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.
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 to
explode.

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.

CONSTRUCTION
Introduction
● Turn off iron when not in use or reduce temperature setting when
using a soldering station.
The most important factor in assembling your FG-500K Function
Generator Kit is good soldering techniques. Using the proper soldering
iron is of prime importance. A small pencil type soldering iron of 25 watts
is recommended. The tip of the iron must be kept clean at all times
and well-tinned.
● Tips should be cleaned frequently to remove oxidation before it becomes
impossible to remove. Use Dry Tip Cleaner (Elenco® #SH-1025) or Tip
Cleaner (Elenco® #TTC1). If you use a sponge to clean your tip, then use
distilled water (tap water has impurities that accelerate corrosion).
Solder
Safety Procedures
For many years leaded solder was the most common type of solder
used by the electronics industry, but it is now being replaced by leadfree solder for health reasons. This kit contains lead-free solder, which
contains 99.3% tin, 0.7% copper, and has a rosin-flux core.
● Always wear safety glasses or safety goggles to
protect your eyes when working with tools or
soldering iron, and during all phases of testing.
● Be sure there is adequate ventilation when soldering.
Lead-free solder is different from lead solder: It has a higher melting
point than lead solder, so you need higher temperature for the solder to
flow properly. Recommended tip temperature is approximately 700OF;
higher temperatures improve solder flow but accelerate tip decay. An
increase in soldering time may be required to achieve good results.
Soldering iron tips wear out faster since lead-free solders are more
corrosive and the higher soldering temperatures accelerate corrosion,
so proper tip care is important. The solder joint finish will look slightly
duller with lead-free solders.
● Locate soldering iron in an area where you do not have to go around
it or reach over it. Keep it in a safe area away from the reach of
children.
● Do not hold solder in your mouth. Solder is a toxic substance.
Wash hands thoroughly after handling solder.
Assemble Components
In all of the following assembly steps, the components must be installed
on the top side of the PC board unless otherwise indicated. The top
legend shows where each component goes. The leads pass through the
corresponding holes in the board and are soldered on the foil side.
Use only rosin core solder.
Use these procedures to increase the life of your soldering iron tip when
using lead-free solder:
● Keep the iron tinned at all times.
● Use the correct tip size for best heat transfer. The conical tip is the
most commonly used.
DO NOT USE ACID CORE SOLDER!
What Good Soldering Looks Like
Types of Poor Soldering Connections
A good solder connection should be bright, shiny, smooth, and uniformly
flowed over all surfaces.
1. Solder all components from the
copper foil side only. Push the
soldering iron tip against both the
lead and the circuit board foil.
Soldering Iron
Component Lead
1. Insufficient heat - the solder will
not flow onto the lead as shown.
Foil
Soldering iron positioned
incorrectly.
Circuit Board
2. Apply a small amount of solder to
the iron tip. This allows the heat
to leave the iron and onto the foil.
Immediately apply solder to the
opposite side of the connection,
away from the iron. Allow the
heated component and the circuit
foil to melt the solder.
3. Allow the solder to flow around
the connection. Then, remove
the solder and the iron and let the
connection cool. The solder
should have flowed smoothly and
not lump around the wire lead.
Solder
Soldering Iron
2. Insufficient solder - let the
solder flow over the connection
until it is covered.
Use just enough solder to cover
the connection.

Rosin
3. Excessive solder - could make
connections that you did not
intend to between adjacent foil
areas or terminals.

4. Here is what a good solder
connection looks like.

4. Solder bridges - occur when
solder runs between circuit paths
and creates a short circuit. This is
usually caused by using too
much solder.
To correct this, simply drag your
soldering iron across the solder
bridge as shown.

Set the switch and pots as in Step 1. Connect the
oscilloscope to the sine/triangle wave output and
vary the AMPLITUDE pot. The sine wave amplitude
should vary from near zero to approximately 3V peak
to peak or greater.

FUNCTIONAL DESCRIPTION
The FG-500 is a function generator integrated circuit capable of producing high quality sine, triangle, and
square waves of high stability and accuracy. A picture of each waveform is shown below:
Sine Wave
Triangle Wave
THEORY OF OPERATION
Square Wave
FUNCTIONAL BLOCK DIAGRAM
The heart of the FG-500 Function Generator is the
XR-2206 monolithic function generator integrated
circuit. The XR-2206 is comprised of four main
functional blocks as shown in the functional block
diagram (Figure 1). They are:
AM Input
● A Voltage Controlled Oscillator (VCO)
Sine/Saw
Output
● An Analog Multiplier and Sine-shaper
Mult. Out
● Unity Gain Buffer Amplifier
● A set of current switches
V+
The VCO actually produces an output frequency
proportional to an input current, which is produced by
a resistor from the timing terminals to ground. The
current switches route one of the currents to the VCO
to produce an output frequency. Which timing pin
current is used, is controlled by the FSK input (pin 9).
In the FG-500, the FSK input is left open, thus only
the resistor on pin 7 is used. The frequency is
determined by this formula:
Timing
Capacitor
Timing
Resistor
fo = 1/RC Hz
where fo is the frequency in Hertz
R is the resistance at pin 7 in Ohms
C is the capacitance across pin 5 and 6 in Farads
Note that frequency is inversely proportional to the
value of RC. That is, the higher the value of RC, the
smaller the frequency.
The resistance between pins 13 and 14 determine the
shape of the output wave on pin 2. No resistor
produces a triangle wave. A 200W resistor produces a
sine wave.

FREQUENCY MULTIPLIER
The output marked SINE/TRIANGLE provides the
sine and triangle waveforms. The output marked
SQUARE WAVE provides the square wave. The
output marked GND provides the ground for all
output waveforms.
The multiplier is a variable control allowing frequency
settings between fixed ranges. The ranges are as

The Amplitude Control provides amplitude
adjustment from near 0 to 3V or greater for both sine
