BASIC OSCILLOSCOPE - OD 1402
INTRODUCTION
Electronically speaking, an oscilloscope is a device that makes the
invisible become visible. The invisible things we are interested
in seeing are the galaxy of different electronic signals present in
electronic circuitry. Connect the oscilloscope to any signal
circuit and you can follow the progress of the ever­growing signal
as it weaves its way from the input to the output terminals. The
luminous trace on the oscilloscope's screen shows you the signal's
every up, down, and twist. As you move the scope's probe from
stage to stage, you can view each stage's effect on the signal.
What can you do with an oscilloscope? Because the instrument is so
versatile, it's hard to find a point to begin talking about it. It
can be used to design circuitry, adjust variable component values,
and calibrate circuitry. It can also be used to troubleshoot
faulty circuitry when you know the correct waveform at each point
in the circuit. You just move the probe from stage to stage until
you find an out­of­shape waveform. You can also measure voltages
of alternating and direct currents and determine the frequency of
the cycles.
You get the idea. Throughout this subcourse, you will use the
oscilloscope to view various waveforms. You will also learn how to
determine the voltage and frequency of these waveforms. All of
this information should help the tank turret repairer become
comfortable with using the oscilloscope as a tool of his trade.
