Hello
I've been using REW for a while now and noticed a few things I wanted to make sure I got right:
1. When we are analyzing a frequency response, what we see in the “SPL & Phase” tab is the same as the “Fundamental” amplitude and phase in the “Distortion” tab.
2. The software does not provide any information about the distortion phase (second harmonic phase, third harmonic phase, etc.).
3. Equalization is achieved by inverting the first harmonic frequency response (Fundamental) and multiplying it by input. Thus EQ also is called preEQ.
4. In REW, we don't have anything with the concept of second harmonic equalization.
Thanks
