Mixed Signal Oscilloscopes — MSO4000B, DPO4000B Series
Serial triggering
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, USB, Ethernet, CAN, LIN, FlexRay, RS-232/422/485/
UART, MIL-STD-1553, and I2S/LJ/RJ/TDM.
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.
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 do it for you! Once you've set up a bus, the
MSO/DPO4000B Series will decode each packet on the bus, and display
the value in hex, binary, decimal (USB, Ethernet, MIL-STD-1553, LIN, and
FlexRay only), signed decimal (I2S/LJ/RJ/TDM only), or ASCII (USB,
Ethernet, and RS-232/422/485/UART only) in the bus waveform.
The P6616 MSO probe offers two eight-channel pods to simplify connecting to your
device.
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 (Address, Data, etc.). You can save the event
table data in .csv format.
Serial triggering and analysis (optional)
On a serial bus, a single signal often includes address, control, data, and
clock information. This can make isolating events of interest difficult.
Automatic trigger, decode, and search on bus events and conditions gives
you a robust set of tools for debugging serial buses.

waveform is the D+ and the blue waveform is the D-. A bus waveform provides decoded
packet content including Start, Sync, PID, Address, End Point, CRC, Data values, and
Stop.
