b&K Precision 4011A function generator

Description

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 precise setting 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 sub audible, 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.
