Oscilloscope
Definition of Oscilloscope :
Oscilloscope
is an electrical Instrument through which we can observe and measure the
different wave forms and graphically behavior of Electrical Circuits.There
are two types of Oscilloscope one is Analog and second is Digital.In
Analog Oscilloscope we need to perform mathematical calculations to measure the
actual values of Wave form.In Digital
Oscilloscope we no need to perform any Mathematical calculation to measure the
actual values of wave form.Today I
will tell you the detail usage of Analog Oscilloscope.
Basics
of Oscilloscope:
Oscilloscope
shows the 2-Dimensional graphical view. For
2-Dimensional graphical view there are two axis in Oscilloscope one is
X-axis and other is Y-axis. we can adjust the position of wave on X & Y
axis by vertical and horizontal position probes.
X-axis
shows the time period of the current wave form as Time per Division.
Y-axis
shows the Amplitude of voltage of current wave form as Volt per Division.
There
are commonly two basic channels in Oscilloscope. From two different channels we
can observe two different wave forms from two different input sources. For both
channels Time axis is same but Volt axis for both channels are different. The
reason is that time on time per division for both wave is same but the
voltage’s amplitude can be different of both waves.
