No, it's fine. I didn't ask you to make an exception and neither do I want you to.So you want me to put a filter on the output of a class of DACs to make them measure better but not do it for others which don't emit too much ultrasonic noise?
If there is excess ultrasonic noise, then the device may fail regulatory testing as well.
So no, I can't make a special case for testing this device. Plenty of other devices generate out of band noise which impact measurements. In this case, that impact is nothing compared to 0 dBFS saturation for which we still don't have an answer. I was hoping by now we would have an investigation of that and hopefully with a firmware update, would be behind us. Instead, we seemed to be wrapped around axil on minutia and theory with no consequence at all.
I'm just trying to understand which parts of your results show the DUT and which show the lab equipment and its limits.
