Inclusion of the CEA 2034-A threshold curve mask

JOHN-rew - I'm having trouble generating stepped sine (64k FFT, 24 ppo) in REW. I would appreciate your help! (did I not understand that the REW swep is already stepped sine?).
I have a suggestion if it is suitable: in the same way that you incorporated the REW into the house curve, why not include the CEA 2034A distortion threshold curve as shown below? this would help a lot to interpret if the distortions are significant in the respective frequency bands in IMHO!
Thank you for your usual attention!

John-REW Sorry for the previous request! I reinstalled REW and the stepped sine worked in the RTA window! lf a problem with my pc. My suggestion to include the CEA 2430-A distortion mask is valid!

Those thresholds are for use with the CEA-2010 burst signal for max SPL measurements, they aren't really an indicator of significance but a limit on the distortion beyond which it is no longer permitted to claim the overall level as a valid maximum output. There is an option in the RTA appearance settings to use either CEA-2010 or CEA-2034 distortion thresholds with the burst signal.
