- Assume my oscilloscope is grounded, and the DUT is grounded as well (earth ground).
- I am using a standard 10 Mohm impedance 1:10 passive probe.
So, the ground terminal of the probe is in fact connected to earth.Is there any reason to connect the ground terminal of the probe to the ground of the DUT?

- I am using a standard 10 Mohm impedance 1:10 passive probe.
- So, the ground terminal of the probe is in fact connected to earth through the oscilloscope chassis.
- Is there any reason to connect the ground tip of the probe to the ground of the DUT?

Is it always necessary to use the ground terminal of the oscilloscope probe?
