INTRODUCTION - ANALOG SECTION

The Analog Section of your trainer contains a complete function generator capable of producing sine, square,
and triangle waveforms. The frequency of this generator can be continuously varied from 1 hertz to over
100,000 hertz in five steps: 10, 100, 1k, 10k, and 100k. A fine frequency control makes selection of any
frequency in between easy. The amplitude of the waveforms are adjustable from 0-15Vpp. A waveform of
function generator capable of producing sine, square and triangle waveform outputs has a wide range of
applications in electrical measurements and laboratory instrumentation. 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.

USERS DESCRIPTION OF FRONT PANEL CONTROLS

1. WAVEFORM - Selects square, triangle or sine waveform at the FREQ output.

2. COURSE FREQUENCY - Selects five ranges of frequencies 10, 100, 1k, 10k and 100k hertz.

3. FINE FREQUENCY - Allows easy selection of desired frequency according to the frequency range.

4. AMPLITUDE - Controls the amplitude of the FREQ output signal from 0-15Vpp.

5. DC OFFSET - Controls the DC level of the FREQ output signal. The DC level may be varied 10 volts from

zero level.

6. CLK - A 4-pin output block for function generator’s square wave. The amplitude of the signal is 5Vpp and

frequency is dependent on WAVEFORM selection.

7. FREQ - A 4-pin output block for function generator’s signals, output is dependent on WAVEFORM selection

and frequency is set by COURSE FREQ control. The amplitude of the output is variable from 0-15Vpp.
