Serial Triggering and Analysis Application Modules AERO • AUDIO • AUTO • AUTOMAX • COMP • EMBD • FLEX • USB • ENET Datasheet Key features Automated Serial Triggering, Decode, and Search options for I2C, SPI, CAN, LIN, FlexRay, RS-232/422/485/UART, MIL-STD-1553, I2S/LJ/ RJ/T DM, USB, and Ethernet. Trigger on all the critical elements of a serial bus such as address, data, etc. Decode all the critical elements of each message. No more counting 1s and 0s! Triggering on a specific transmit data packet going across an RS-232 bus. A complete set of triggers, including triggers for specific serial packet content, ensures you quickly 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 events found during an automated search. Serial triggering Export Search Mark table data to .csv file. Event table shows decoded serial bus activity in a tabular, timestamped format for quick summary of system activity. Export Event table data to .csv file. Serial triggering and analysis application modules On a serial bus, a single signal often includes address, control, data, and clock information. This can make isolating events of interest difficult. The Serial Application modules for the MDO4000C, MDO3000, and MSO/ DPO2000B Series transform the oscilloscope into a robust tool for debugging serial buses with automatic trigger, decode, and search for I2C, SPI, CAN, LIN, FlexRay, RS-232/422/485/UART, MIL-STD-1553, I2S/LJ/ RJ/TDM, USB2, and Ethernet. Trigger on packet content such as start of packet, specific addresses, specific data content, unique identifiers, etc. on popular serial interfaces such as I2C, SPI, CAN, LIN, FlexRay, RS-232/422/485/UART, MILSTD-1553, and I2S/LJ/RJ/TDM, USB2, and Ethernet. Bus display Provides a higher-level, combined view of the individual signals (clock, data, chip enable, etc.) that make up your bus, making it easy to identify where packets begin and end and identifying sub-packet components such as address, data, identifier, CRC, etc.

Datasheet 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 you’ve 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 FlexRay, USB and Ethernet only), signed decimal (I2S/LJ/RJ/TDM only), or ASCII (RS-232/422/485/UART, USB and Ethernet only) in the bus waveform.
