[. . . ] A complete set of triggers, including triggers for specific token (address) and data packet content, ensures you quickly capture your event of interest. SR-USB ­ USB 2. 0 Triggering and Analysis TDSUSBF USB 2. 0 Test Fixture. 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 Series oscilloscope, provides a robust set of tools for debugging embedded systems with USB 2. 0 serial buses, including: Automated serial triggering and decode for low-speed, full-speed, and high-speed USB 2. 0 signals 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! USB 2. 0 Compliance Test Fixtures A comprehensive compliance test fixture provides a probing solution for the Signal Quality, Inrush Current, Drop and Droop, Receiver Sensitivity, and Impedance Measurement test. Connectors are available for a data generator and Tektronix DSA8200 sampling oscilloscope with TDR module. [. . . ] 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. 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. USB decoded Event table showing all packet information with time-stamp information. 6 www. tektronix. com USB 2. 0 Application Software -- TDSUSB2, SR-USB, and DPO4USB Characteristics TDSUSB2 Characteristic Description Bus Trigger Options Characteristic Description Host, hubs, and devices Eye Diagram Test, Jitter (JK, KJ, and consecutive), Crossover Voltage Range, Signal Rate, End-of-Packet Width, Rising-edge Rate, Falling-edge Rate High-speed Tests Receiver Sensitivity, Chirp, Reset, Resume, Suspend, Packet Parameter, and Monotonicity test Inrush Current Check Data-sufficiency readout.
