DDSH Direct Digital Synthesizers with USB control & Fast sweeping
Description
This specific Direct Digital Synthesizers DDSH is an improved version of the DDS and it offers new features. Via the provided software, the user can select not only the frequency control (Analog 0-5V or Digital 31 bits or USB) but also the amplitude control (analog 0-5V or digital 12 bits or USB). The DDSH should be coupled with an amplifier in order to deliver the required RF power.
