Virtual Oscilloscope | Academo.org - Free, interactive, education.
An oscilloscope is a useful tool for anyone working with electrical signals because it provides a visual representation of the signal's shape, or waveform. This allows you to measure properties of the wave, such as amplitude or frequency. The initial signal above is a 200Hz sine wave, which has an amplitude of 5 volts.
Sine wave basics and applications in oscilloscopes
2014年10月24日 · Consider the pure sine wave in the illustration from a Tektronix MDO3104 oscilloscope. It is derived from the scope’s internal function generator, set at 60 Hz. What is notable and also the defining characteristic of this sine wave is that the greater the amplitude as a positive or negative value, the slower the rate of change.

Phase is best explained by looking at a sine wave. The voltage level of sine waves is based on circular motion. Given that a circle has 360°, one cycle of a sine wave has 360°, as shown in Figure 10. Using degrees, you can refer to the phase angle of a sine wave when you want to describe how much of the period has elapsed.
How to Read an Oscilloscope Screen – Things You Should Know
1. Sine Waves. The sine wave is the most basic and pure waveform, used widely in electronics and signaling. For example, AC power supplies and radio transmitters output sine wave signals. On an oscilloscope, a sine wave will appear smooth and continuous, oscillating above and below the horizontal axis.
How to Use an Oscilloscope - SparkFun Learn
Most scopes produce a two-dimensional graph with time on the x-axis and voltage on the y-axis. An example of an oscilloscope display. A signal (the yellow sine wave in this case) is graphed on a horizontal time axis and a vertical voltage axis.
Example Waveforms that you will frequency see in an oscilloscope
A sine wave is one of the most common waves you’ll see in an oscilloscope. A sine wave describes a continuous and smooth periodic oscillation. In comparison, the square wave, that you’ll see next, switches from one voltage level to another very abruptly.

2022年4月29日 · One common pattern you'll see is this smoothly undulating, snake-like up-and-down trace, which is called a sine wave or sinusoidal wave (green upper line). Another quite common pattern is a sawtooth wave (the blue stepped trace shown underneath the sine wave).
Capturing and Analyzing Waveforms Portable Oscilloscopes
With the right scope, you can eliminate a lot of button pushing and knob twisting, and capture an unknown waveform in just a few steps. With a Fluke ScopeMeter, follow these simple steps to get to a good starting point: Observe and follow all safety regulations. Know your test tool operation and specifications.
