BK Precision 4040A Sweep Function Generator, 20 MHz

The B+K Precision Model 4040A 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 stability of the output frequency. The internal frequency counter can also be used to measure external frequencies. The five-digit frequency counter displays the generator output frequency or external signals from 5 to 30 MHz.
