U4433A Differential ZIF Flying Lead Probe Description
The U4433A flying lead probe is a Keysight probing solution provided for the U4431A Analyzer
module. This module has two analysis pods located on its front panel that you can use to connect
two U4433A probes with the module.
A U4433A probe provides support for probing one to four lanes of a Tx or an Rx sublink of an M-PHY
link. A set of two probes provides support for probing one to four lanes of both Tx as well as Rx
sublinks using a single U4431A module.
A U4433A probe allows you to probe individual lanes. You connect a U4433A probe to the DUT by
connecting the leads of the probe via Zero Insertion Force (ZIF) tips to the DUT. You can make these
connections at multiple target points on the DUT. This allows flexible connections to individual
signals and eliminates the need to have signals routed to one probing point.
This probing solution does not require any designed connectors and probes signals without built-in
test points.
