16860A Series Probing Options (Continued)
DDR/LPDDR interposers and probes
The following provides a high-level overview of memory probing components and 16860A
Series logic analyzer compatibility. To ensure you order the correct quantity and combination of
components for your specific DDR/LPDDR implementation, refer to the data sheet for a specific
component for more detailed information. The following include 16860A Series configuration
files for easy setup. Refer to page 5 for logic analyzer state speed option requirements.

1. Refer to the data sheet for a given interposer for information on specific signal access.
2. The required U4201A cables may be more than what a given 16860A Series logic analyzer will support. If the
number of U4201A cables is more than what the analyzer supports, some signals will not be available for that
model. The maximum number of U4201A cables per analyzer are two for the 16862A, three for the 16863A
and four for the 16864A.
