Focusrite Scarlett Solo or 2i2?

[Incognitoz]

Hello, I am interested in using the REW software to measure loudspeakers drivers, acoustic and electrical measurements (impedance) and Thiele/Small calculations.
My question is if a Focusrite Scarlett SOLO can do the job or I need buy Focusrite Scarlett 2i2 soundcard to do the relevant measurements?

Thank you.

You would need the 2i2 for the impedance measurements.

Dear John, Thank you very much for the quick answer.
Another question please, can a cheaper interface like Beringer umc202hd can affect the level of measurement accuracy for my needs?

Thanks

Distortion of the UMC202HD is a little high, but it could be used for your purposes. There is some discussion of using it for measurement here.
