You need a signal level meter not a tester. Used to be a few good manufacturers but because of mergers and going out of business over the years the one left that I would recommend is Sadelco. The model 2000 should handle whatever you are going to do.

By the way give a holler if you don't understand something. This kind of work is going to be a lot different than what you may be used to.
