General-purpose probing

	General-purpose probing
NOTE:	For all Agilent logic analyzers except 16517A, 16518A, 16760A, and
	16753/54/55/56A.
	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. There are no active circuits at the outer end of the cable due to the
	passive design of the probe.

The advantages of general-purpose probing are:

•High-input impedance as shown in the equivalent load model below.

•Signal ground at the probe tip for high-speed signals.

•Inexpensive, removable probe tip assemblies.
