The HP 16510B Probing System

Probes and Probe Pods

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 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.

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.
