U7231A DDR3 Compliance Test Application
for Ininiium Series Oscilloscopes
Data Sheet
Introduction
Test, debug and characterize your DDR3 designs quickly
and easily
The Keysight Technologies, Inc. U7231A DDR3 compliance test application
provides a fast and easy way to test, debug and characterize your DDR3
designs. The tests performed by the U7231A software are based on the
JEDEC1 JESD79-3E and JESD79-3-1 DDR3 SDRAM Speciication. In
addition, the application features Custom mode, which covers crucial
measurements such as eye-diagram, mask testing, ringing and other tests
that are not covered in the speciications but are critical for characterizing
DDR3 devices. The test application offers a user-friendly setup wizard and
a comprehensive report that includes margin analysis.
DDR3 is an evolutionary upgrade to DDR2 and DDR1 memory systems.
DDR3 technology enables even higher bandwidth for data transfer than
DDR2 and allows you to build devices with even smaller chip footprints
that consume less power and generate less heat. DDR3 achieves these
advances with enhanced ine ball-grid array (FBGA) packaging, enhanced
on-die termination, self calibration and automatic self-refresh for improved
control of signal integrity.
Signal integrity is crucial for memory system interoperability. Reference
clock jitter measurements help you ensure that jitter is well within the
speciications, which is the key to reliable and interoperable modular
memory systems. At the same time, electrical and timing characteristics of
other signals are critical as well, to ensure the memory system functions
correctly and stays error free.
The U7231A DDR3 compliance test application is compatible with Keysight
Ininiium digital storage oscilloscopes.
