| Nov 29, 2013 at 17:05 | comment | added | The Photon | @Aug, at your linked page, I don't see which features you are calling "low frequency aliases" and which features you are calling "high frequency images". Also you say above your problems are caused by a combination of several things including "bad ground line" and "bad prototyping PCB design." You absolutely must fix these two problems and show us the results before we'll be able to distinguish whatever problems you have with aliasing. | |

| Nov 27, 2013 at 19:19 | comment | added | The Photon | I'm not sure I understand your question. What are you distinguishing between when you talk about "high frequency images" and "low frequency aliases"? Can you share the spectrum of your signal, showing what you mean by these two components? | |

| Nov 26, 2013 at 8:02 | comment | added | Aug | @ScottSeidman No, finally I found it was a combination of all : scope + low frequency aliases , inherent to "Real world DDS" ( the second link provided in the question ) + bad ground line passing from FPGA instead of the dedicated pins + bad prototyping PCB design +...... and possibly many many other things that come into the account in high frequencies ( event perhaps the Martians ! :) ) !! | |
