1. Oscilloscope

3. • Oscilloscope fall in two main category
one is analogue oscilloscope and second
is digital storage oscilloscope.
• Oscilloscope develop with the cathode
ray tube (CRT) technology.
• Cathode ray tube (CRT) have high
frequency response.
• So lets look at the CRT first.
• CRT simply shows the electron beam on
phosphor coated screen.
• CRT basically consist of electron gun,
vertical and horizontal deflection system
and acceleration section.
• So the oscilloscope circuit move the
electron beam to the phosphor coated
screen so the glow trace a path of the
beam and it is visible for a short time.
• Oscilloscope are often use for rise time
measurements.

5. • Oscilloscope is use for measuring
frequency, width and period.
• Oscilloscope display amplitude of
signal in function of time.
• Both analogue and digital
oscilloscope have 2 to 8 channels.
• Analogue oscilloscope have no
memory storage and digital
oscilloscope have some memory
storage.
• If we want to check voltage spike or
to check time interval accuracy we
use oscilloscope.
• In modern oscilloscope there is
VLSI circuits.
• Modern (digital) oscilloscope are
costlier than analogue oscilloscope.
