4 Setting up an E5381A Differential Flying Lead Probe Configuration for U4421A Module
28 Keysight U4421A MIPI D-PHY Analyzer and Exerciser Hardware and Probing Guide
The following table maps the channel number of the flying leads with their color coding and lists the
D-PHY signal connection to be probed by each of these cables.
D-PHY Signals to Flying Leads Mapping
In a E5381A probe, there are:
• Two flying leads for probing D-PHY clock positive and negative signals.
• Two flying leads for probing D-PHY data lane 0 positive and negative signals.
• One flying lead each for probing D-PHY data lane 1, 2, and 3, if used.
