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
MDO4000, MSO/DPO4000, MSO/DPO3000, and MSO/DPO2000 Series transform
the oscilloscopes 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, and I2S/LJ/RJ/TDM.
Serial Triggering
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.
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, MIL-STD-1553, and I2S/LJ/RJ/TDM.
Bus Display
Color-coded display of
a CAN bus, showing Start, DLC, Data, CRC, and Stop components of the
serial signal.
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).
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 subpacket
components such as address, data, identifier, CRC, etc.
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 MDO4000, MSO/DPO4000, MSO/DPO3000, or MSO/DPO2000 Series will
decode each packet on the bus, and display the value in hex, binary,
decimal (LIN, MIL-STD-1553, and FlexRay only), signed decimal (I2S/LJ/RJ/TDM only), or ASCII (RS-232/422/485/UART only) in
the bus waveform.
Event Table
Event table
showing decoded Identifier, DLC, DATA, and CRC for every CAN packet
in a long acquisition.
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 (Address, Data, etc.).

Serial 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 Serial Application module, you can enable the MDO4000, MSO/DPO4000,
MSO/DPO3000, and MSO/DPO2000 Series oscilloscopes 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.
