Logic Probes

What is a Logic Probe?

A logic probe is a tool used in conjunction with mixed signal instruments, like oscilloscopes and ScopeCorders, to capture digital signals. The effectiveness of waveform measurement depends significantly on the quality of the probe, its interaction with the measuring instrument, and its connection to the circuit under test.
