General-purpose probing requires connecting probe leads to individual signal lines. It is
generally the most cumbersome method, but it is also the most flexible. Because of the
passive design of the probe, there are no active circuits at the outer end of the cable.

The advantages of this are:
High input impedance.
(See Equivalent Load.)
Signal ground at the probe tip for high-speed timing signals.
Inexpensive, removable probe tip assemblies.
