Connecting the Preprocessor to the Logic

Analyzer

This section shows you how to connect the preprocessor to the logic

analyzer. It consists of the following:

• Connecting the high-density cables to the preprocessor interface

• Connecting the high-density cables to the logic analyzer

This section shows connection diagrams that identify connections to

each individual logic analyzer supported by the preprocessor

interface. They are shown in the following order:

• HP 1660A/AS/C/CS logic analyzers

• HP 1661A/AS/C/CS logic analyzers

• HP 1662A/AS/C/CS logic analyzers

• HP 1670A/D logic analyzers

• HP 1671A/D logic analyzers

• HP 1672A/D logic analyzers

• One-card HP 16550A analyzer

• Two-card HP 16550A analyzer

• HP 16554A/55A/56A (one-card)

• HP 16554A/55A/56A (two-card)

Number of Pods Used/Required

The type of measurement to be made determines the number of logic

analyzer pods to be used. State measurements require four pods.

Full timing measurements require eight pods. If fewer than eight pods

are available for timing, the logic analyzer will truncate the pods

allocated. In this case, viewing the logic analyzer FORMAT menu

shows the pod allocations. If the allocations will not acquire the

desired signals, the allocations can be altered manually.
