The Yokogawa DL1540CL is a portable 4-channel digital oscilloscope engineered for demanding signal capture and waveform analysis in laboratory and field environments. Combining a 6.4-inch color TFT LCD display with 150 MHz analog bandwidth and 200 MS/s maximum sampling rate, the instrument delivers reliable acquisition of transient and repetitive signals across a wide range of measurement scenarios. Its compact form factor—216 × 268 × 278 mm, 5 kg—facilitates mobility without sacrificing analysis depth or display clarity.

– Key Features
• Color Accumulate: Visualizes signal incidence distribution by color intensity, enabling rapid identification of jitter characteristics and anomalous event detection.
• P-P Compression: Renders maximum and minimum values within fixed screen intervals, maximizing visible waveform detail across extended time windows.
• History Memory: Preserves captured waveforms to prevent loss of transient anomalies that would otherwise vanish from the display.
• Snapshot Mode: Accumulates unlimited waveform overlays for statistical analysis and signal variation assessment.
• Envelope Mode: 100 MS/s sampling independent of time-base setting.
• Repeat Measurement Memory: Up to 100 k words for sequential signal capture during extended test cycles.
• Advanced Triggering: Edge, pulse width, TV line, TV field, event, logic, and delay trigger types.
• Pulse Counting Function: Automated pulse enumeration within user-defined intervals.
• I2C Bus Analysis (Optional): Support for bus transfer rates to 400 kbps with protocol-level data extraction and trigger integration.
– Compatibility & Integration
• GP-IB Interface: IEEE std. 488.2-1987 compliant; enables PC control, remote instrument operation, and external printer connectivity for automated test environments.
