The following table briefly describes each of the components of the U4432A probe labeled in the
above figure.
Component
Description
Module Connector
This component connects the U4432A probe to the U4431A Analyzer module. You plug this component into one of the two pod inputs
available on the front panel of the U4431A Analyzer module.
Coaxial Cables with SMA
Connectors
This component connects the U4432A probe to the DUT. There are 21 SMA cables in each probe.
Each cable connects to the positive or negative side of the differential probe input for a Tx or an Rx lane. In this probe, a pair of same
colored cables represent the positive and negative sides of the differential probe input for a given lane.
Refer to
“Labeling and Color Coding of Coaxial Cables"
on page 34 to know about the pins to use for probing various M-PHY
signals.
