THD+N unweighted & A weighted and averaging with sweep measurement

[ttako]

Dear All,

I am really sorry if this was already covered, I did not find much info on it.
I am quite new to REW. I use Cosmos ADC and SMSL SU-9pro for measurements. (I did use an AP2322 for this purposes till now)
I would like to measure THD+N A-weighted and Unweighted as well with sweep measurement.
I know it is possible with stepped sine, but it is quite slow.
Also I am wondering, if averagign could be possible also with sweep measurement?

Thanks,

Tamas

If you vector average a set of measurements REW will also average their distortion results. Sweep measurements cannot produce a THD+N result.
