Vertical Sensitivity
The graph on the screen of the oscilloscope shows the relation between the values of the voltage
and time. If the amplitude of the input voltage is greater, a higher range of the vertical amplifier
must be set. Depending on the amplitude of the signal, for a better visual result an appropriate
vertical amplifier is used. The ability to change the scale of amplification of the signal enables
the oscilloscope to show signals with very high amplitudes as well as signals with very low
amplitudes. The appropriate value of the amplification depends on the amplitude parameters of
the signal observed. The same signal would be shown differently depending on the degree of
amplification. A larger range is used when the amplitude of the whole signal needs to be shown.
A smaller range is used when, is need to make a detailed observation of the shape and the
amplitude parameters of separate sections of the signal. In such cases, when the signal is of
higher voltage, only a part of the signal is visible on the screen.
