The BK 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.
