Ground Lead Length

When you are probing a circuit, always use as short a ground lead as

possible between the probe head a nd circuit ground.

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 host instrument. Refer to Figure 6.
