DIGITAL STORAGE OSCILLOSCOPE "DSO"

PURPOSE
An oscilloscope is an indispensable instrument for viewing electrical signals.
The advantage of a digital oscilloscope is that the measured signals can be
frozen for subsequent examination or comparison with other signals. In
digitizing the signal there is the additional advantage that it can also be
scientifically analyzed. Thus the calculation of RMS values is no problem,
although remember that the displayed RMS value is only for the AC
component of the measured signal. By using the markers the signal frequency
can be determined (by measuring the time of one period), and the voltage can
also be measured between the two markers.
When using a digital oscilloscope, it should be remembered that the signal to
be measured is split up piece-wise, i.e. into "samples". The result of such
splitting is that certain signals may escape the sampling frequency, especially
in the case of high frequency signals.
