REW was already amazing when first released and somehow it keeps getting better and better. Thank you John!
Love the "plot harmonics at the harmonic frequency" option. Some recent graphs using it were enlightening even though the data is no different, just displayed differently.
I starting conducting some tests using a looped back connection. The generator is the source of a dual sine wave signal, to mimic 2nd harmonic distortion. Below is the RTA result.12KHz H2 is -11dB wrt the 6KHz fundamental. Noise, H3 and beyond are in the weeds. I expect to see a THD+N of 28ish% but is shows 0.20%. "get fundamental from generator" is not checked. Looks like REW might be thinking I'm doing something else and/or my setup is incorrect?
