This document provides information for the following Agilent products:
The document provides a user's guide for Agilent LPDDR BGA probes (W2637A and W2638A) and the W2639A Oscilloscope Adapter Board. These tools enable logic analyzer state and timing measurements of x16 and x32 DRAM buses using JEDEC standard common footprints. The guide details equipment requirements, mechanical considerations, soldering instructions for the probes, and connection procedures for both logic analyzers (E5384A/E5826) and Infiniium oscilloscopes.
| Transfer Rate (with Logic Analyzer) | 255 Mb/s |
|---|---|
| Transfer Rate (with Oscilloscope Adapter) | 500 Mb/s |
| Bandwidth (3 dB) with Logic Analyzer | 510 MHz |
| Bandwidth (3 dB) with Oscilloscope Adapter | 1.5 GHz |
| Rise time with Logic Analyzer | 686 ps |
| Rise time with Oscilloscope Adapter | 233 ps |
| Input Impedance (with Oscilloscope Adapter) | 200 Ω |
The W2637A supports x16 DRAMs, while the W2638A supports x32 DRAMs.
The system requires an Agilent 80000 or 90000A Series oscilloscope.
One order of W2639A is sufficient because each kit includes two boards, and the W2637A uses only two.
