What does an oscilloscope do?
Oscilloscope is a kind of instrument which is widely used to display the trace change of instantaneous value measured.It can transform the electric signal invisible to the naked eye into visible image, which is convenient for people to study the change process of various electric phenomena. An oscilloscope USES a narrow beam of high-speed electrons to produce tiny points of light by hitting a surface coated with fluorescent material. Under the action of the measured signal, the electron beam ACTS like the tip of a pen and can plot the instantaneous value of the measured signal on the screen.Use oscilloscope to be able to observe all sorts of different signal amplitude the waveform curve that changes with time, still can use it to test all sorts of different electric quantity, if voltage, current, frequency, phase difference, adjust amplitude to wait a moment.
Analog and digital oscilloscope in the observation of the details of the waveform, which has the advantage?
1. Which is more advantageous, analog or digital oscilloscope, in looking at the details of the waveform (e.g., looking at parasitic waveforms of less than 1% at zero and peak crossing)?
2. Digital oscilloscope generally provides online display of root mean square value, its accuracy is generally what?
Answer: 1) observe parasitic waveform of less than 1%. The observation accuracy is not very good either in analog oscilloscope or digital oscilloscope. The vertical accuracy of the analog oscilloscope may not be higher than that of the digital oscilloscope. For example, the vertical accuracy of the analog oscilloscope with a certain 500MHz bandwidth is ±3%, which is not more advantageous than that of the digital oscilloscope (usually the accuracy is 1-2%). Moreover, the automatic measurement function of the digital oscilloscope is more accurate than the manual measurement of the analog oscilloscope for details.
