Feature-rich tools for debugging mixed
signal designs
With Wave Inspector
®
controls for rapid waveform navigation, automated
serial and parallel bus analysis, and automated power analysis – your
Tektronix oscilloscope provides the feature-rich tools you need to simplify
and speed debug of your complex design.
Capture
Discovering a device fault is only the first step. Next, you must capture the
event of interest to identify root cause.
The MSO/DPO3000 Series provides a complete set of triggers – including
runt, logic, pulse width/glitch, setup/hold violation, serial packet, and
parallel data – to help quickly find your event. With up to a 5 Mpoint record
length, you can capture many events of interest, even thousands of serial
packets, in a single acquisition for further analysis while maintaining high
resolution to zoom in on fine signal details.
From triggering on specific packet content to automatic decode in multiple
data formats, the MSO/DPO3000 Series provides integrated support for the
industry’s broadest range of serial buses – I
2
C, SPI, MIL-STD-1553, CAN,
LIN, FlexRay, RS-232/422/485/UART, and I
2
S/LJ/RJ/TDM. The ability to
decode up to two serial and/or parallel buses simultaneously means you
gain insight into system-level problems quickly.
To further help troubleshoot system-level interactions in complex
embedded systems, the oscilloscope 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 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.
Comprehensive features speed every stage
of debug
These oscilloscopes offer a robust set of features to speed every stage of
debugging your design – from quickly discovering an anomaly and
capturing it, to searching your waveform record for the event and analyzing
its characteristics and your device’s behavior.
Discover
To debug a design problem, first you must know it exists. Every design
engineer spends time looking for problems in their design, a time-
consuming and frustrating task without the right debug tools.
The industry’s most complete visualization of signals provides fast insight
into the real operation of your device. A fast waveform capture rate –
greater than 50,000 waveforms per second – enables you to see glitches
and other infrequent transients within seconds, revealing the true nature of
device faults. A digital phosphor display with intensity grading shows the
history of a signal’s activity by intensifying areas of the signal that occur
more frequently, providing a visual display of just how often anomalies
occur.
Capture
‒
Triggering on a specific transmit data packet going across an RS-232 bus. A
complete set of triggers, including triggers for specific serial packet content, ensures you
quickly capture your event of interest.
Discover
‒
Fast waveform capture rate - over 50,000 wfm/s - maximizes the probability
of capturing elusive glitches and other infrequent events.
Search
Finding your event of interest in a long waveform record can be time
consuming without the right search tools. With today’s record lengths
pushing beyond a million data points, locating your event can mean
scrolling through thousands of screens of signal activity.

Analyze
Verifying that your prototype’s performance matches simulations and meets
the project’s design goals requires analyzing its behavior. Tasks can range
from simple checks of rise times and pulse widths to sophisticated power
loss analysis and investigation of noise sources.
The oscilloscope offers a comprehensive set of integrated analysis tools
including waveform- and screen-based cursors, automated measurements,
advanced waveform math including arbitrary equation editing, FFT
analysis, and trend plots for visually determining how a measurement is
changing over time. Specialized application support for serial bus analysis,
power supply design, and video design and development is also available.
For extended analysis, National Instrument’s LabVIEW SignalExpress
®
Tektronix Edition provides over 200 built-in functions including time and
frequency domain analysis, limit testing, data logging, and customizable
reports.
Wave Inspector controls provide unprecedented efficiency in viewing, navigating, and
analyzing waveform data. Zip through your long record by turning the outer pan control
(1). Get details from the beginning to end in seconds. See something of interest and want
to see more details? Just turn the inner zoom control (2).
Zoom and pan
A dedicated, two-tier front-panel control provides intuitive control of both
zooming and panning. The inner control adjusts the zoom factor (or zoom
scale); turning it clockwise activates zoom and goes to progressively higher
zoom factors, while turning it counterclockwise results in lower zoom
factors and eventually turning zoom off. No longer do you need to navigate
through multiple menus to adjust your zoom view. The outer control pans
the zoom box across the waveform to quickly get to the portion of waveform
you are interested in. The outer control also utilizes force-feedback to
determine how fast to pan on the waveform. The farther you turn the outer
control, the faster the zoom box moves. Pan direction is changed by simply
turning the control the other way.

front-panel button to place one or more marks on the
waveform. Navigating between marks is as simple as pressing the
Previous
(←) and
Next
(→) buttons on the front panel.
Search marks
The
Search
button allows you to automatically search through your long
acquisition looking for user-defined events. All occurrences of the event are
highlighted with search marks and are easily navigated to, using the front-
panel

Search step 2: Wave Inspector automatically searches through the record and marks
each event with a hollow white triangle. You can then use the Previous and Next buttons
to jump from one event to the next.
Digital phosphor technology
Digital phosphor technology provides you with fast insight into the real
operation of your device. Its fast waveform capture rate – greater than
50,000 wfm/s – gives you a high probability of quickly seeing the infrequent
problems common in digital systems: runt pulses, glitches, timing issues,
and more.
Waveforms are superimposed with one another and waveform points that
occur more frequently are intensified. This quickly highlights the events that
over time occur more often or, in the case of infrequent anomalies, occur
less often.
You can choose infinite persistence or variable persistence, determining
how long the previous waveform acquisitions stay on-screen. This allows
you to determine how often an anomaly is occurring.
Search step 1: You define what you would like to find.
Digital phosphor technology enables greater than 50,000 wfms/s waveform capture rate
and real-time intensity grading.

MSO3000 Series and DPO3000 Series Mixed Signal Oscilloscopes
Mixed signal design and analysis (MSO
series)
The MSO models provide 16 digital channels which are tightly integrated
into the oscilloscope's user interface. This simplifies operation and makes it
possible to solve mixed-signal issues easily.
White edges indicate additional information is available by zooming in. As shown here,
zooming in on the white edge reveals a hidden glitch.
You can group digital waveforms and enter waveform labels by using a
USB keyboard. By simply placing digital waveforms next to each other, they
form a group.
The MSO Series provides 16 integrated digital channels enabling you to view and
analyze time-correlated analog and digital signals.
Color-coded digital waveform display
This oscilloscope 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. Color-
coded digital traces display ones in green and zeros in blue.
The multiple transition detection hardware shows you a white edge on the
display when the system detects multiple transitions. 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 with the previous settings. If the white edge is still present after
zooming in as far as possible, this indicates that increasing the sample rate
on the next acquisition will reveal higher frequency information than the
previous settings could acquire.
With color-coded digital waveform display, groups are created by simply placing digital
channels together on the screen, allowing digital channels to be moved as a group. You
can set threshold values for each channel, enabling support for up to 16 different logic
families.
Once a group is formed, you can position all the channels contained in that
group collectively. This greatly reduces the normal setup time associated
with positioning channels individually.
