Re: [PSES] What means do you use to exercise Ethernet telecom ports?

[Doug Smith]

Hi Jim, Just be careful with the exercising equipment you use. I have seen a lot of Ethernet equipment that did not have very good balance and potentially cause a failure of either emissions or immunity unless you isolate it from the test electrically. For an example of such equipment take a look at: http://emcesd.com/tt2011/tt080111.htm Doug On 12/27/11 4:04 PM, Knighten, Jim L wrote: 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.
