TekExpress software ordered with Option USB-TX and USB-RMT provides an automated, simple, and efficient way to test USB 3. 0 transmitter and receiver hosts and devices consistent with the requirements of the SuperSpeed Universal Serial Bus Electrical Compliance Test Specification (CTS). *1 See host system requirements in Ordering Information section. Receiver testing is a requirement for SuperSpeed USB certification. The 10x increase of data rate (5 Gb/s) makes it critical that the receiver properly interprets the incoming bit stream. [. . . ] The user also has the flexibility to change the SJ amplitude of the compliance test points. For example, a compliance test can be ran with 20% margin by easily changing the amplitude of jitter at each frequency and saving that setup. The setup can be recalled at a later point in time and the test can be run under tighter conditions. Complex SSC Profiles One source of system failures or PHY non-compliance is SSC. With USB-RMT, the user can quickly modify the SSC deviation and/or frequency modulation in order to determine if the SSC is the cause of bit errors. Furthermore, the AWG with SerialXpress can be used to generate complex df/dt profiles in order to fully characterize the receiver's pll. Stress the RX over Various Channel Configurations Using the AWG and USB-RMT enables the stressing of the receiver under various channel and cable conditions. The AWG is uniquely suited to stress the receiver by emulating the channel and USB cable in software. By using S-parameters or allowing ISI to be specified in absolute terms (for example . 3 UI) users can quickly configure a test under multiple different operating conditions without requiring physical hardware channels or USB cables. Another benefit from using software emulation is that variability from mechanical wear or different physical channels and cables is not an issue. Test Report Ellisys Protocol Analyzer Error Detection An alternative to using the scope-based error detection is to use an external USB 3. 0 protocol analyzer. The Ellisys USB Explorer 280 5 Gb/s Error Detector is completely integrated into USB-RMT and reports both 8b/10b character errors and disparity errors while ignoring SKP ordered sets. Test Status Once the test has been properly configured, USB-RMT will automatically set up and configure the test equipment. As the test points are being executed the USB-RMT will update the results dynamically. The results of the tests are shown in a tabular format and a graphical display. The graphical display supports both logarithmic and linear scales. The Test Status screenshot above shows a compliance test that has passed all of the required frequencies with the exception of 33 MHz. A supported configuration includes a DPO/DSA70000B Series Digital Serial Analyzer www. tektronix. com 5 Data Sheet (or other supported oscilloscope) equipped with DPOJET (Jitter and Eye Diagram Analysis Tools). USB-TX also includes USB3 Essentials DPOJET Measurements and Setup Library. The following table outlines the key differences between the USB3 and the USB-TX software solutions. USB3 Essentials is included with USB-TX and thus all product features included with USB3 Essentials are also included with USB-TX.

The oscilloscope is controlled through the TekExpress automation framework. The TekExpress software provides a Graphical User Interface (GUI) and provides an intuitive workflow through setup and testing. X Setting up the Bench When setting up a test, nothing can be simpler than hooking up the test system by looking at a schematic. View the schematic of the selected test with a push of a button.
