Keysight U4164A Logic Analyzer - At a Glance

The Keysight U4164A logic analyzer is a 136 channel AXIe based high speed state and timing logic
analyzer with new features such as:
•
•
•
•
The module can be used as a general purpose logic analysis system as well as for debug, validation
and analysis of DDR and LPDDR memory systems. It allows maximum DQ visibility with simultaneous
Read and Write traffic capture for DDR4 and LPDDR4. It supports up to 4 Gb/s State Mode and 10
GHz Timing Mode.
The U4164A has 2 M to 400 M sample memory depth (depending on the license option chosen).
Features
Some of the main features of the U4164A module are as follows:
•
•
•
•
•
•
•
•
To know about these features in detail, refer to the U4164A Data Sheet (5992-1057EN) on

DDR4 and LPDDR4 probing for data rates over 2.5 Gb/s using the new Quad sampling state mode
and single touch probing
Deeper memory
Quarter channel 10GHz Timing mode
Deskew of timing traces by individual channels
136 channels per module
Expandable to 408 channels (as a 3-card set in the AXIe chassis).
A new state sampling clock mode - Quad Sample that allows four samples per clock edge.
A new Timing (Asynchronous) sampling option - Quarter Channel Timing Mode with the 01G or
02G license.
4 Gb/s (2.5 GHz) maximum state acquisition speed (with the "02G" license).
2.5 GHz timing analysis in Full Channel timing mode, 5.0 GHz timing analysis in the Half Channel
timing mode, and 10.0 GHz timing analysis in the Quarter Channel timing mode.
A state sampling clock with the following clock qualifiers:
• Four clock qualifiers - Pods 2, 3, 4, and 5 of the clocking module
• An additional "RESET" clock qualifier - Pod 7 of the clocking module
A new setting called Clock hysteresis for the state sampling clock on Pod1 of the U4164A module.
Using this setting, you can set a value (in milliVolts) between 0 and 1 volts around the clock
threshold.
