The Yokogawa DLM3054 is a 500 MHz mixed-signal oscilloscope that captures both analog and digital signals simultaneously. It delivers four analog channels plus an optional 8-bit logic analyzer, enabling observation of 11 total channels (3 analog + 8 logic). With a maximum sample rate of 2.5 GS/s and record lengths up to 500 Mpts (optional), this instrument excels at resolving complex waveforms in embedded systems, power electronics, and automotive applications. A fully digital trigger engine minimizes timing jitter while supporting 13 trigger modes including edge, pattern, pulse width, runt, and serial bus protocols. The 8.4-inch XGA touch display and dual-zoom processor enable rapid analysis across up to 500 Megapoints, while 30 simultaneous automated measurements and 100,000-waveform history function streamline debug workflows.
