I Don't think so. The Ethernet port has different properties (and problems), clock speeds etc. Same for the video. At a minimum I would think you are going to have 1 USB, 1 Video, and 1 Ethernet line. Then there is the clause which says keep adding cables for similar type devices until you get less than a 2 dB increase in emissions. Then, if the last cable hasn't exceeded the limits you can remove it. Adding and removing similar devices can work for or against you depending on whether the emissions add coherently or incoherently. I don't have immediate access to the standards so I won't quote the paragraph number - but unless that has been withdrawn I suspect somebody else can provided it. A contentious little paragraph and it can be expensive to determine this number. Gary

My EUT's are mostly USB devices, so I guess my EUT (a serial USB device) and a parallel printer would satisfy the minimum system configuration requirements, using a desktop computer. The laptop I have only has 2 USB, 1 Video, and 1 Ethernet port. Would I be able to satisfy the ANSI requirements by terminating 2 USB ports? Thanks, Tim Pierce
