A mixed signal oscilloscope is an instrument enabling 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.
