IMHO the oversight in this response is that having good tools to investigate problems essentially equates to (1) tens of thousands of dollars in hardware; (2) permanent lab space; (3) the relevant base capital; (4) supply chain access; (5) a university equivalent level education in physics and electronics; and (6) at least a few years to hone your craft. This is realistically a five to ten year commitment, perhaps a little less full time if enthused and adequately capitalized.
