Spectrometer doesn´t work as before


In WLP 9.5 spectrometer doesn´t work, if FFT analysis block size is over 32768. I need 262144 for high accuracy measurements in low register notes.
In WL 9.1. it worked well, but not any more. Is this a bug or am I doing something wrong?


This is a bug that is corrected in upcoming 9.5.20 version.
This being said, the big block you mention can be very CPU consuming, especially if the overlap factor is high.
Be aware of this.
