    THD calculation & THD vs frequency graph smoothing

    Okay, thanks. THD+N just looks so strange due to lower noise floor in the newer version) Will there be a menu option to toggle between window modes?

    THD calculation & THD vs frequency graph smoothing

    Well, the question remains unanswered: how do I compare my new measurements with existing database? It's obvious that new window produce different results. I want my measurements to be consistent and comparable with others', which were done with previous versions...

    THD calculation & THD vs frequency graph smoothing

    Ah, so it happens automatically?

    THD calculation & THD vs frequency graph smoothing

    At this moment it uses new window system by default and I think you can't change it

    THD calculation & THD vs frequency graph smoothing

    The problem is: this is a file import, not a realtime measurement...

    THD calculation & THD vs frequency graph smoothing

    Oh, I've read that note, but was unsure, whether it gives that effect or not. Thanks! Precision aside, how can one compare older and newer results? You were absolutely correct about those graphs: it was a compander simulation test with distortion buried under the noise floor...

    THD calculation & THD vs frequency graph smoothing

    Hello! I've recently downloaded a new REW beta (5.40 beta 98 to be specific) and now I'm puzzled. It seems that new beta not only uses different algorithm to plot THD vs freq. data (graph seems less smoothed), but the entire calculation process has changed! These are 2 exact files of sweep...
