Another usefull 'option' might be to give the SNR of any signal you put the cursor on, so in that case the reference has to be the 'background noise'. 73, Rik ON7YD At 13:22 27/03/01 +0100, you wrote: >Alberto,I am not an expert here, but if I wanted to compare signals over a period of time, I would think it necessesary to establish a reference level say from a signal generator.This would include all the elements in the chain including the reciever.So if a ref. level is established in this way, clicking on this first and then on the unknown signal would determine the difference in db as you suggest. For what its worth! 73s Laurie. > >Attachment Converted: "C:\EUDORA\ATTACH\LF(TECH).htm" >
