This technology makes it possible to provide programmable clock and sinewave generators that are phase continuous, phase synchronous, phase aligned and/or frequency agile at low cost to the purchaser. Some years ago I became interested in DDS after reading a document A basic tutorial on Direct Digital Synthesis (DDS). WSPR Application WSPR “ W eak S ignal P ropagation R eporter” pronounced Whisper is a system which reports the propagation of very weak radio signals over the world. use on manual analyzers to find the sign of X. Restoring last configuration after power up. org Radio amateurs and RF engineers in general will welcome this design. Connecting the DDS Module to the Raspberry Pi to make a simple RF Signal Generator The DDS module used to generate the RF signal for the Raspberry Pi Wobbulator is based on the AD9850 frequency synthesizer chip and is available from a number of suppliers on eBay. Tired of using your PC or mobile phone as a signal generator? It's time to upgrade to a standalone one by making it yourself. DDS frequency synthesizer as used in an arbitrary function generator, AFG. This is a 0~55MHz DDS Signal Generator. Adopts DDS direct digital synthesis technology, can generate precise, stable output signals with higher distortion. RD JDS6600 25MHz 2-Channel DDS AW Function Signal Generator « on: June 14, 2017, 08:47:46 am » I was going to buy a cheap Feeltech, but some have reported that its lack of proper grounding is allowing voltages of around 90 volts at 1 milliamp to run through the probes. 20MHz function generator. 7, and also set your marker oscillator to 10. Features: This is a 0~55MHz DDS Signal Generator. This is a circuit designed to boost the output of a DDS signal generator or VFO to the level where it could be a QRP transmitter or could be used to drive a boatanchor type tube transmitter.
