Can you imagine that on the chassis and probes of your scope ?

It's very simple really. Just remember to keep the scope grounded to
the DUT ground AND the probe clipped to the power node (X1 setting on
the probe) at ALL times and bob's your uncle, you can't go wrong.
That way you are only placing about 15pf || 1M loading on the DUT.
HTH.

You must be meaning X10 setting. Common scope inputs as well as probes
are not designed to handle the typical peaks from power supplies at X1.
