AVT5124 A

DDS generators are increasingly appearing in professional equipment offers, more and more often they are built by amateur electronics themselves. The presented device was designed based on the modern integrated circuit from Analog Devices with the DDS synthesis. Its structure has a 10-bit A / D converter. With this resolution, sinusoidal and triangular waveforms are generated. All information necessary to operate the device is presented on the graphic display and the introduction of appropriate extensions is possible using a 16-button keypad. The input mode is selected by the user as required.

The device is especially recommended as a workshop device, in a service and construction workshop
