Mixed Signal Oscilloscopes

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.


Capture, analyze, and troubleshoot electrical or real-world physical signals. Oscilloscopes observe the change of electrical signals over time, continuously graphed on a display as voltage or amplitude vs. time.
