[. . . ] DPO4USB offers automated trigger, decode, and search for low-speed, full-speed, and high-speed USB buses, enabling fast and efficient validation and debug. SR-USB USB 2. 0 Triggering and Analysis Automated Trigger and Decode for USB 2. 0 Designed for use with the MSO/DPO5000 Series Oscilloscopes DPO4USB USB 2. 0 Triggering and Analysis Automated Trigger, Decode, and Search for USB 2. 0 Designed for use with the MSO/DPO4000 Series Oscilloscopes Data Sheet TDSUSB2 compliance test results. Measurement Select menu for the Signal Integrity test. 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 TDSUSB2 Automated USB eye diagram analysis. Online help fully 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. [. . . ] USB 2. 0 Decode The DPO4USB USB Serial Application Module 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 identifying subpacket components such as sync, PID, data, CRC, errors, etc. 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?Once you've High-speed USB decoded display, automatically displaying bus content in any of several digital formats. set up a USB bus, the MSO4000 or DPO4000 Series will decode each packet on the bus, and display the value in Hex, Binary, or ASCII in the bus waveform. www. tektronix. com 5 Data Sheet 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 a DPO4USB USB Serial Application Module, you can enable the oscilloscope to automatically search through the acquired data for user-defined criteria including serial packet content. Rapid navigation between marks is as simple as pressing the Previous () and Next () buttons on the oscilloscope front panel.
