How To Learn Electronics :
Theory must be studied once and
referred to, again and again as you do
practicals. One is by building DIY
projects and then modifying them. Also
Repair of equipment, troubleshooting,
testing and calibrating. Then you know
how components behave and real life
limitations. Now design and engineer a
product and test it at customer site.
do a pilot production and test with
more clients. Now you will learn to
think based on practical applications.

- I will not Test Live Powered
equipment in the Ohms Mode.
- I shall not Measure Mains
Voltage in The Current Mode.
- I shall get it calibrated once a

it to my best friend.
- I can remember Red is Positive
and Black is negative.
- I will wear shoes and stand on a
block of wood while i test.
- I shall not operate the rotary
range switch at high speeds.
- I shall replace the
- I shall not accidentally keep
the hot-iron near the DMM or
- I shall not keep DMM on tall
table and pull it with the leads.

Oscilloscopes in Test
The usefulness of an oscilloscope
is not limited to the world of
electronics. With the proper
transducer, an oscilloscope can measure
all kinds of phenomena.
Tektronix oscilloscope. This was a
popular analog oscilloscope,
portable, and is a representative
example. - XYZs
of Oscilloscopes - Tektronix
to Oscilloscope - The
single most important diagnostic
tool used by experimental physicists
is the oscilloscope. Certainly all
scientists and engineers should be
familiar with this common
instrument, shown in the Fig. 1. An
oscilloscope (scope for short) can
be used to "see" an electrical
signal by displaying a replica of a
voltage signal as a function of
used to observe the change of an
electrical signal over time, such
that voltage and time describe a
shape which is continuously graphed
against a calibrated scale. The
observed waveform can be analyzed
for such properties as amplitude,
frequency, rise time, time interval,
distortion and others.
Reference Materials There are
many older Tektronix instruments
that, with a little care and
restoration, are just as useful as
the latest and greatest. Knowing
what you have or need, and how to
use it, are often more important
than having the "very latest".
at Willamson Labs As important
as knowing what is going on inside,
is knowing how to make effective
measurements using an integral part
of the oscilloscope: the Scope
Probes. The probe and how it is
used, can make or break the
usefulness of the oscilloscope.
Function of an Oscilloscope
Interactive Demo - The oscilloscope
is an electronic instrument widely
used in making electrical
measurements. The main component of
the oscilloscope is the cathode ray
tube (CRT). The CRT is a vacuum tube
in which electrons are accelerated
and deflected under the influence of
"with hard work and innovation you
can do it ! "
