Mixed Signal Oscilloscopes

The design, validation, and manufacturing of modern electronics necessitate the measurement of both analog and digital signals. Mixed signal oscilloscopes enable the simultaneous, time correlated observations and analysis of analog with digital (logic) signals, to establish causal relationships between the various areas of a device's electronics. They are purpose built tools for troubleshooting electrical anomalies, measuring parametric values, and monitoring cause and effect relationships between signals.

From our first digital oscilloscope in 1988 and over ten generations since, Yokogawa oscilloscopes have enabled engineers to maintain high sample rates for long observation periods with deep, segmented acquisition memory. Yokogawa oscilloscopes offer extensive signal analysis capabilities, dedicated analysis and decode of serial buses such as I2C, SPI, CAN, LIN, CXPI and FlexRay, improved ergonomics, and value.

8 channel mixed-signal oscilloscopes for every engineer in bandwidths of 350 MHz or 500 MHz. Best-in-class performance in usability, acquisition, analysis, and display.

Get enhanced productivity in a small footprint touchscreen oscilloscope. Design and validate advanced serial bus, power supply, and electromechanical systems with this feature-filled oscilloscope that can be configured at very affordable prices. Bandwidth from 200 MHz to 500 MHz for up to four low-noise input channels.
