The latter is a key technique for achieving a low distortion oscillator. Through the years, HP oscillators were used to design, produce and maintain telephones, stereos, radios and other audio equipment.

The Model A was HP ‘s first product. Dubbed the A to make it seem like the company had aaudio around for a jp, this instrument represented the first low-cost method of measuring audio frequencies.

In a letter, Dave described Hewlett’s audio oscillator as “the foundation on which Hewlett-Packard Company was able to grow into the largest manufacturer of electronic instruments in the world, the keystone that allowed four and one-half decades of major contributions to electronic measurement technology and equipment. Take this product for an interactive spin. The circuit diagram is shown in Hewlett’s patent. It was a low-distortion audio oscillator used for testing sound equipment.
