Ground lead length
When you are probing a circuit, you should
always use as short a ground lead as possible
between the probe head and circuit ground.
(See the illustration for the effects of lead length
on waveform distortion.)
The series inductance added by the probe tip
and ground lead can result in a resonant circuit;
this circuit may cause parasitic ringing within
the bandwidth of your oscilloscope.
