S9681DB-0 | Yokogawa High-Performance 4-Channel Digital Oscilloscope

Product Description

The S9681DB-0 (S9681DB-0) is an advanced digital oscillography solution engineered for precision signal analysis in high-frequency electronic environments. Designed for research and development, telecommunications, and complex circuit debugging, this 4-channel instrument provides the necessary bandwidth and sampling density to capture transient phenomena with high fidelity. By utilizing a 10-bit vertical resolution architecture, the S9681DB-0 (S9681DB-0) offers significantly higher signal detail compared to standard 8-bit systems, allowing for the detection of subtle noise and quantization artifacts in high-speed data streams.

The unit features a robust triggering engine, supporting complex logic, pulse width, and video-specific triggers. Its compact 80mm height profile makes it suitable for rack-mount integration or high-density benchtop use. Built to withstand industrial conditions, it operates reliably across a wide temperature range, ensuring stable measurements even in non-climate-controlled testing facilities.

Application & Laboratory Integration

The S9681DB-0 (S9681DB-0) is a primary tool for engineers working on high-speed serial bus analysis, power integrity testing, and RF component characterization. Its 2 GHz bandwidth is particularly effective for troubleshooting LVDS, HDMI, and DDR memory interfaces where fast rise times require high-frequency response to avoid signal rounding and inaccurate jitter measurements.

FAQ

Does the S9681DB-0 support active probes for high-impedance testing?Yes, the S9681DB-0 (S9681DB-0) is compatible with Yokogawa’s range of active and differential probes. Utilizing active probing is recommended for 2 GHz measurements to minimize circuit loading and maintain signal bandwidth at the probe tip.

How does the 10-bit resolution benefit my measurements?Compared to 8-bit oscilloscopes, the S9681DB-0 (S9681DB-0) provides four times the vertical resolution. This allows for more precise measurements of small signal components riding on top of larger DC offsets, which is essential for power rail ripple analysis and sensor signal conditioning.
