Product description

The Tektronix USB 2.0 compliance test application (Opt. USB2) and selected Tektronix oscilloscopes provide one-button compliance testing for USB 2.0 devices as specified by the USB-IF. The USB software automates the compliance testing and allows engineers to perform the required tests efficiently and reliably right on their bench.

The Tektronix MDO4000 Series oscilloscopes with the DPO4USB Serial Application Module, MDO3000 Series oscilloscopes with the MDO3USB Serial Application Module, 5 Series MSO with the 5-SRUSB2 application, and MSO/DPO5000, DPO7000C, and DPO/DSA/MSO70000C/D/DX Series oscilloscopes with the SR-USB application simplify analysis of USB 2.0 and 3.0 waveforms when validating and debugging USB-based embedded systems by providing trigger, decode, and search for low-speed, full-speed, high-speed, and SuperSpeed USB buses. MDO3USB offers automated decode and search for low-speed, full-speed, and high-speed USB buses, as well as triggering on low-speed and full-speed buses. DPO4USB offers automated trigger, decode, and search for low-speed, full-speed, and high-speed USB buses, enabling fast and efficient validation and debug.

USB2 – Automated USB 2.0 Physical Layer compliance testing

USB compliance testing has some unique measurement challenges:

• Designers must quickly and accurately perform all compliance tests recommended by the USB Implementers Forum, Inc. (USB-IF) before they can use the “certified” USB-IF logo on their packaging
• Characterization of these electrical signals includes mask testing and parametric testing, for low-speed, full-speed, and high-speed hosts, devices, and hubs
• Signal speeds range from 1.5 Mb/s (low-speed) to 480 Mb/s (high-speed)

The USB2 application software 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 against standard USB-IF eye masks or custom masks
• 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, Reset from High Speed, Reset from Suspend, Resume, Suspend, Packet Parameter, and Monotonicity tests
• Automatic signal generator control for receiver sensitivity simplifies testing
• Online help fully documents test procedures
• User-configurable measurement limits for tolerance testing
• Supported on Windows 7 (64-bit) and Windows 10 (64-bit) operating systems

Quick Pass/Fail tests substantiated with results make the USB2 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 and custom mask testing also help to perform tolerance testing on a design.

USB2 compliance test fixtures

The Tektronix TDSUSBF test fixture set provides a probing solution for the Low- and Full-speed Signal Quality, Inrush Current, Drop and Droop, Receiver Sensitivity, and Impedance Measurement test. The TDSUSBF test fixture set is ordered separately.

The High-speed signal quality fixture set (USB2SIGQUAL) provides the necessary SMA-based connection for performing Eye Diagram and other signal quality measurements. The USB 2.0 / 3.0 Drop-Droop fixture (USB2/3_DD) from www.fixturesolutions.com provides sufficient loads for testing voltage drop and droop levels while testing Host or Hubs (downstream ports supplying VBUS).

SR-USB USB 2.0 and 3.0 triggering and analysis

Debugging USB-based embedded systems designs provides some complex measurement and analysis challenges:

• Capturing specific USB addresses and data
• Displaying the elements of the USB message in an understandable format, in a variety of formats, for a wide variety of engineers and technicians
• Time-correlating USB messages with analog and digital signals in the embedded system
• Capture long time windows of USB traffic and then find specific events within the acquired data

The optional SR-USB application software, installed in an MSO/DPO5000, DPO7000C, or DPO/DSA/MSO70000C/D/DX Series oscilloscope, provides a robust set of tools for debugging embedded systems with USB 2.0 and 3.0 serial buses, including:

• Automated serial triggering and decode for low-speed, full-speed, and high-speed USB 2.0 signals
• Serial triggering and decode for SuperSpeed USB 3.0 signals (8b/10b)
• Trigger on all the critical elements of a USB bus such as address, data, etc.
• Decode all the critical elements of each USB message. No more counting 1s and 0s!
• Search through long acquisitions using user-defined criteria to find specific messages
• Event table shows decoded serial bus activity in a tabular, time-stamped format for quick summary of system activity

USB serial triggering

Trigger on packet content such as sync, reset, suspend/resume, token (address) packets with specific address and endpoint, specific data content, handshake packets, special packets, and errors.

USB serial decode

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 packets begin and end and identify 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, the MSO/DPO5000, DPO7000C, or DPO/DSA/MSO70000C/D/DX Series will decode each packet on the bus, and display the value in Hex, Binary, or ASCII in the bus waveform.

USB 2.0 Event table

In addition to seeing decoded packet data on the bus waveform itself, you can view all captured packets in a tabular view much like you would see in a software listing. Packets are time stamped and listed consecutively with columns for each component (Time, PID, Address, Payload, and Errors).

USB 2.0 search

USB packet content triggering is very useful for isolating the event of interest, but once you’ve captured it and need to analyze the surrounding data, what do you do? In the past, users had to manually scroll through the waveform counting and converting bits and looking for what caused the event. With the SR-USB application installed, you can enable the oscilloscope to automatically search through the acquired data for user-defined criteria including serial packet content. Each occurrence is highlighted by a search mark. Rapid navigation between marks is as simple as pressing the Previous (←) and Next (→) buttons on the oscilloscope front panel.
