Build the diffprobe from this blog post: http://blog.weinigel.se/2016/03/16/ghz-differential-probe-3.html with a few mods. I don't have a network analyzer yet, or anything near GHz so I can't really test that ... but it works wonderfully for fast differential signals like USB or HDMI and floating shunt measurements etc.
Before I used this HP 1141A with it's own PSU. Took a few minutes to set up and plug in, mine is powered directly by the scope with a DC-DC converter.
