IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads) or μF (microfarads). Most
capacitors will have their actual value printed on them. Some capacitors may have their value printed in the following manner.
Electrolytic capacitors have a positive and a
negative electrode. The negative lead is
indicated on the packaging by a stripe with
minus signs and possibly arrowheads. Also, the
negative lead of a radial electrolytic is shorter
than the positive one.
Warning:
If the capacitor is connected
with incorrect polarity, it may
heat up and either leak, or
cause
the
capacitor
explode.
INTRODUCTION
Assembly of your FG-500 Function Generator will
prove to be an exciting project and give much
satisfication and personal achievement. The FG-500
contains a complete function generator capable of
producing sine, square and triangle wave forms. The
frequency of this generator can be contiuously varied
from 1Hz to 1MHz in 6 steps. A fine frequency control
SPECIFICATIONS
OUTPUT:

The amplitude of the wave forms are adjustable from
0 to 3Vpp. This complete function generator system
is suitable for experimentation and applications by
the student. The entire function generator is
comprised of a single XR-2206 monolithic IC and a
limited number of passive circuit components.
SQUARE WAVE:
• Amplitude: 8V (no load)
• Rise time: Less than 50ns (at 1kHz)
• Fall time: Less than 30ns (at 1kHz)
• Symmetry: Less than 5% (at 1kHz)
TRIANGLE WAVE:
• Amplitude: 0 - 3Vpp
• Linearity: Less than 1% (up to 100kHz)
POWER REQUIREMENTS:
• Standard 9V battery
