Hello Jim, We hook up to the test labs internet infrastructure and stream data back and forth to our STBs. This test methodology has all the downsides that James has as upsides on his test method - with one exception. It's easy to justify. After all how can you argue with exercising the port as intended.?
Our external equipment has included switches/routers/PCs/other STBs in various flavors and (on the whole) its been OK. One does have to be judicious to pick trusted sources for the ubiquitous electronics though!! On a side note: I have always held the belief that a simple ping test will result in the full emissions profile. (And based on my experience I have no reason to change my mind!) I started that way and ran into the justification issues as alluded to earlier. Now - our boxes have at the most two ENet ports. The mind boggles at the logistics of testing a large set of I/O.!!

I am curious what means people are using to exercise Ethernet telecom ports when testing for conducted emissions according to CISPR 22 and conducted immunity according to CISPR 24? Do you use an external piece of equipment (AE) to send Ethernet traffic? If so, what do you use and do you like it? My particular interest is 1000BaseT (gigabit Ethernet), but the question is more general. Thanks in advance, Jim __________________________ James L.
