hi. my Oscilloscope input channel impedance is 1 ohm.what can be damaged?
这是一个好问题吗？
We will need some more info.
• What make and model is it?
• Was there different impedance before?
• Are you sure it is not 1 MΩ???

Sounds like an input amplifier is fried due to overvoltage. If it was a mechanical short it would be near zero ohms, but you have a short through a semiconductor junction.
这个答案有帮助吗？
