P6249 4 GHz 5X Active Probe Instruction Manual

This method is very useful when making many measurements on the

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.
