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.
A complete set of triggers - including runt, timeout, logic, pulse width/glitch,
setup/hold violation, serial packet, and parallel data - help you quickly find
your event. With up to a 20M point 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 oscilloscope provides integrated support for the industry's
broadest range of serial buses - I
2
C, SPI, USB, Ethernet, CAN, LIN,
FlexRay, RS-232/422/485/UART, MIL-STD-1553, and I
2
S/LJ/RJ/TDM. The
ability to decode up to four 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 on these channels enables you to acquire fine signal
detail (up to 60.6 ps resolution) around the trigger point for precision timing
measurements. MagniVu is essential for making accurate timing
measurements for setup and hold, clock delay, signal skew, and glitch
characterization.
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.
Discover
‒
Fast waveform capture rate - over 50,000 wfm/s - maximizes the probability
of capturing elusive glitches and other infrequent events.
Capture
Discovering a device fault is only the first step. Next, you must capture the
event of interest to identify root cause.
Accurately capturing any signal of interest begins with proper probing. Low-
capacitance probes are included with the oscilloscope, one for each analog
channel. These industry-first high-impedance passive voltage probes have
less than 4 pF of capacitive loading to minimize the affect of the probe on
your circuit's operation, offering the performance of an active probe with the
flexibility of a passive probe.
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.

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.
The innovative Wave Inspector
®
controls give you the industry’s most
comprehensive search and waveform navigation capability. These controls
speed panning and zooming through your record. With a unique force-
feedback system, you can move from one end of your record to the other in
just seconds. User marks allow you to mark any location that you may want
to reference later for further investigation. Or, automatically search your
record for criteria you define. Wave Inspector will instantly search your
entire record, including analog, digital, and serial bus data. Along the way it
will automatically mark every occurrence of your defined event so you can
quickly move between events.
Analyze – Waveform histogram of a falling edge showing the distribution of edge position

acquisition looking for user-defined events. All occurrences of the event are
highlighted with search marks and are easily navigated to, using the front-

S/LJ/RJ/TDM packet content.
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.
Search step 1: You define what you would like to find.
Play/Pause
A dedicated
Play/Pause
front-panel button 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 control.
Once again, turning the control further makes the waveform scroll faster
and changing direction is as simple as turning the control the other way.
User marks
Press the
Set Mark
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 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.
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.
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.
Digital phosphor technology enables greater than 50,000 wfms/s waveform capture rate
and real-time intensity grading.
Accurate high-speed probing
The TPP Series probes, included standard with every MSO/DPO4000B
Series oscilloscope, provide up to 1 GHz of analog bandwidth, and less
than 4 pF of capacitive loading. The extremely low capacitive loading
minimizes adverse affects on your circuits and is more forgiving of longer
ground leads. And, since the probe bandwidth matches or exceeds your
oscilloscope bandwidth, you can see the high-frequency components in
your signal which is critical for high-speed applications. The TPP Series
passive voltage probes offer all the benefits of general-purpose probes like
high dynamic range, flexible connection options, and robust mechanical
design, while providing the performance of active probes. In addition, a low-
attenuation, 2X version of the TPP probes is available for measuring low
voltages. Unlike other low-attenuation passive probes, the TPP0502 has
high bandwidth (500 MHz) as well as low capacitive loading (12.7 pF).
