The thread is about finding low-emission products (well below relevant limits) to act as 'support devices' , aka 'auxiliary equipment'. The low emissions are required in order not to significantly affect the measurements of the emissions of the equipment under test. With best wishes DESIGN IT IN!

I should have mentioned that, in this case, we (Bose Corp.) are the test lab and it's our equipment we're testing. We just came out with a couple of new audio-for-video devices that route HDMI through to pick out the 5.1 surround. Had a heck of a time finding good sources and sinks. Not sure there are very many test reports to be looked at since TVs are verification only device. I suppose that more might be found if they incorporate non-modular Wi-Fi or RF remotes..

It is ok to post recommendations on devices that are good for testing to this list. As the list is archived one can always search the archives for such things. I have used several approaches to finding good support devices. I have like others looked at FCC test reports. For the most part it was after getting recommendations to make sure it was a good choice. I look to make sure it was tested properly and had 6 dB of margin. That allows for production variations. I have on rare occasions looked for good support devices on the FCC website. I have also contacted compliance engineers at the company of interest to see what they recommend. In one case they told me not to use theirs. Not everyone supplies all support devices needed for testing. So the test labs do have support devices. Therefore you can ask your test lab as well, as they might have favorite support devices.
