Hi, is it possible to add RTA THD correction in some way for external notch filter when measuring amplifier ? (based on notch H1,H2, H3 attenuation), thanks. Leslie

external generator (victor1k) at -5.5dBFS, they are pretty close

I made an experiment, crosslinked the two systems. OUT:ARTA, IN:REW OUT:REW,IN:ARTA Can you recognize something from these two graphs ?

The system (PC,OS,SOUND CARD,DRIVER) is the same. I just checked the generator output level with DMM, in both cases (ARTA,REW) show 1.179Vrms. "Full scale sine rms is 0 dBFS" is checked. In other system (WIN10, X-Fi USB) I also observed the same, REW measured ca the half THD.

Hi all , for years I used ARTA for distortion measurements. REW looks better, but when I compare RTA results, REW measures lower distortion level than ARTA (the harmonics are different also). Which system is more accurate ? What did I do wrong ? OS WIN7 64bit ESI JULI PCI LOOPBACK DRIVER...
