P7225 2.5 GHz 10X Active Probe User Manual

This method is very useful when making many measurements on the

same package. Using a ground plane on the IC package makes

probing the IC package e asier and avoids adding unnecessary ground

lead length and distortion.

SureFoot Grounding

If you cannot use the re commended low-inductance grounding

method, you may ground the probe to the IC package under t est

using a SureFoot adapter. Refer to Figure 9.

Figure 9: Using a SureFoot adapter for grounding

Use a SureFoot adapter at the end of a short ground lead t o connect

using an adjacent circuit ground because it is the shortest ground

path possible.
