DDS

Direct digital synthesis (DDS) is a method employed by frequency synthesizers used for creating arbitrary waveforms from a single, fixed-frequency reference clock. DDS is used in applications such as signal generation, local oscillators in communication systems, function generators, mixers, modulators, sound synthesizers and as part of a digital phase-locked loop.

RF Signal Generator AD9912 DDS 500MHz Arduino Shield

“The way to create Low Noise Oscillatror Sinus Wave up 500 MHz, CMOS up 150MHZ, HSTL 1GHz based on DDS from Analog Devices - AD9912 Why did we choose to build a Direct Digital Synthesizer (DDS) based on the AD9912 by …

How to Use Arduino DDS Frequency Signal Generator AD9850

“In this Tutorial we will learn how to make a Frequency Signal Generator using a AD9850 module and Arduino. Watch the Video! Note: I managed to get frequency up to +50MHz but the signal quality gets worse with the higher …

HF Antenna Analyser With Arduino and DDS Module

“In this Instructable I’ll show you how I built a low-cost antenna analyser which can measure an antenna and display its VSWR over any or all of the HF frequency bands. It will find the minimum VSWR and corresponding …

Build your own cheap antenna analyser

“Ham radio is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, etc. Developing a ham radio project may requires using an antenna analyser, a device that is used for measuring input frequency …
