Hi, I am having an issue exporting THD data. The text file at low frequencies does not seem to agree with the data I see in the curves within REW. See attached for screen shots of the curve in REW and the text file. The curve shows distortion in the 30-70% range below 200 Hz, while the text file shows completely different numbers peaking at 109%. What am I doing wrong?

Thanks

Never mind, I figured it out. The"Limit Normalization to 30 dB below peak" was checked, and it looks like this impacts the graph but not the exported data. When I unchecked this, all agreed.
