Maybe something like EXFO or Anritsu. Spirent and Agilent would be best, but
probably too expensive if this is the only use-case.

Not possible on iPerf. Network testing shouldn't be done with TCP, because
then you don't know what you're testing, are you testing TCP stack of the host
or network?
But writing performing UDP software is quite hard. You cannot use UDPSocket
like iperf does, it just does not work, you are lucky if you reliably test
I'm not aware of modern performing UDP testing software, which is shame,
because it's possible to do today, it won't be portable and will impose
specific limitations on what hardware to use, but it'll be fast and will
deliver reliable results and quite accurate jitter measurement.
