AD9850 40MHz DDS Function Generator Module

What we are looking for is the absence of short-term instabilities that would show up as easily visible wiggles in this line. This is more expensive but the modules are evidently of a higher quality. Where To Buy Nooelec. This is fine, not a problem.

Turn the potentiometer anti-clockwise “left” carefully, just a little at a time! Email to a Friend. Some kit builders have noted poor output on 10m, which has been resolved by very very slight adjustment of the comparator potentiometer.

Only registered customers who has bought this product can write reviews. The adjustment is almost correct here, but still slightly too anti-clockwise.


Call us toll free: Powered by the ubiquitous AD, so it will be easy to find code you will be able to adapt to your own project. In practice, seconds is sufficient to show any instabilities. Note that for these tests, the U3 PA is actually disconnected.

Note that it is Ok to ignore ringing on the edges, this is not related to the potentiometer setting. This is how the ‘scope trace looks when the potentiometer is turned all the way clockwise to its limiting position. The audio output of the receiver is fed into a laptop PC via a Logitech USB headset whose headset has been cut off and replaced by sockets, so that the USB audio ADC can be used to feed good quality audio into the laptop.

The adjustment is quite sensitive, the tiniest movement of the potentiometer affects the output waveform, and for the majority of the potentiometer’s travel, there is no waveform output at all.


The duty can be adjust by a adjustable resistor – which change the adjust voltage level of the comparer. Write Your Own Review Only registered users can write reviews.

Upon switch on of a new AD module of course, there is some warm-up drift of the MHz crystal reference oscillator, which shows as drift of the ARGO line. It will be appreciated if you can help us improve the documents by correcting the errors, adding more demo codes or tutorials. JavaScript seems to be disabled in your browser.

Frequency stability test To test the frequency stability, a simple 30m band direct conversion receiver is used, powered from a well-regulated linear power supply.
