Yokogawa DLM3024 200MHz Mixed Signal Oscilloscope

The Yokogawa DLM3024 is a 200 MHz mixed-signal oscilloscope purpose-built for electronic circuit design, testing, and debugging. It delivers four analog channels plus selectable 8-bit digital input on channel 4, enabling true 11-channel mixed-signal analysis. The instrument combines a large 8.4-inch TFT color touchscreen, deep memory architecture, completely digital triggering, and a redesigned analog front-end to capture complex signal interactions with high fidelity and minimal noise.
