IDENTIFYING CAPACITOR VALUES
Capacitors will be identified by their capacitance value in pF (picofarads), nF (nanofarads) or mF (microfarads).
Most capacitors will have their actual value printed on them. Some capacitors may have their value printed in the
following manner.

The above value is 10 x 1,000 = 10,000pF or .01mF
The letter K indicates a tolerance of +10%

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 makes selection of any frequency in between easy. 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.
