Does manipulating the controls of an oscilloscope change the characteristics of the input signal being evaluated?
Can someone please explain this to me?
Thank you.

An oscilloscope is a tool for examining the signal. The electron beam in the oscilloscope's cathode ray tube is deflected by the varying electrical charges on the plates situated around the beam. These varying electrical charges are supplied by the signal. So the oscilloscope simply displays the effect of the input signal on the electron beam (as seen in the trace on the screen). It does not change the signal.Skye77 said:Does manipulating the controls of an oscilloscope change the characteristics of the input signal being evaluated?

An oscilloscope is a scientific instrument used to measure and visualize electronic signals, typically in the form of voltage over time. It is commonly used in physics, engineering, and other scientific fields.
An oscilloscope works by displaying a graph of voltage over time, typically on a screen. It does this by using a cathode ray tube (CRT) or a liquid crystal display (LCD) to create a visual representation of the electronic signal.
Oscilloscopes are often used in circuit design and troubleshooting, as well as in testing and analyzing electrical equipment. They can also be used in the fields of medicine and biology, such as in electrocardiograms (ECGs) to measure heart activity.
The horizontal axis of an oscilloscope display represents time, while the vertical axis represents voltage. The position of the signal on the screen indicates the voltage, and the distance between each wave or pulse indicates the frequency of the signal.
Some important features to consider when choosing an oscilloscope include bandwidth (the range of frequencies it can accurately measure), sample rate (how often it takes a measurement), and number of channels (how many signals it can measure at once). It is also important to consider the display type, size, and resolution, as well as any additional features such as triggering options and data storage capabilities.
