How perform Zoom FFT with no real time daq?

[Eng P&D]

Hello,

I'm having some troubles about perform Zoom FFT with no real time data aquisition.
I think the problem is in the number of blocks of time signal that I have to send to Zoom FFT.
When using FFT baseband it works well inside loop.
May it depends on the start frequency value and the number of lines.
If someone could help me... Thanks

Hi Eng P&D,

I'm sorry, but I don't understand the question.  I would like to know exactly what you are doing.

What type of signals are you sending in?
Where did that data come from?
What datatypes are the signals stored in?
What results do not look correct?
What Zoom FFT VI are you using?  We have Zoom FFTs built-in to some of our DSA hardware, and we also have Zoom FFTs in the Spectral Measurements Toolkit.

Would it be possible to send your code?

Thanks,
mike
