Oscilloscopes, also called Digital Storage Oscilloscopes (DSOs) or Mixed Signal Oscilloscopes (MSOs), are a common type of test instrument used to 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. During observation, oscilloscopes can analyze waveforms parametrically (i.e. frequency, RMS, peak-to-peak amplitude, rise time, etc.) Non-electrical signals, especially mechatronic signals such as vibration, strain, temperature, or current can be converted to voltages and displayed.

Yokogawa oscilloscopes deliver a range of bandwidths, the world's only eight channel and sixteen channel (plus logic) oscilloscopes, unparalleled suites of triggers and signal analysis, and a unique ability to save multiple triggered-events to "History" memory.
