Page 8: W4630 Series Ddr4 Bga Interposer - Introduction
DRAM would normally be soldered. The interposer is designed to be soldered to the PCB footprint for the DRAM on top of either the DDR4 riser included with the W4630 series BGA interposer or an optional Grypper socket (not included with the interposer). The DRAM being probed is then soldered to the top side of the interposer. -

Page 31: Loading A Configuration File
Because of these dependencies, there is no single logic analyzer configuration file setup for the W4630-series interposers. A set of DDR4 x4 and x8 configuration files is provided with the Keysight B4621B Decoder software. To obtain this set of configuration files, you must install the B4621B software (licensing of this software is not required for obtaining these configurations). - Page 32 Setting Up the Logic Analyzer for W4630 Series Probes Keysight W4630 Series DDR4 DRAM BGA Interposers Installation Guide...
