I was looking at getting a Fluke LRAT-2000. Maybe that does the stuff
you want? It does work with, identifies and can load test POE. Maybe it
wouldn't work with passive POE though. I have no idea. There's a really
good deal on it at Amazon right now:

Yep that's what I'm looking for.
I can do it old school style with a vector analyzer.... but as an
example, just the NEXT testing requires twelve different connection
arrangements. You have to inject a signal on one pair then test a
different pair for signal crosstalk. Repeat for all combinations of
pairs. And that's just one test.
Most of the testers I found require DC connectivity to the remote end,
mainly to operate the relays in the remote end. Ones which can test
without a remote by plugging both ends into the tester are rare. And
so on.
It's just frustrating that these testers are so close to what I need
yet can't work because of what I need to test.

Well, then you’ve never done a wiring job for a business or school

But yeah, I assume Forrest is trying to test that his GbE POE
doesn’t degrade any of the specs like crosstalk, attenuation,
return loss, etc., or to quantify how much you have to derate the
100 meter distance to compensate for inserting the POE?
I used to have a Pentascanner, but the Fluke website says that
line was EOM in 2004 and EOS in 2008. Way to make me feel old!
No idea if the current DSX-5000 can test through the transformers
in a gigabit POE, or be convinced to run the qualification tests
even if the DC tests fail.

The only thing that matters to me is iPerf. :-) Granted, I'm not
creating components and troubleshooting why when they're in place
they may not be getting full throughput anymore.

I'm already doing that, but it doesn't help to verify things like
near end crosstalk, insertion loss, etc. etc. etc.
It's just a 'everything is fine' vs 'what does the cable look
like' test.

Ok, everyone.....
I'm looking for one or more Gigabit Ethernet testers to test
product with which will actually test (signal-wise) a gigabit
link for spec conformance.... The catch? It has to work with a
gigabit injector in the middle, since it's really about
testing the injector's performance instead of a cable.
Most of the gigabit cable validators I've seen will completely
refuse to run the signal validation tests on a cable which
doesn't pass electrical continuity. Unfortunately, once you
insert a gigabit injector the cable electrically looks like
all 4 pairs are shorted, and there isn't any continuity to the
far end.
Does anyone have a CAT5 cable tester which works *through* a
PoE? Or are willing to test theirs on a (unpowered) injector
to see what happens?
