Introduction Welcome to the TDSUSB2 Universal Serial Bus Measurements Package
Welcome to the TDSUSB2 Universal Serial Bus Measurements Package
TDSUSB2 Universal Serial Bus Measurements Package is a Sun Java-based application that runs on the
supported instruments connected to a PC. You can use the application software with the compliance
test fixture to take the following measurements:
Signal Quality
Inrush
Droop
Drop (supported by the test fixture only)
Receiver Sensitivity
Impedance Measurement using Time Domain Reflectometry (TDR), supported by the application
only with the test fixture
Chirp measurements
Packet Parameter
Resume
Reset from Suspend
Reset from High Speed
Suspend
The application runs on the oscilloscope and displays on the lower part of the screen. The oscilloscope
application runs on the upper part of the screen.

Conventions
Online help uses the following conventions:
Refers to the software part of the TDSUSB2 Universal Serial Bus Measurements Package as the
TDSUSB2 application or as the application.
When steps require a sequence of selections using the application interface, the ">" delimiter marks
each transition between a menu and an option. For example, one of the steps to recall a setup file
would appear as File > Recall.
Unit under test (UUT) refers to the USB2.0 device under test, hub under test, host under test, and
port under test.
SOF refers to the Start of Frames exchanged between the host controller and the device when the
device is connected to the host and enumerated by the test mode software.
