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.
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-600 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.
Assemble Surface Mount Components The most important factor in assembling your FG-600 Function Generator Kit is good soldering techniques. Using the proper soldering iron is of prime importance. A small pencil type iron of 10-15 watts is recommended. A sharply pointed tip is essential when soldering surface mount components. The tip of the iron should be kept clean and well tinned at all times. Many areas on the printed circuit board are close together and care must be given not to form solder shorts.
ASSEMBLE COMPONENTS TO THE PC BOARD Care must be given to identifying the proper components and in good soldering habits. Refer to the soldering tips section in this manual before you begin installing the components. Place a check mark in the box after each step is complete. R1 - 620Ω 5% 1/8W Res.

INSTALL COMPONENTS TO FRONT PANEL (continued) r Install the colored binding posts to the panel as shown in Figure I. Use the hardware shown in the figure. Make sure that the small nuts are tight. Nuts Lockwashers Small nut Binding post Black Figure I Yellow Yellow WIRING (See Figure J) r Solder the wire from hole J1 on the PC board to the first yellow binding post as shown. r Solder the wire from hole J2 on the PC board to the second yellow binding post as shown.
FINAL ASSEMBLY r Fit the PC board assembly into the top case, making sure that all switches and pots come through the holes in the panel as shown in Figure K. 7mm Hex pot nuts 9mm Hex switch nut r Place the washers onto their locations as shown in Figure K, being careful to check the sizes. Then, tighten the hex nuts onto the potentiometers and rotary switch, noting their size as shown in Figure K.
FINAL ASSEMBLY (continued) r Remove the backing from each rubber foot and place them in the locations shown in Figure M. r Turn the shafts on the two potentiometers and rotary switch fully counter-clockwise. Push the three knobs onto the shafts so that the line on the knobs are on the points shown in Figure N. r Assemble the top and bottom case sections and fasten with four 2.8 x 8mm self-tapping screws as shown in Figure M. Make sure the slots on the side line up with one another. 2.
TESTING THE FG-600 FUNCTION GENERATOR The unit may be tested by following the 4 steps listed below. Should any of these tests fail, refer to the Troubleshooting Guide below. 1) SET THE SWITCHES AND POTS AS FOLLOWS: On/Off Range Frequency Amplitude Sine/Triangle 3) FREQUENCY CONTROLS 6 range settings, vary the FREQUENCY pot from max to min and check that the frequency varies according to Table 1 on page 13.
FUNCTIONAL DESCRIPTION The FG-600 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 Square Wave THEORY OF OPERATION The heart of the FG-600 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).
CONTROLS RANGE SWITCHES Six ranges of frequency are provided by the range switch as shown in Table 1. POSITION 1 2 3 4 5 6 TYPICAL FREQUENCY RANGE 1Hz - 15Hz 10Hz - 150Hz 100Hz - 1.5kHz 1kHz - 15kHz 10kHz - 150kHz 100kHz - 1MHz Table 1 SINE/TRIANGLE SWITCH ON/OFF SWITCH This SINE/TRIANGLE Switch selects the waveform, sine wave or triangle wave, sent to the SINE/TRIANGLE output terminal. The ON/OFF Switch turns the power to the FG-600 on or off.
