Good morning. I have a question about the data displayed by the RTA "Show distortion" window. Using the generator I produced a 1Khz and -80 dbV signal which I sent to RTA.
The "Show distotion" window, the cursor and the value displayed in RTA practically all coincide at -80dbV.
Then I generated a 1kHZ but -120dbV signal. The cursor and the value displayed in RTA practically coincide (-119.7dbV) but the "Show distortion" window provides a completely different value (-111.16 dbV).
Where am I wrong? Thank you all
