A challenge we test guys have is providing systems and information that are "immediately actionable" by engineers. In that context, if we can provide test rigs that support sufficient reproducibilty then engineers can use "trial and error" which is typically the approach used in complex systems that are programmable, particularly systems that are non-linear and have non parametric distributions in their metrics. Just being able to reproduce non-parametric distributions is quite an achievement. But that's not typically good enough as one has to prove the non-parametric distributions are self similar. And then we can get thousands or more of them. (The kolmogorov-smirnov helps with this
https://en.wikipedia.org/wiki/Kolmogorov%E2%80%93Smirnov_test I would say, "Thank God for computers" but God didn't build computers. A bunch of predecessors did so "Thank God for them")
All of this requires a lot of "computer control" over the "RF channels."
