| Re: RTA settings question
It's telling you that it's not an accurate true RTA display below that frequency indicated. It has to do with the FFT math. It is still an accurate level with respect to the pink noise used and the level received from the microphone, but it can't be called a true RTA representation below that frequency. Be sure to use periodic pink noise and the Hann windowing with the RTA.
