E5381A Differential Flying Lead Probe - Introduction
The E5381A is a 17-channel differential flying lead probe that you can use with the U4421A module
to probe D-PHY signals.
You can use this probe to probe differential as well as single-ended signals. A single E5381A probe
provides support for probing one to four data lanes and one clock lane of a D-PHY link.
You connect an E5381A probe to the DUT by connecting the leads of the probe via the supplied
probe accessories to the DUT. This allows flexible connections to individual signals
When to use an E5381A Flying Lead Probe
An E5381A
flying lead probe is suitable for use in situations such as:
• When you want to probe individual signals from multiple randomly located points on the target
system. You can connect the leads of the probe directly to these multiple points and thereby
eliminate the need to have signals routed to one probing point.
• When there is a space constraint on the DUT and the footprint for the E5405A soft touch probe
cannot be incorporated on the DUT. In such situations, you can use E5381A probe and connect
individual flying leads to the DUT.
