FS2331 Probe Description

The FS2331 DDR DIMM Probe allows you to perform state and timing analysis measurements on Double Data Rate DRAM DIMM busses using an Agilent logic analyzer.

Probe Feature Summary

∙Quick and easy connection between the DDR 184 pin DIMM connector and Agilent Logic Analyzers.

∙Complete and accurate state analysis up to 333Mhz (PC2700).

∙Complete and accurate 4 GHz timing analysis.

∙Compatible with all 184-pin, 2.5V DDR SDRAM DIMM's up to 333 MHz.

∙Built-in support for probing Chip Select lines of other DIMM slots.

∙Data groups and their strobes matched to better than 50ps, address and commands matched to better than 180ps.

∙All signals are provided to the logic analyzer unbuffered.

∙Registered and non-registered DIMMS are supported.

∙User configurable capacitor pads allow modeling of 1, 2, and 4 rank (stacked) DIMMS for signal integrity validation with EyeScan.

∙DDR Commands are always visible. Switches select state analysis acquisition of data writes only, reads only, or both writes and reads.

∙Uses Agilent "Eye Finder" technology to locate tight DDR data valid windows for optimal state data capture and to help identify bus signals with marginal timing needing closer examination.

∙Probe can be used with Agilent EyeScan technology to provide eye diagram of DDR and address/command signals.

∙Both x4 and x8 SDRAMS are supported.

∙Read and write burst type is tracked in real time and each cycle of a burst (in both state and timing mode) is sent to the analyzer.
