Hi,
I use REW almost exclusively for electronic measurements.
I design mainly dynamics processing gear, multiband compressors and dynamic EQ's.
A feature I haven't seen in REW is amplitude sweeps.
Several alternative softwares offer amplitude sweeps for THD vs. level, but I'm really interested in Vout vs. Vin, for evaluating compression slopes.

The stepped level test produces a linearity plot that shows output vs input at the test frequency.

Thank you for showing me.
I find it's somewhat tedious to achieve what I want, since the graph cannot be resized to show only the fundamental, so I have to change screen to the SPL & Phase. But I would like to superpose several results and I can't get the All SPL to do that.

Some form of overlay plot for stepped level measurements is on the todo list.

Thank you!
