TEST INSTRUMENT SAFETY

WARNING

Normal use of test equipment exposes you to a certain amount of danger from electrical shock because testing must sometimes b e
performed where exposed voltage is present. An electrical shock 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 all accepted 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 in high-voltage circuits. Discharge high-voltage capacitors after removing power.

2. If possible, familiarize yourself with the equipment being tested and the location of its hi gh 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 on which 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 circuits such as the on-

off switch, fuses, power transformer, etc. any time the equipment is connected to an ac outlet, even if the equipment is turned off.

INTRODUCTION

The B+K Precision Model 4017A Sweep/Function

Generator is a versatile signal source which combines several
functions into one unit - waveform generation, pulse generation
(through variable symmetry), and frequency sweep. Additionally,
the instrument provides the added convenience of a built-in
frequency counter. This permits more accurate determination of
output frequency than is possible with a simple calibrated dial.
Coarse and fine tuning controls permit precision settability of the
output frequency.

With this versatility, the unit has a vast number of applications
in both analog and digital electronics in the engineering,
manufacturing, servicing, educational, and hobbyist fields.

The heart of the function generator is a VCG (voltage­controlled generator) that produces precision sine, square, or

triangle waves over the 0.1Hz to 10MHz 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.

The sweep generator offers linear or log sweep with variable

sweep rate and adjustable sweep time.

Variable symmetry of the output waveform converts the
instrument to a pulse generator capable of generating rectangular
waves or pulses, ramp or sawtooth waves, and slewed sine waves.

In addition to the above features, an external voltage may be
used to control operating frequency. This is useful in situations
where an externally controlled frequency is desirable.
