OSCILLOSCOPE

The oscilloscope is essentially a graphic display device, which allows the representation of electrical phenomena, whose trend over time is reproduced on a luminescent screen. Of these phenomena, amplitude, duration and frequency can be essentially detected.

Insights

By using special transducers, almost all physical phenomena can be turned to electrical signals, and are therefore measurable with this instrument.
In summary, the oscilloscope is a graphical display device that represents electrical signals that vary over time. The vertical axis represents tension, while the horizontal axis represents time.
The oscilloscope works thanks to four steps: the analog conditioning, sampling and conversion in numerical sequence of the measured signal; the storage of samples; the numerical processing; the visualization on the screen through the oscillogram of the signal.
The main innovation lies in the time decoupling between the signal and the visualization. This is done by a raster display, which makes the time required to trace the image independent from the complexity of the image.
The evolution of electro-optical technologies has made the visualization possible without a vacuum tube.
The features brought by flat screen displays are the reduction of depth, weight and power consumption, and the organization of the screen in pixels. The main advantages are the ability to store multiple signals for long intervals of time, a stable visualization even at low frequency, the ability to measure the signal in the direct and automatic time domain; the ability to easily document the measurements, the ability to carry out self-calibration and self-diagnosis tests.
