Using the USB3 Option
Using the USB3 Option Overview
USB 3.0 (also referred to as SuperSpeed USB) is a standard striving for a bus bit rate of 5 Gb/s. The standard is
backward compatible and retains use with hubs and other related devices.
So as to accommodate very high bit rate and reduce bus turnaround time limitation, USB 3.0 defines separate
dual simplex transmission and reception on differential lines. The additional lines (equipped with the new 3.0
standard) are run parallel to the USB 2.0 lines for forward and backward compatibility.
Note: Ask your local LeCroy representative for more information about any Serial Data Debug Solution
Protocols or Toolkits using the Contact LeCroy for Support (on page 199) topic.

USB3 Decoder Right-Hand Dialog
The USB3Decoder right-hand dialog provides detailed controls and setup conditions as follows:

Configure the Probe Selection control based on whether you're using One Differential Probe or Two
Single Ended Probes.

Use the Data Is Scrambled check-box as desired.

necessary.
