Using
A Function Generator
A function generator is an instrument that generates signals for use in
electronic test situations.
-
A function generator
generates
signals. You may also find that another common name for the instrument
is signal generator.
-
The signals produced
by a function generator can have many waveshapes. You may find
-
Sinusoidal signals
-
Square wave signals
-
Triangle signals
-
Ramp signals
-
Pulses
-
Noise signals
-
User-defined signals.
-
The frequency of
the signals can be controlled.
-
The amplitude of
the signals can be controlled.
Not all of the signals above are found on every function generator, and
there are more specialized functions that can be performed. In general,
a generator that produces the first three signals may be called a signal
generator, and with more functions the generator may be called a function
generator. Where that line is drawn is not completely clear.
Using A Function Generator
There are three basic controls on a function generator. They are:
-
A control to set
frequency
-
A control to set
waveshape (sinusoid, triangle, etc.)
-
A control to set
amplitude
Turn the function generator ON and be sure that you can do the following:
-
Display the output
waveshape on an oscilloscope.
-
Set the frequency
to a value you want.
-
Set the amplitude
to a value you want.
-
Change the waveshape
to whatever waveshape you want.
