@AmpBenzScientist I have several open source tools. They tend to add value the high end ones dont, but they dont and cant replace the high end ones.
For example I have the DSO nano which is my handheld scope.. great if you need a handheld and a bench scope wont do, very small, has most of the features you need including a rudimentary spectrum analyzer. But like anything cheap it isnt very sensative, and has a very limited frequency range. For any sort of RF/radio work it is useless and only a proper bench setup worth quite a bit is going to cut it. But yea owning both is a good idea and they server their respective purposes.
