same package. Using a ground plane on the package makes probing
the package easier and avoids adding unnecessary ground lead length
and distortion.

SureFoot Grounding
If you cannot use the recommended low-inductance grounding
method, you may ground the probe to the package under test using a
SureFoot adapter. Refer to Figure 6.

Figure 6: Using a SureFoot adapter for grounding
Use a SureFoot adapter at the end of a short ground lead to connect
directly to the package ground. This method is preferred over using
an adjacent circuit ground because it is the shortest ground path
possible.
