I'm not clear exactly how REW handles the calculation of the noise floor as it relates to frequency response and the waterfall plot. Is the measured noise floor taken into account in the FR/waterfall plot? Or is this left to the interpretation of the user?
My most recent measurements suggest a FR peak and some ringing at 60hz, and the distortion tab suggests that this may be a function of something going on in the noise floor. Perhaps the 60hz mains frequency here in the states. When I ran a RTA analysis, the same 60hz peak was prominent and steady.
Based on the attached plots, is this a reasonable interpretation?
Thanks.
