The HP 16510B
Probing System
The standard HP 16510B probing system consists of probes, pods, probe
cable and grabbers. This system is passive (has no active circuits at the
outer end of the cable). This means that the pods and probes are smaller
and lighter, making them easier to use.
The passive probe system is similar to the probe system used with high
frequency oscilloscopes. It consists of a series R-C network (90.9 kΩ in
parallel with 8 pF) at the probe tip, and a shielded resistive transmission
line.
The advantages of this system are:
• 2 ns risetime with ± 5% perturbations
• 8 pF input capacitance at the probe tip
• signal ground at the probe tip for higher speed timing signals
• inexpensive removable probe tip assemblies
Probes and Probe
Pods
Probes and probe pods allow you to connect the logic analyzer to your
system under test without the HP 10269C Probe Interface. This general
purpose probing is useful for discrete digital circuits. Each probe and pod
assembly contains 16 data channels, one clock channel, and pod ground.
Probe Pod
Assembly
The pods, as they will be referred to for consistency, are the probe
housings (as shown below) that group 16 data, one clock line, and
grounds, corresponding to a logic analyzer pod.
