Hi, recently I made a comparison between various compressors of different companies to see what does this made to our signal.
The test was the following, I generated a signal of 1khz with pro tools signal generator at -10dB, so the settings for the compressors must not compress at all and the output should match -10dB again to see if any harmonics is added and at what level.
Note: Native Instruments controls were not as accurate, -10dB was not easy, if not impossible, to achieve so close approximations were use.

Nice work. But this data needs to be interpretated as well.

For referencing, a screenshot of the original tone spectrum is necessary to check if that is a "pure" tone or if it already has overtones. Also, the analyzer should be setup the same every time. The frequency range of some of the spectrums starts around 1 kHz where others show the full spectrum which could be misleading and makes it diffivult to compare the overtone structure against each other.

 

You are right, let me upload some new material.
