Since I did not spend $30,000 on my scope, all 3 'scopes I've got are the same sensitivity as most hobby scopes on the market, and my signal vanishes into a straight line at about 50cm distance from the signal source, even though I know there's still a signal available somehow at 2 meters distance. | |

All scope inputs are incredibly sensitive, showing microvolts, so I struggle to see where any x1 probe is ever needed. Sometimes I use an x100 probe just to get more bandwidth. | |
