Modern electronic systems incorporate various chips and modules whose initialization and operation may interfere with each other. Power-up sequence testing ensures that signals from different circuit modules follow the correct timing to avoid conflicts and guarantee system stability. For example, improper power-up sequences in communication systems can lead to data transmission errors. As circuit complexity increases, so do the challenges of power-up testing. The SDS5000X HD captures the entire power-up process of all relevant signals in a single acquisition, reducing measurement time, improving efficiency, and minimizing errors caused by repeated tests. For complex circuits with 8 power rails, this capability enables one-shot measurements.
