Compliance Interposer
Optimal DDR4 validation requires analysis of the DDR4 signals as seen by the memory components. This allows for the highest confidence that the signals captured are representative of the signals on the target. Nexus Technology Memory Compliance Analyzer component interposers allow for Compliance Analysis of the DDR4 signals extremely close to the memory component’s… more…
DQ Data Acquisition
This interposer is capable of probing DQ read and write data at speeds in excess of DDR4-3200. The acquisition of DQ read and write data may be limited depending on the analyzer configuration.
Patented Socket Design
Nexus Technology’s patented, high-bandwidth, component interposer sockets greatly simplify the process of attaching the interposer to your target and make for a reusable interposer. Once the custom target socket is installed on the target, the interposer can simply be inserted into the custom target socket or be removed from the socket easily by hand – enabling the interposer to be used on multiple targets or quick swapping of logic analyzer and oscilloscope interposers on the same target.
