Re: AD9361/4 IIP3 measurement

Thanks tlili!

 

Since the IIP3 provided in the spreadsheet is out of band IIP3, it looks like I will need to do the out of band IIP3 measurement as well. To do this, I still can't figure out how to generate the two tone signal. For example, rx frequency at 2400MHz with Fs of 30.72MHz. Where in the frequency band should I place the two tones? And see from the IIP3 measurement documentation, in Figure 1 Out-of-Band IIP3 Setup, what signal should I measure? There is no obvious IMD3 (which is the power difference between target signal and 3rd order product), can you tell me how to do the measurement?

 

Thanks!
