Viewing FFT Data On the Live Session Log Tab
The Session Log tab is the same in FFT mode and SLM mode. For details, see 4.1.4
Understanding the Session Log Tab on page 45.
You can open and view saved FFT and Tonality data files on the 831C just as you would any
other type of file. Please note that for ISO/PAS 20065 measurements, no tonality data is
stored in the saved file. Instead, open the file in G4 where tonality information is calculated
for display each time the file is opened.
For specifics on viewing data files on the 831C, see 8.2 Using the File Manager on page 75.
For information about viewing FFT files in G4, see Module 9 of the G4
