RTA "Turn off Get fundamental from generator"

[dch53]

Hi.

Just getting back into REW after a few months. I updated to the latest version.

When I run RTA, the distortion window includes the red text "Turn off Get fundamental from generator".

Can someone tell me what that's all about please?

I've looked around for somewhere to turn-off "Get fundamental from generator" but I can't find such a setting.

Thanks and regards, Dave.

The setting is here:

The message is shown because there is a difference (although in your case a very small one) between the replay and capture clocks, so the fundamental frequency should be determined from the input rather than using the generator figure.
