INTRODUCTION
The B+K Precision Model 4011A Function Generator
is a versatile signal source which combines several
functions into one unit. 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. High stability assures
that the output frequency does not drift.
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 0.5Hz 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 of generating
rectangular waves or pulses, ramp or sawtooth waves, and
slewed sine waves.
In addition to the above features, an external signal may
be used to sweep the output frequency or control operating
frequency. This is useful in situations where an externally
controlled frequency is desirable.
