The Yokogawa DLM3034 is a 350 MHz mixed-signal oscilloscope engineered for comprehensive signal analysis across analog and digital domains. This 4-channel instrument combines a 12-bit analog front end with 8-bit logic inputs, delivering up to 2.5 GS/s sampling rates and 1 Gpts maximum record length. The 8.4-inch XGA touchscreen display and dual independent zoom processors enable rapid signal inspection and detailed waveform analysis in laboratory and field environments.
