Connecting the U4432A Probe to the U4431A Module and DUT
The U4432A probe connects to the DUT via 50-ohm coaxial cables using SMA connectors.

While detaching a probe's module connector from the U4431A module, disengage the screws
NOTE
completely from the module and then pull the module connector straight out to remove.
Components on the U4432A probe are sensitive to the static electricity. Therefore, take necessary
CAUTION
anti-static precautions, such as wear a grounded wrist strap, to minimize the possibility of
electrostatic damage.

Plug the module connector (refer figure on
the front panel of the U4431A module.

Hand-tighten the thumb screws on both sides of the module connector of the probe.
Connect the appropriate coaxial cables (with SMA connectors) of the probe to the DUT. (You can
refer to
page 34
to verify which coaxial cables to connect.)
a Based on the link width needed, connect the set of cables for M-Phy data lanes 0 to 3.
You may leave the coaxial cables for the unused data lanes disconnected.
b Connect the cable for the DUT's supply voltage sense signal (labeled Vsense) to the DUT's
power supply. The DUT sends this signal to the module to indicate when the module can
actively send M-Phy signals to the DUT.
