Yokogawa DLM5034 Mixed Signal Oscilloscope: 4-Channel, 350 MHz

The Yokogawa DLM5034 is a 4-channel mixed-signal oscilloscope that merges digital oscilloscope and logic analyzer capabilities into a single instrument. It simultaneously captures analog signals across 4 channels and digital logic states across 16 or 32 bits, enabling comprehensive debugging of complex electronic systems. With 350 MHz bandwidth, 2.5 GS/s sample rate, and up to 1 Gpoint optional memory, the DLM5034 delivers extended capture windows and precise signal characterization.

The instrument features 12-bit vertical resolution (16-bit in High Resolution Mode), 14 configurable low-pass filters per channel, and vertical sensitivity down to 500 μV/div on 1 MΩ inputs. Vertical axis resolution reaches 12-bit maximum standard configuration, expandable to 16-bit in specialized modes.
