Sweep Function Generator 4040A

Product ID: Sweep Function Generator 4040A

20 MHz Sweep Function Generator

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 30MHz. 
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.
