Modern electronic systems often contain multiple chips and modules that must power up in a specific sequence to avoid conflicts and ensure stability. Errors in this sequence—especially in communication systems—can lead to data failures. As circuits grow more complex, power-up testing becomes more challenging. The SDS5000X HD captures all relevant signals in a single acquisition, enabling efficient, accurate one-shot measurements—even in systems with up to 8 power rails—saving time and reducing errors.
Three-Phase Power Analysis

An 8-channel oscilloscope enables full three-phase power analysis by measuring all voltage and current signals simultaneously. It captures real-time waveforms, shows phase relationships for balance checks, and performs harmonic analysis using FFT. Optional software adds vector diagram testing, power quality, ripple, and efficiency analysis for motors and power systems.
