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 (voltage-
controlled 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.
