Tektronix provides comprehensive, integrated tool sets to serve the needs
of engineers designing USB-based embedded systems as w ell as those
validating the physical-layer compliance of USB 2.0 serial devices to the
USB 2.0 standards.
The Tektronix TDSUSB2 USB 2.0 Compliance test application and selected
Tektronix oscilloscopes provide one-button compliance testing for USB 2.0

testing and allows engineers to perform the required tests efficiently and
reliably right on their be nch.
The Tektronix MSO/DPO4000 Series oscilloscopes with the DPO4USB
Serial Application Module and MSO/DPO5000 Series oscilloscopes with
the SR-USB application simplify analysis of USB 2.0 waveforms when
validating and debugging USB-based embedded systems. DPO4USB

The TDSUSB2 provides automated compliance testing for USB 2.0 serial
bus verification, including:
Fully compliant with USB-IF tests for USB 2.0 compliance testing
Automated eye diagram analysis verifies signal quality
Automated oscilloscope setups for various tests eliminate
time-consuming manual setups
Comprehensive test fixture enables quick setup and signal access for a
wide range of tests
High-speed tests: Signal Quality, Receiver Sensitivity, Chirp, Reset,
Resume, Suspend, Packet Parameter, and Monotonicity tests
Automatic rise and fall time measurements simplify tests
Automatic deskew for accurate measurements
Online help fu lly documents test procedures
User-configurable report formats for customization
User-configurable measurement limits for tolerance testing
Quick Pass/Fail tests substantiated with results make the TDSUSB2
application the preferred solution for USB 2.0 physical-layer validation.
In-depth analysis is possible with the statistical information about the tests
performed. The user-defined measurement limits also help to perform
tolerance testing on a design.
TDSUSB2 can be downloaded from www.tektronix.com and with the option
license you can easily install the software on your oscilloscope. After
allation, the application is accessible from the menu bar of the Tektronix
inst
Windows oscilloscopes. The user manual and other documents are copied
at the application insta llation location on the oscilloscope’s hard drive.

The SR-USB application provides a higher-level, combined view of the
individual signals that make up the USB bus, making it easy to identify
where pac
kets begin and end and identifying subpacket components such
as sync, PID, data, CRC, errors, etc.
Are you wasting time manually decoding the waveform? Tired of having
to visually inspect the waveform to count clocks, determine if each bit is
a 1 or a 0, combine bits into bytes, and determine the hex value? Let the
oscilloscope with the SR-USB application do it for you! Once you’ve set up a
USB bus, t
he MSO5000 or DPO5000 Series will decode each packet on the
bus, and display the value in Hex, Binary, or ASCII in the bus waveform.
