Getting Started The oscilloscope’s high-speed display can be used to isolate infrequently changing signals. You can then use the characteristics of these signals to help refine the trigger specification. For more information on triggering, data acquisition, data examination and measurement, and configuration, see the later chapters. Using the Oscilloscope, and Refining the Trigger Specification 1-3
