So Jude, so why you are so obsessed with measurement e-peening? For example, I cite this from your shitty forum: https://www.head-fi.org/threads/sen...ost-for-summary.795365/page-201#post-13981800 You want to know why your noise floor is 45db lower? It's because of this thing called FFT Process Gain. This was discussed years ago on www.changstar.com here: http://www.changstar.com/www.changstar.com/index.php/topic,2796.0.html It has to do with FFT window size or as your noobishly call it, FFT points. At the end of the day, none of this shit matters. It's all academic and shit 140db down doesn't seem to correlate to anything that I can hear. 140db is like 1/10 million in terms of voltage ratio. Finally, you also took my "10db lower comment" totally out of context, which was with the use of a balanced voltage divider probe within the scope of my own measurements, not in comparison to your lower noise AP with 16M FFT points. So Jude, just shut the fuck up. You don't know WTF you are talking about. Stop embarassing yourself. You're not technical. You don't understand the math behind it. You are a measurement noob. Heck, I'm a measurement noob too - I'm still learning every day.
