Thanks. If i get this right i can use the formula (√(Sample rate/FFT size)) this gives me a scaling factor to go from V to V/√Hz. There is no V/√Hz. Option in the All SPL tab and im trying to work around this.

Can i uses this formula to calculate the RMS noise? Do i have to apply window scaling factor? dose REW automatically apply "window scaling factor" if i uses V/√Hz?

Ok i understand I would highly appropriate this! Thanks for the tip! This might be related: analog.com/en/technical-articles/use-noise-spectral-density-to-evaluate-adcs-in-software-defined-systems.html kluedo.ub.uni-kl.de/frontdoor/deliver/index/docId/4293/file/exact_fft_measurements.pdf

Thanks. this is what i want. How can i capture this measurement? I don't want this. i was just noticing i can do this and was wondering why. Sorry, I try to do a Better job expressing my Questions. I want to Export this measurement: Here i can read of about 7-8µV√Hz @1khz independent of...

To Measure Noise Spectral Density √Hz? How else would i do this?

Thanks a lot for the replay! If i save the measurement from the RTA with the "Save Current button" it appears in the main window where i can view it in dBFS but this measurement is no longer independent of the FFT length? so can i only view it in the RTA window? Is there a fixed "correction...

Hello, First of all thanks a lot for this awesome software tool! How to make absolute "noise density" measurements of uncorrelated noise in REW? In the Jaaa "doku" i found. /kokkinizita.linuxaudio.org/papers/jaaa-pres If I change the FFT size of cause the noise floor changes How can i...
