The Yokogawa DL9140 is a 1 GHz bandwidth digital oscilloscope delivering 5 GS/s sampling across four channels. Built for precision measurement in engineering, system integration, and laboratory environments, it captures complex waveforms with 8-bit vertical resolution and up to 100 Mpoints record length per channel. The instrument combines fast acquisition with advanced triggering—edge, glitch, window, logic, pattern, runt, and setup/hold detection—enabling detailed signal analysis from DC to high-speed digital circuits.
