I used something like this to test noise rejection in power supplies, which turns out to be quite hard unless literally every wire and component is shielded. Plus instrument you are trying to measure the results gets screwed over too
I did think about a portable device to fuck with Leftist internet connections
the external termination box looks like this in the UK
It you insert an sleeve insulated pin into the coaxial cable and pierce the signal wire, then you should be able to overload their internal router/NTU with an ESD device
