Abstract

An electrical signal is an electrical voltage or current that carries information. The term electrical signal in
a circuit can refer to voltage or current. Voltage or often people call with potential differences, is the energy
carried out to move a single charge, while an electric current is a change in the speed of a charge with
respect to time or charge that flows in units of time. In a research or scientific project, measurement tools
are often needed that can project the form of electrical signals to be seen and studied. One measuring
instrument commonly used is the oscilloscope (oscilloscope). Oscilloscopes are usually used to observe the
exact wave shape of an electrical signal. This measuring instrument works based on data samples, the higher
the data sample, the more accurate the electronic equipment. Oscilloscopes usually have very high data
samples, so Oscilloscopes are very expensive electronic measuring devices. If an oscilloscope has a sample
rate of 10 Ks / s (10 kilos of sample / second = 10,000 data per second), then this tool will read 10,000 times
a second. However, not all scientific research or projects require a type of Oscilloscope that has such a high
level of accuracy, there are some of them needed just to learn a basic introduction to electrical signals, there
are several other cases needed to be practically portable, so it is easy to use at the time is required. But in
the market today, Oscilloscope products are dominated by products of manufacturing manufacturers with
large and heavy dimensions, of course with relatively very expensive costs and generally for the needs of
laboratory procurement.

Keywords: Oscilloscope, Electrical Signal, Portable, Electronic Measuring Instruments.
