ADS6144：What is the number of FFT points in the specs sheet's typical characteristics?

Nelson Hall

TI,

To help me verify my design, how many points were taken to produce the following FFT shown in the spec sheet? Is this only an FFT or was a PSD calculated? Any help is apprecitated.

Here is the FFT in question:

Hi,

In most cases 32K samples were taken for the FFT for the data sheet plots, and in this case I checked with the design team and indeed it was 32K samples this time as well. This is just the FFT plot, that is - the amplitude portion of the result from the FFT function.
