The Yokogawa DL9705L is a mixed-signal oscilloscope combining analog and logic channel capabilities for embedded system debugging and high-precision waveform measurement. It integrates four analog channels with 500 MHz bandwidth and up to 32-bit logic inputs, delivering acquisition depths to 6.25 M points per channel and sampling rates up to 5 GS/s in interleave mode. The Advanced Data Stream Engine (ADSE) minimizes dead time, enabling waveform update rates to 2,500,000 waveforms/sec in N Single Trigger Mode. With 32-bit logic triggering, configurable threshold levels, and history memory for 2,000 waveform screens, this instrument supports edge-qualified, state, and logic-based triggers up to 250 MHz toggle frequency on digital inputs. Eye pattern analysis, automated measurements, and waveform computation functions enable detailed characterization of complex signals across analog and digital domains.
