Has a couple minor probs, but it should be good enuf for a home shop.Since it's a thru hole kit I can prob add more pwr line decoupling (10nf for 25Mhz?) with a 10uF (SMD) local backup to lower it's impedance & and place an esr transorb on the inner side of the 49 ohm output resistor for ESD.
Just in case, make sure that what you buy, if coming from China, is not one of the small boards where the manufacturer failed to implement the correct output filter.
In the quest of a sweeping DDS generator myself I read several comments as above, maybe related to the 5932.
What stops me is that the 5930 comes as SMT only.
Anyway, once I find a way to calculated the reccomended eliptic filter I will give a try.
Notice the wave form looks bad near the maximum frequency.
The square wave has jitter because; there is a place to make a edge (positive or negative) every 25mhz. (40nS) If you want a 500khz square wave with edges every 1us things look good. If you want a edge every 1.001us things do not look so good. You will get edges at 1uS and 1.04uS with nothing in between. Looks like jitter.
