What is an oscilloscope?
The oscilloscope is basically a graph-displaying device – it draws a graph of an electrical signal. In most applications, the graph shows how signals change over time. Oscilloscopes can be classified in two major categories – analog and digital types. Digital oscilloscopes can be classified into digital storage oscilloscopes (DSOs), digital phosphor oscilloscopes (DPOs), mixed signal oscilloscopes (MSOs), and digital sampling oscilloscopes.
Oscilloscopes are used for many measurements including:
- Voltage Measurements
- Time and Frequency Measurements
- Pulse Width and Rise Time Measurements
- Phase Shift Measurements
