As usual in debates, the conclusion was yours, not mine, you would have the responsibility of killing the guy.
So you stated an irrelevant fact with respect to Entreq?
And sorry, IMHO the papers help interested people understanding the real problems in assessing the operation (or no operation, surely) of the device, as they show RFI problems that can exist in real devices.
Again, that is not what the papers are about. Let me quote you the first line the Intersil App note you posted:
"The proliferation of
wireless transceivers in portable
applications has created a need for increased attention to
an electronic circuits' ability to operate
in the vicinity of
high frequency radio transmitters. "
The bolded parts should make it clear that this was an irrelevant paper to post. But I will expand to make sure.
Intersil makes Bluetooth silicon and one of the primary applications of Bluetooth is for transmitting audio. They are trying to raise awareness for designers that when you put a 2.4 Gigahertz Bluetooth transmitter right next to an audio device in a small portable device like a smartphone, Bluetooth speaker, etc., that you have to be careful as one can bleed into the other. They build a test fixture that
injects up to 6 Ghz signal into the audio gear (second harmonic of 2.4 Gigahertz is 4.8 Ghz so you need to measure at least up to that point), and identify which circuit components can be susceptible to receiving and demodulating Bluetooth radio.
There is no applicability whatsoever to Entreq in any of this. You don't have a Bluetooth transmitter sitting inside your pre-amplifier and your designer, especially in high-end equipment, has made sure that radio frequencies don't bleed into their circuits. And even if you did have any of these issues, the last thing in the world you want to do is erecting an antenna in the form of a long wire from your equipment to an unterminated load like Entreq.
Your conclusion that audio equipment then has RFI and that it needs to be tested to 6 Ghz based on this paper has no merit at all. It is just a technique of throwing out technical stuff at people, hoping they don't read or understanding them and scoring a point. Please don't do that in this forum. It wastes time and energy to go chase this stuff.
