Tektronix 4000 Series Digital Phosphor Oscilloscopes
The 4000 Series family includes the DPO4000 Series and the MSO4000
Series. The DPO4000 Series Digital Phosphor Oscilloscopes (DPOs) are the
first oscilloscopes to offer usable deep memory on all channels, excellent
performance, serial trigger and analysis options, and all in the most
compact form factor in their class. The MSO4000 Series Mixed Signal
Oscilloscopes (MSOs) provide all the features and benefits of the DPO4000,
but add 16 integrated digital channels, enabling you to visualize and
correlate analog and digital signals on a single instrument. This
integration extends triggering functionality across all 20 channels
providing pattern and state triggering ideal for debugging mixed analog and
digital designs.
Designed to Make Your Work Easier
As design complexity increases, you need tools that help you find
problems quickly.
Easy to Set-up and Use
The 4000 Series has a large 10.4 inch XGA display, a clean front panel
with familiar knobs - all in a package that is only 5.4” deep and weighs
only 11 lbs. With USB plug-and-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. Provided applications include
National Instruments SignalExpress™ Tektronix Edition, OpenChoice® Desktop
and Microsoft Excel and Word toolbars enabling fast and easy direct
communication with your Windows PC. USB and CompactFlash ports on the front
panel enable simple transfer of screenshots, instrument settings, and
waveform data in the palm of your hand. When it comes to mixed signal design
and debug, you want your instrument to be intuitive so you can start solving
problems quickly. The MSO4000 Series drives like an oscilloscope, the tool
you already know how to use. You do not have to relearn how to use the
instrument every time you turn it on.
Wave Inspector® Navigation
Imagine trying to efficiently use the Internet if search engines such as
Google and Yahoo didn’t exist, web browser features such as Favorites and
Links didn’t exist, or Internet Service Providers like AOL or MSN 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. Record
length, one of the key specifications of an oscilloscope, is the number of
samples it can digitize and store in a single acquisition. The longer the
record length, the longer the time window you can capture with high timing
resolution (high sample rate).
The first digital oscilloscopes could capture and store only 500 points,
which made it very difficult to acquire all relevant information around the
event being investigated. Over the years, oscilloscope vendors have provided
longer and longer record lengths to meet market demands for long capture
windows with high resolution, to the point that most mid-range oscilloscopes
either come standard with, or can be optionally upgraded to,
multi-mega-point record lengths. These mega-point record lengths often
represent thousands of screens worth of signal activity. While standard
record lengths have increased greatly over the years and can now satisfy the
vast majority of applications in the market-place, tools for effectively and
efficiently viewing, navigating and analyzing long record length
acquisitions have been sorely neglected until now.
The Tektronix 4000 Series redefines expectations for working with long
record lengths with the following innovative Wave Inspector controls:
Zoom/Pan - A dedicated, two-tier front-panel knob provides
intuitive control of both zooming and panning. The inner knob adjusts the
zoom factor (or zoom scale); turning it clockwise activates zoom and goes to
progressively higher zoom factors, while turning it counter-clockwise
results in lower zoom factors and eventually turning zoom off. The outer
knob pans the zoom box across the waveform to quickly get to the portion of
the waveform you are interested in. The outer knob also utilizes
force-feedback to determine how fast to pan on the waveform. The farther you
turn the outer knob, the faster the zoom box moves. Pan direction is changed
by simply turning the knob the other way. No longer do you need to navigate
through multiple menus to adjust your zoom view.
Play/Pause - A dedicated play/pause button on the front panel
scrolls the waveform across the display automatically while you look for
anomalies or an event of interest. Playback speed and direction are
controlled using the intuitive pan knob. Once again, turning the knob
further makes the waveform scroll faster and changing direction is as simple
as turning the knob the other way.
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 - Don’t want to take the time to inspect the entire
acquisition to find the event you’re looking for? The 4000 Series features a
robust waveform search feature that 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, RS-232 and CAN packet content.
Wave Inspector® controls provide unprecedented efficiency in viewing,
navigating and analyzing waveform data.

