  1. Analog oscilloscope and a digital oscilloscope - What is it and what else is there? Oscilloscopes have been established since the beginning of the 20th century for the measurement and analysis of a wide range of electrical signals - at that time still known as galvanometers. The word oscilloscope is composed of the ancient Greek skopein (to look at) and the Latin oscillare (to rock). High-frequency electrical signals from televisions, radios and computers are made easily visible with these devices and now the digital oscilloscopes have almost completely replaced the analog version of the market. Other types of oscilloscopes include CCD oscilloscope, mixed-signal oscilloscope, or the more specialized waveform monitor (WFM) in the field of video technology. Structure and mode of operation Analog oscilloscopes use a classic cathode ray tube, whereas digital devices use LDC technology. For digital oscilloscopes, it may, therefore, be the case that the display is larger or even colored. For modern digital oscilloscopes, such a representation is no longer a problem for the better differentiation of the channels. Since with an oscilloscope, especially the temporal voltage curve is of interest, both analog and digital devices, on the one hand, show the voltage signal, on the other hand, the electric current, the frequency, phase shifts, continuity characteristics or pulse diagrams. Digital storage oscilloscopes also feature pre-triggering, multi-value analysis software, averaging, mathematical functions, frequency spectra, statistics, and histograms. Furthermore, the digital storage oscilloscope (DSO) can easily enlarge the view. Scrolling is also possible. Advantages and disadvantages of the analog oscilloscope Due to the built-in cathode ray tube, the difficulty of an analog device quickly becomes apparent here: orthogonal errors, edge blur, pincushion errors and non-linearities are considered classic disadvantages. Added to this is the size of the invention. Advantages and disadvantages of the digital oscilloscope The digital storage oscilloscope (DSO for short) offers some more benefits. It is much smaller in size, no longer requires an inefficient cathode ray tube, but works with LCD technology in an energy-efficient manner, and the display of measured data is more accurate and better. Last but not least, faster processors convince with these devices. Also, modern digital oscilloscopes operate with more advanced signal analysis capabilities, making them unquestionably powerful. Analog or digital - For which purposes is which oscilloscope suitable? DSOs are ideal for high-frequency signals today. With these devices, more extensive functions, signals and frequencies can be recorded efficiently, stored and analyzed. An analog oscilloscope saves the image instead of the signal on the tube, which is far from the case with DSOs. Buy the best oscilloscope but before that read the reviews here in
