Re: Will I have a problem if my IQ data coming in is not in sync with 48000, 96000, etc?

Hi Jim,


Thanks for the expertise!??


I think I can get to 1.017253 the correct frequency if I use the standard 125 MHz Pico frequency.? It is very easy to change though.? Of course, it cannot be changed to an arbitrary frequency, but changing it can help a lot.? By changing to 86 MHz, I can get 0.9998139 correct.? There are some other frequencies that are almost as good as 86 MHz that are faster.? It sounds like adjusting a few points every so often works better in your experience.? Is that right?


Thanks & 73,


Rob

I have never had success with resampling I/Q data. The balance is degraded and images appear. How close to a multiple of 48 ksps can you get?
