6. APPLICATION NOTE
This section describes the application of the Function Generators in
details as well as a brief description relating to the block diagram. Only
for the essential application method.
(A) Trouble-shooting by using signal-tracing method.
This method is similar to signal replacing way. The signal of model
will be fixedly sent to input terminal. Observing its signal wave on the
oscilloscope from front stage to rear stage orderly until appear a
signal with normal input but with abnormal output.
(B)
Use as bias source and signal source circuit.
Utilize the Figure 4 of connecting type, which can provide bias of a
transistor and signal input. The output waveform can be observed
from oscilloscope. Adjust to the best condition with output max.
amplitude and no distortion. Adjust DC OFFSET to see the different
effect of different bias condition.
(C) Amplifier over-load characteristics
The Sine wave input will be different from output the overload point.
Using Triangle wave will easily observe the display of oscilloscope.
It can decide the linear range of output waveform. And the largest no-
distortion output amplitude.
