Thanks for the explanations, even if I didn’t post any question I still not used my interface for measurements.Afterwards, you can build your measurement signal chain like this: Laptop HP Out->[DUT]->Focusrite Line in->back to Laptop, and the frequency and phase response of all but the DUT ("Device under Test") will be corrected, so that only the DUT response remains.
As soon as you change the signal chain WRT I/O, the cal file becomes invalid.
Changing the I/O will require a recalibration, if you want to minimize the impact of your measurement equipment on the final result.
In the case where I want to measure my monitors response on my room, should I calibrate the Focusrite or is enough approximation to suppose it is relatively linear?
Or since my interface has 2 line inputs can REW consider a signal path line out 2 => line in 2 as a reference when testing line out 1 => speakers => room response => mic? => line in 1?
In this case supposing the mic is calibrated
