• It has two modes of operation:  As Logic Analyzer interface (FS2510) and standalone that runs off the PC via USB (FS2700).  The FS2520 combines both of these features into a single unit.
• Follows the system at power on from I2C to the I3C transition never missing any traffic
• Signals can be probed from anywhere on the motherboard or at the DDR5 DIMM/SODIMM
• Hundreds of registers with thousands of bit settings decoded for your convenience
• Supports all the Devices/Functions on a DDR5 RDIMM/LRDIMM/SODIMM/UDIMM
• The latest set of Device/Function registers are always available

• PC Requirements: Windows 10 PC with USB
• FS2710/FS2720 Keysight Logic Analyzer requirements:
  • 1 M9505A five-slot AXle chassis
  • 1 U4164A Logic Analyzer Modules
  • 1 U4201A cable

• Two Levels of Triggering
• Trig Out
• Storage qualification capture on any slot, function and even register address

Standalone Triggering Features

• Trigger on any I3C command
• Trigger on traffic to any slot or function (ex. Slot 0 RCD or Slot 2 PMIC)
• Trigger on any Read or Write to a specific slot and function via register address

Standalone Storing Qualification Benefits

• Store only traffic of interest
• Store only Traffic to a particular slot or function (ex. All traffic to Temperature Sensor slot 1)
• Store all traffic to a particular function (ex. both RCD’s on a channel)

• One POD to the U4164A
  • A single machine with its own clock run in State mode
  • Traditional Inverse assembler with register decode
• Serial to Parallel conversion with all command codes and data
• Easy Triggering and store qualification on the Logic Analyzer
• Correlate with DDR5 bus traffic from FuturePlus slot interposers

• Flex Tip
  • From DDR5 DIMM
  • Anywhere SDA/SCL is located on the motherboard
