You can buy US manufactured oscilloscopes from keysight. A 50% price hike on one of them is enough money to buy a new car, with enough left over for a few months of bay area rent. There are much better uses for that money than throwing it into the money furnace of tariffs, like paying employees or buying half a dozen lower-end scopes manufactured in Asia.
If customers can afford a 50% price hike on lower end oscilloscopes, would that create a small domestic market? Like, I don’t really mind spending an extra 200 bucks on a 200 buck oscilloscope, or even an extra 300 bucks.
