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.
