An oscilloscope with a 200MHz bandwidth and 2 channels is a type of test and measurement device that is used in electronics, engineering, and various scientific fields to visualise, measure and analyse electrical signals.
The 200MHz bandwidth represents the range of frequencies the oscilloscope can accurately measure and display. A 200MHz oscilloscope can accurately display signals with frequencies up to 200 million Hertz (cycles per second). This level of bandwidth is suitable for a wide range of applications, including high-frequency analogue and digital signals.
2 Channels refers to the oscilloscopes two input channels, which allows you to simultaneously measure and display two different electrical signals on the screen. This feature is particularly useful when you need to compare and analyse multiple signals, such as voltage waveforms or current waveforms, in real-time.
