W2635A and W2636A DDR3 BGA Probe Adapter for Infiniium Oscilloscopes

• Provides signal access points for DDR3 DRAM x4, x8 and x16 packages using JEDEC-standard common BGA footprints to the oscilloscope
• 10mm and 11mm BGA probe adapter widths for different spacing requirement between the DRAM placements on the PCB or DIMM
• Buried resistors provide signal isolation and minimize capacitive loading
• Probing compatibility with InfiniiMax probe, which includes E2677A, N5381A, N5425A and N5426A differential solder-in probe heads
• BGA probe sockets for easy probe attachment. Information on sockets is available at the following R&D Interconnect Solutions website: http://www.rdis.com/ 
• S parameter models are available for use with InfiniiSim for de-embedding purposes.

The Agilent Technologies W2635A and W2636A DDR3 BGA probe adapters provide signal access to the clock, strobe, data, address and command signals to the DDR3 BGA package for making electrical and timing measurements with an Infiniium oscilloscope. With the DDR3 JEDEC specification (JESD79-3A) defined at the DRAM ballout, the BGA probe adapter provides direct signal access to BGA package for true compliance testing.

The W2635A and W2636A DDR3 BGA probe adapters are soldered in between the DRAM and PC board or DIMM raw card where the DRAM would normally be soldered. They are designed with the PCB or DIMM foot print on the bottom side and the DRAM footprint on the top side. The signals from the memory controller chip and DRAM are then passed directly to the top side of the BGA probe adapter where they can be accessed with the oscilloscope probes.
