Agilent probes access DDR2, DDR3 BGA memories
-- Test & Measurement World, 2/13/2008 4:01:00 PM
Used with oscilloscopes and logic analyzers to perform physical layer and functional test, these DDR2 and DDR3 BGA probes from Agilent Technologies provide direct access to the balls of DRAM chips with low loading and minimal impact to signal integrity.
The probes provide signal access points to the clock, strobe, data, address, and command signals of the DDR3 DRAM for true compliance testing with an oscilloscope. The logic analyzer provides timing and protocol views of the DRAM activities. The DDR2 BGA probe enables simultaneous access to the oscilloscope and to the logic analyzer’s full compliance and protocol validation.
The DDR2 BGA probe provides probing of x8 and x16 DRAM packages. Model numbers W2631A and W2632A, when combined with Agilent's E5384A and E5826A logic analyzer adapters, support command and data probing for x16 packages; model numbers W2633A and W2634A provide access to command and data buses for x8 packages. When used with high-bandwidth solder-in InfiniiMax probes, all four DDR2 BGA probe variants allow probing with the oscilloscopes.
The DDR3 BGA probe supports different packages. The W2635A x8 BGA probe provides support for x4 and x8 DRAM package. The W2636A x16 BGA probe adapter provides support for x16 DRAM packages. Each comes in two different widths—10 mm and 11 mm—to satisfy the different spacing requirements between DRAM chips.
The W2631A, W2632A, W2633A, and W2634A cost $1999 each. The W2635A and W2636A cost $1500 each.
