U4421A Module Hardware Components
The Keysight U4421A MIPI D-PHY Protocol Analyzer and Exerciser module (hereafter referred to as
the U4421A module) provides digital serial stimulus and acquisition capabilities to test and debug a
D-PHY component independently or an integrated D-PHY based mobile design. This module can
emulate a master D-PHY component to provide stimulus to a D-PHY endpoint. You can also use this
module to capture D-PHY traffic and then analyze and debug D-PHY packets using various Keysight
tools and viewers available in the Keysight Logic and Protocol Analyzer GUI.
For information on Keysight AXIe chassis, U4421A module, how to set up the chassis, module, and
host computer and how to obtain and install the associated software components, see:
"Keysight
AXIe based Logic Analysis and Protocol Test Modules Installation Guide"
. This guide is available on
and is also installed with the Logic Analyzer software.
