Probe and Pod Grounding
Each pod is grounded by a long black pod ground lead. You can connect the
ground lead directly to a ground pin on your target system or use a grabber.
To connect the ground lead directly to grounded pins on your target system,
you must use 0.63 mm (0.025 in) square pins, or use round pins with a
diameter of 0.66 mm (0.026 in) to 0.84 mm (0.033 in). The pod ground lead
should always be used.
Each probe can be individually grounded with a short black extension lead
that connects to the probe tip socket. You can then use a grabber or the
grounded pins on your target system in the same way you connect the data
lines.
When probing signals with rise and fall times of 1 ns, grounding each probe
lead with the 2-inch ground lead is recommended. In addition, always use
the probe ground on a clock probe.
