Serial Triggering and Analysis Application Modules AERO AUDIO AUTO AUTOMAX COMP EMBD FLEX USB ENET Datasheet Key features 2 Automated Serial Triggering, Decode, and Search options for I C, SPI, 2 CAN, LIN, FlexRay, RS-232/422/485/UART, MIL-STD-1553, I S/LJ/ RJ/T DM, USB, and Ethernet. Trigger on all the critical elements of a serial bus such as address, data, etc. Triggering on a specific transmit data packet going across an RS-232 bus. A complete Decode all the critical elements of each message. No more counting1s set of triggers, including triggers for specific serial packet content, ensures you quickly and 0s capture your event of interest. Search through long acquisitions using user-defined criteria to find specific messages. Search mark table provides a tabular view of the Serial triggering events found during an automated search. Trigger on packet content such as start of packet, specific addresses, Export Search Mark table data to .csv file. specific data content, unique identifiers, etc. on popular serial interfaces 2 such as I C, SPI, CAN, LIN, FlexRay, RS-232/422/485/UART, MIL- Event table shows decoded serialbus activity in a tabular, time- 2 STD-1553, and I S/LJ/RJ/TDM, USB, and Ethernet. stamped format for quick summaryof system activity. Export Event table data to .csv file. Bus display Provides a higher-level, combined view of the individual signals (clock, Serial triggering and analysis application data, chip enable, etc.) that make up your bus, making it easy to identify modules where packets begin and end and identifying subpacket components such On a serial bus, a single signal often includes address, control, data, and as address, data, identifier, CRC, etc. clock information. This can make isolating events of interest difficult. The Serial Application modules for the MDO/MSO/DPO4000B, MDO3 000, and MSO/DPO2000B Series transform the oscilloscopes into a robust tool for 2 debugging serial buses with automatic trigger, decode, and search for I C, 2 SPI, CAN, LIN, FlexRay, RS-232/422/485/UART, MIL-STD-1553, I S/LJ/ RJ/TDM, USB, and Ethernet. www.tektronix.com 1Datasheet Bus decoding 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 a Serial Application module do it for you Once youve set up a bus, the oscilloscope will decode each packet on the bus, and display the value in hex, binary, decimal (LIN, MIL-STD-1553, and 2 FlexRay, USB and Ethernet only), signed decimal (I S/LJ/RJ/TDM only), or ASCII (RS-232/422/485/UART, USB and Ethernet only) in the bus waveform. Event table showing decoded Identifier, DLC, DATA, and CRC for every CAN packet in a long acquisition Search Serial triggering is very useful for isolating the event of interest, but once youve 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 Serial Application module, you can enable the oscilloscope to automatically Color-coded display of a CAN bus, showing Start, DLC, Data, CRC, and Stop search through the acquired data for user-defined criteria including serial components of the serial signal. 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. The Search Mark table provides a tabular view of all events found during an automated search. The search mark data can be exported to a .csv file. Simultaneously display the bus and digital waveforms. Digital waveforms show how the bus translates the individual signals based on the threshold settings (useful for making analog channels look like just 1s and 0s). 2 Event table Search I C decode showing results from a Wave Inspector search for Address value 50. Wave Inspector controls provide unprecedented efficiency in viewing and navigating In addition to seeing decoded packet data on the bus waveform itself, you waveform data. 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 (Address, Data, etc.). 2 www.tektronix.com
