Serial Triggering and Analysis
One of the most common applications
requiring long record length is serial
data analysis in embedded system
design. Embedded systems are literally
everywhere. They can contain many
different types of devices including
microprocessors, microcontrollers,
DSPs, RAM, EPROMs, FPGAs, A/Ds,
D/As and I/O. These various devices
have traditionally communicated with
each other and the outside world using
wide parallel buses. Today, however,
more and more embedded systems
are replacing these wide parallel buses
with serial buses due to less board
space required, fewer pins, lower
power, embedded clocks, differential
signaling for better noise immunity and
most importantly, lower cost. While
serial buses have a large number of
benefits, they also present significant
challenges that their predecessors
(parallel buses) did not. Debugging bus
and system problems can be more
difficult, because it is harder to isolate

Read/Write, Data and Stop.

events of interest and it is more difficult
to interpret what is displayed on the
oscilloscope screen. The DPO3000
Series addresses these problems.
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.
Serial Triggering – Trigger on packet
content such as start of packet,
specific addresses, specific data
content, unique identifiers, etc., on the
popular serial interfaces I
LIN and RS232/422/485/UART.
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 deter-
mine the hex value? Let the oscillo-
scope do it for you! The oscilloscope
can decode each packet on the bus
and display the value in hex, binary,
decimal, or ASCII (depending on the
standard) in the bus waveform.

Packet Decode 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 on a logic
analyzer. Packets are time-stamped
and listed consecutively with columns
for each component (Address, Data, etc.).
Search – 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 the DPO3000 Series, you can
have the oscilloscope 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
