robes and oscilloscope probes. Both have a passive design which
Probing System
means there are no active circuits at the outer end of the cable. The
passive design also enables the pods and probes to be smaller and
lighter, there by making them easier to use.
The logic analyzer probing system consists of flat ribbon probe cables,
a probe housing, probe leads, ground leads and grabbers. This passive
probing system is similar to the probing system used with high
frequency oscilloscopes. It consists of a series R-C network (100 kSZ in
parallel with 8 pF) at the probe tip, and a shielded resistive
transmission line. The advantages of this system include the following:
l
2 ns risetime with 25% perturbations
l
8 pF input capacitance at the probe tip
l
Signal ground at the probe tip for higher speed timing signals
l
Inexpensive removable probe tip assemblies
Probe Pod
Probes and probe pod assemblies allow you to connect the logic
Assemblies analyzer to your system under test without the HP 10269C Probe
Interface. This general purpose probing is useful for discrete digital
circuits. Each pod, as they will be referred to for consistency, contains,
16
probes (data channels), one clock channel, and a pod ground. See
the figure below.