P6516 Mixed Signal Oscilloscope probe.
P6516 MSO Probe
This unique probe design offers two eight-channel pods. Each channel ends
with a new probe tip design that includes a recessed ground for simplified
connection to the device-under-test. This sleek new probe simplifies the
process of connecting to the device-under-test. The coax on the first
channel of each pod is colored blue making it easy to identify. The common
ground uses an automotive style connector making it easy to create custom
grounds for connecting to the device-under-test. When connecting to square
pins, the P6516 has an adapter that attaches to the probe head extending the
probe ground flush with the probe tip so you can attach to a header. The
P6516 offers outstanding electrical characteristics applying only 3 pF of
loading.
The Power to Solve Problems Quickly
The Performance and Feature Set You Expect
The 4000 Series Digital Phosphor Oscilloscopes (DPO) deliver the
performance you need to visualize even your most demanding signals.
Bandwidths range from 350 MHz to 1 GHz, and with all models offering a
minimum of 5x over-sampling on all channels and sin(x)/x interpolation
standard, you can be confident that even the fastest transient events will
be captured and displayed accurately. The standard 10M record length on all
channels enables you to capture long windows of signal activity while
maintaining fine timing resolution.
The 4000 Series offers a variety of analytical solutions including
cursors, 25 automatic measurements, statistics and waveform math. Despite a
tiny footprint (only 5.4 in. deep) and lightweight (11 lbs.), the 4000
Series offers exceptional performance, a large 10.4" XGA display and
knob-per-channel vertical controls.
The 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 itself. 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.
MagniVu™
The main digital acquisition mode on the MSO4000 Series will capture up
to 10 M points at 500 MS/s (2 ns resolution). In addition to the main
record, the MSO4000 provides an ultra high resolution mode called MagniVu
which acquires 10,000 points at up to 16.5 GS/s (60.6 ps resolution). Both
main and MagniVu waveforms are acquired on every trigger and can be switched
between at any time, running or stopped. MagniVu provides close to ten times
finer timing resolution than any other MSO on the market, instilling
confidence when making critical timing measurements on digital waveforms.

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, ADCs,
DACs 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 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 manufacturers,
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 4000 Series addresses
these challenges and represents the ultimate tool for engineers working with
low-speed serial buses such as I2C, SPI, RS-232 and CAN.
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 low-speed serial interfaces such as I2C, SPI, RS-232
and CAN.
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 oscilloscope will decode each packet on the bus, and
display the value in either hex, binary or ASCII (RS-232 only) in the bus
waveform.
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 on a logic analyzer. Packets are 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, you had to manually scroll through the
waveform, counting and converting bits and looking for what caused the
event. With the 4000 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 Prev and Next buttons on the front panel.

Mixed Signal Design and Analysis (MSO4000)
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 I2C
and SPI are used frequently for chip-to-chip communication, but parallel
buses are still used in many applications. Microprocessors, FPGAs,
Analog-to-Digital Converters (ADCs), and Digital-to-Analog Converters (DACs)
are all examples of ICs that present unique measurement challenges in
today’s embedded designs. The MSO4000 Series Mixed Signal Oscilloscopes
offer the addition of 16 digital channels. These channels are tightly
integrated into the oscilloscope's user interface, simplifying operation and
making it possible to solve mixed signal issues more easily.
Next Generation Digital Waveform Display
In a continued effort to make mixed signal oscilloscopes easy to use, the
MSO4000 Series has redefined the way you view digital waveforms. One common
problem shared by both logic analyzers and mixed signal oscilloscopes is
determining if data is a one or a zero when zoomed in far enough that the
digital trace stays flat all the way across the display. The MSO4000 has
color-coded the digital traces, displaying ones in green and zeros in blue.
The MSO4000 has multiple transition detection hardware. When the system
detects multiple transitions, the user will see a white edge on the display.
White edges indicate that more information is available by zooming in or
acquiring at faster sampling rates. In most cases zooming in will reveal the
pulse that was not viewable at the previous settings. If the white edge is
still present after zooming in as far as possible, this indicates that
increasing your sample rate on the next acquisition will reveal higher
frequency information than your previous settings could acquire.
White edges indicate additional information is available by zooming
in.
Channel setup on an MSO can often be time-consuming as compared to the
traditional oscilloscope. This process often includes probing the
device-under-test, labeling the channels and positioning the channels on
screen. The MSO4000 simplifies this process by allowing the user to group
digital waveforms. By simply placing digital waveforms next to each other,
they form a group. Once a group is formed, you can position all the channels
contained in that group together. This greatly reduces the normal setup time
associated with positioning channels individually.
Groups are created by simply placing digital channels together on the
screen. You can position and set threshold values for a group in a single
step.

Other Applications
Video Design and Development
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 4000 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 analog inputs, the 4000 Series provides ample performance for
analog and digital video use.
