Appendix D: Probe Basics

TDS3000B Series User Manual

D- 3

Probe Guard

A guard around the probe body provides a finger barrier for
protection from electric shock.

Guard

WARNING.

To avoid electric shock when using the probe, keep fingers

behind the guard on the probe body.

To avoid electric shock when using the probe, do not touch metallic
portions of the probe head while connected to a voltage source.

Ground Leads

Always use a ground lead when you probe a circuit to minimize
noise pickup and signal aberrations. Connecting the ground lead to a
point near the signal source usually provides the best results.

Long ground leads can cause false ringing and aberrations in the
acquired waveform that are not in the actual signal. To see the best
signal fidelity, use the shortest possible ground lead.

Long Ground Lead

Short Ground Lead
