TEST INSTRUMENT SAFETY
WARNING Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes be performed where exposed voltage is present. An electricalshock causing 10 milliamps of current to pass through the heart will stop most human heartbeats. Voltage as low as 35 volts dc or ac rms should be considered dangerous and hazardous since it can produce a lethal current under certain conditions. Higher voltages pose an even greater threat because such voltage can more easily produce a lethal current. Your normal work habits should include allaccepted practices to prevent contact with exposed high voltage, and to steer current away from your heart in case of accidental contact with a high voltage. You will significantly reduce the risk factor if you know and observe the following safety precautions: 1. Don't expose high voltage needlessly. Remove housings and covers only when necessary. Turn off equipment while making test connections inhigh-voltage circuits. Discharge high-voltage capacitors after removing power. 2. If possible, familiarize yourself with the equipment being tested and the location of its high voltage points. However, remember that high voltage may appear at unexpected points in defective equipment. 3. Use an insulated floor material or a large, insulated floor mat to stand on, and an insulated work surface onwhich to place equipment; and make certain such surfaces are not damp or wet. 4. Use the time proven "one hand in the pocket" technique while handling an instrument probe. Be particularly careful to avoid contacting a nearby metal object that could provide a good ground return path. 5. When testing ac powered equipment, remember that ac line voltage is usually present on some power input circuitssuch as the onoff switch, fuses, power transformer, etc. any time the equipment is connected to an ac outlet, even if the equipment is turned off.

INTRODUCTION
The heart of the function generator is aVCG (voltagecontrolled generator) that produces precision sine, square, or triangle waves over the 0.5Hz to 5MHz range. This encompasses subaudible, audio, ultrasonic, and RF applications. A continuously variable dc offset allows the output to be injected directly into circuits at the correct bias level. Variable symmetry of the output waveform converts the instrument to a pulse generator capable...
