3. An oscilloscope is a laboratory
instrument commonly used to display and
analyze the waveform of electronic
signals. In effect, the device draws a
graph of the instantaneous
signal voltage as a function of time.
4. Dual Beam
5. A cathode ray oscilloscope is a very important
electronic measuring Instrument.
It is used to display and measure electrical
signals , Time intervals and phase shift between
two electrical signals non electrical Quantities
such as Pressure , strain and temperature can be
measured by first converting them into an
equivalent voltage using appropriate Transducer.
The internal section of an oscilloscope Vary
depending on the model and manufacturer.
6. i. Cathode ray Tube(CRT)
ii. Time Base Circuit
iii. Trigger Circuit
iv. Vertical Deflections System
v. Horizontal Deflections System
vi. High voltage Power Supply And,
vii. Low Voltage Power Supply
7. Originally all oscilloscopes used cathode ray
tubes as their display element and linear
amplifiers for signal processing.
but modern oscilloscopes can have LCD or
fast analog-to-digital converters and digital
9. The cathode ray tube (CRT) is a vacuum
tube containing an electron gun (a source of
electrons) and a fluorescent screen, with
internal or external means to accelerate and
deflect the electron beam, used to create
images in the form of light emitted from the
11. A typical oscilloscope has a display screen,
numerous input connectors, and control knobs
and buttons on the front panel.

Measurement of voltage and current .
Measurement of phase and frequency.
In addition to the amplitude of the two
oscilloscope can show distortion and
13. One of the advantages of a scope is that it can
graphically show signals: where a voltmeter
may show a totally unexpected voltage.
distortion is very small.
Very fast instrument.
Storage scopes are helpful for "capturing"
rare electronic events that cause defective
