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
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,
Serial Triggering – Trigger on packet
content such as start of packet,
specific addresses, specific data
content, unique identifiers, etc., on the
popular serial interfaces I2C, SPI, CAN,
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 determine the hex value? Let the
oscilloscope 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
Previous and Next buttons
on the front panel.
- Mixed Signal Oscilloscopes (MSO Models)
To further help troubleshoot system-level
interactions in complex embedded systems, the MSO3000 Series offers 16
digital channels in addition to its analog channels. Since the digital
channels are fully integrated into the oscilloscope, you can trigger
across all input channels, automatically time-correlating all analog,
digital, and serial signals. The MagniVu™ high-speed acquisition enables
you to acquire fine signal detail (up to 121.2 ps resolution) around the
trigger point for precision measurements. MagniVu is essential for
making accurate timing measurements for setup and hold measurements,
clock delay, signal skew, and glitch characterization.
Wave Inspector Navigation
Imagine trying to efficiently use the internet if
search engines didn't exist, web browser features such as favorites
didn't exist or ISPs weren't around. Now you know how most modern
oscilloscope users feel when trying to actually use the long record
length in their digital oscilloscope. The longer the record length, the
longer the time window you can capture with high resolution (high sample
rate). Megapoint record lengths represent thousands of screens worth of
signal activity. Tools for effectively and efficiently viewing,
navigating and analyzing long record length acquisitions have been
sorely neglected until now.
The 4000 Series redefines expectations for working
with long record lengths with these innovative Wave Inspector controls:
Zoom/Pan. A dedicated, two-tier knob
provides intuitive control of both zooming and panning. The inner knob
adjusts zoom factor or scale. The outer knob pans the zoom box across
the waveform. The farther you turn the outer knob, the faster the zoom
box moves. No longer do you need to navigate through multiple menus to
adjust your zoom view.
Play/Pause. A dedicated play/pause button
scrolls the waveform automatically while you look for anomalies or an
event of interest. Playback speed and direction are controlled using the
intuitive pan knob.
User Marks. See something interesting on
your waveform? Press the Set Mark button on the front panel to leave one
or more "bookmarks" on the waveform. Navigating between marks is as
simple as pressing the Previous and Next buttons on the front panel.
Search Marks. A robust waveform search
feature allows you to search through your long acquisition based on
user-defined criteria. All occurrences of the event are highlighted with
search marks and are easily navigated to, using the front panel Previous
and Next buttons. Search types include edge, pulse width, runt, logic,
setup and hold, rise/fall time and I2C, SPI and CAN packet content.
Automotive Serial Triggering and Analysis Module. Enables triggering on
packet level information on CAN bus and LIN bus as well as analytical tools such as
digital views of the signal, bus views, packet decoding, search tools
and packet decode tables with timestamp information.
Embedded Serial Triggering and Analysis Module. Enables triggering on
packet level information on I2C and SPI buses as well as analytical
tools such as digital views of the signal, bus views, packet decoding,
search tools and packet decode tables with timestamp information. SPI is
available on four-channel models only.
Computer Serial Triggering and Analysis Module. Enables
triggering on packet level information on RS-232/422/485/UART buses as
well as analytical tools such as digital views of the signal, bus views,
packet decoding, search tools and packet
decode tables with timestamp information.

TekVPI - The New Standard for Ease of
The new TekVPI™ probe interface sets the
standard for ease of use in probing. TekVPI probes feature status
indicators and controls, as well as a probe menu button right on the
comp box. This button brings up a probe menu on the oscilloscope display
with all relevant settings and controls for the probe.
The TekVPI interface utilizes a new probe
power management architecture enabling direct attachment of current
probes without requiring a separate, bulky power supply. Finally, TekVPI
probes can be controlled remotely via USB, GPIB or Ethernet, enabling
more versatile solutions in ATE environments.
Unprecedented USB Connectivity
The DPO3000 Series delivers an unprecedented
new level of USB plug n play operation and PC connectivity. Acquiring
data and measurements from the instrument is as simple as connecting a
USB cable from the oscilloscope to the PC.

Digital Design and Debug Applications
The interoperability of the DPO3000 Series
oscilloscope with the Tektronix TLA5000 Series logic analyzer made
possible by Tektronix’ Integrated View (iView™) feature enables digital
designers to solve signal integrity challenges and effectively debug and
verify their systems more quickly and easily.
The iView feature fully integrates the
industry-leading performance and measurement accuracy of a Tektronix
oscilloscope with the multi-channel and powerful triggering capabilities
of a Tektronix logic analyzer. This integration allows designers to view
time-correlated digital and analogue data in
the same display window, and isolate analog characteristics of digital
signals that are causing failures in their systems.
The iView Wizard feature simplifies this
integration of the oscilloscope and logic analyzer by guiding the user
through set up and connection. No user calibration is required. And,
once set up, the iView feature is completely automated. The result - an
integrated tool set for digital design and troubleshooting. (Requires
iView cable and Tek-USB-488 converter).
Video Design and Development Applications
Many video engineers have remained loyal to
analog oscilloscopes, believing the intensity gradations on an analog
display are the only way to see certain video waveform details.
The DPO3000 Series' fast waveform capture
rate coupled with its intensity graded view of the signal provides the
same information-rich display as an analog oscilloscope, but with much
more detail and all the benefits of digital scopes. With up to 1 GHz
bandwidth and four inputs, the DPO3000 family provides ample performance
for analog and digital video use.
