INTRODUCTION
Assembly of your FG-600 Function Generator will prove to be an exciting project and give much satisfication
and personal achievement. The FG-600 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.
The FG-600 uses surface mounted components. By building this kit, you will obtain an interesting electronic
device and also gain valuable experience in surface mount technology.

PARTS VERIFICATION
Before beginning the assembly process, familiarize yourself with the components and this instruction book.
Verify that all parts are present. This is best done by checking off each item against the parts list.
Care must be taken when handling the chip resistors and capacitors.
They are very small and are easily lost. Chip resistors are marked
with their component value. The first 2 digits are the first 2 digits of
the resistance in ohms. The last digit gives the number of zeros
following the first 2 digits. The resistor shown at right is therefore
3900
Ω
.
The values of the chip capacitors are not marked on the component.
The chip capacitor C6 (820pF) is in the bag with the chip resistors,
the chip capacitor C5 (.01
µ
F) is in the bag with the lytic capacitors
and the chip capacitor C4 (.1
µ
F) is in the bag with the IC. To avoid
mixing these parts up, they should not be taken out of their packages
until just before they are soldered to the PC board.
