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 virtually every-

where. They can contain many different

types of devices including microproces-

sors, microcontrollers, DSPs, RAM,

EEPROMs, FPGAs, ADCs, DACs, and

I/O. These various devices have tradi-

tionally 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 lower board space requirements,

fewer pins, lower power, embedded

clocks, differential signaling for better

noise immunity and most importantly,

lower cost. In addition, there’s a large

supply of off-the-shelf building block

components from reputable manufac-

turers, enabling rapid design development.

While serial buses have a large number

of benefits, they also present significant

challenges that their predecessors (parallel

buses) did not face.

They make debugging bus and system

problems more difficult, it’s harder to

isolate events of interest and it’s more

difficult to interpret what is displayed on

the oscilloscope screen. The MSO2000

and DPO2000 Series address these

challenges and represent the ultimate

tool for engineers working with serial

buses such as I

C, SPI, RS-232/422/

485/UART, CAN, and LIN.

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 popular serial inter-

faces - I

C, SPI, RS-232/422/485/UART,

CAN, and LIN.

Bus Decoding - Tired of having to

visually inspect the waveform to count

clocks and determine if each bit is a 1

or a 0, and then combine bits into bytes

and determine the hex value? Let the

oscilloscope 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 either hex, binary, decimal (LIN

only), or ASCII (RS-232/422/485/UART

only) in the bus waveform.

Event Table - In addition to seeing

decoded packet data on the bus wave-

form 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 consecu-

tively with columns for each component

(Address, Data, etc.). The event table

can also be exported for use offline.

Search - Serial triggering is very useful

for isolating an event of interest, but

once you’ve captured it and need to

analyze the surrounding data, what do

you do? In the past, you had to manually

scroll through the waveform, counting

and converting bits and looking for what

caused the event. With the MSO2000

and DPO2000 Series, you can have the

oscilloscope automatically search through

the acquired data for user-defined criteria

including serial packet content. Each

occurrence is marked for easy reference.

Rapid navigation between marks is as

simple as pressing the Previous

and Next buttons on the front panel.

Mixed Signal Design and Analysis

(MSO2000 Series)

As an embedded-design engineer, you

are faced with the challenge of ever-

increasing system complexity. A typical

embedded design may incorporate

various analog signals, high- and low-

speed serial digital communication and

microprocessor buses, just to name a

few. Serial protocols such as I

C and

SPI are used frequently for chip-to-chip

communication, but parallel buses are

still used in many applications.

MSO/DPO2000 triggered on a specific data

packet going across an I

C bus. No more counting

clock edges and 1s and 0s. A Bus waveform

provides decoded packet content including

Start, Address, Read/Write, Data, and Stop. And

the addition of timing waveforms makes it easy

to quickly determine values of two signals.
