Digital phosphor technology with FastAcq
™
high-
speed waveform capture
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.
Digital phosphor technology provides you with fast insight into the real
operation of your device. Its fast waveform capture rate – greater than
280,000 wfms/s with FastAcq – gives you a high probability of quickly
seeing the infrequent problems common in digital systems: runt pulses,
glitches, timing issues, and more.
To further enhance the visibility of rarely occurring events, intensity grading
is used to indicate how often rare transients are occurring relative to normal
signal characteristics. There are four waveform palettes available in
FastAcq acquisition mode.
The
Temperature palette
uses color-grading to indicate frequency of
occurrence with hot colors like red/yellow indicating frequently
occurring events and colder colors like blue/green indicating rarely
occurring events.
The
Spectral palette
uses color-grading to indicate frequency of
occurrence with colder colors like blue indicating frequently occurring
events and hot colors like red indicating rarely occurring events.
The
Normal palette
uses the default channel color (like yellow for
channel one) along with gray-scale to indicate frequency of occurrence
where frequently occurring events are bright.
The
Inverted palette
uses the default channel color along with gray-
scale to indicate frequency of occurrence where rarely occurring events
are bright.
These color palettes quickly highlight the events that over time occur more
often or, in the case of infrequent anomalies, occur less often.
Infinite or variable persistence choices determine how long waveforms stay
on the display, helping you to determine how often an anomaly is occurring.

Mixed Domain Oscilloscopes -- MDO3000 Series
Digital phosphor technology with FastAcq enables greater than 280,000 wfms/s
waveform capture rate and real-time color-intensity grading.
Triggering
Discovering a device fault is only the first step. Next, you must capture the
event of interest to identify root cause. To enable this, the MDO3000
contains over 125 trigger combinations providing a complete set of triggers
- including runt, logic, pulse width/glitch, setup and hold violation, serial
packet, and parallel data - to help quickly locate your event of interest. And
with up to a 10 M 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.
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.
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.
Over 125 trigger combinations make capturing your event of interest easy.
Wave Inspector
®
waveform navigation and automated
search
With long record lengths, a single acquisition can include thousands of
screens of waveform data. Wave Inspector
®
, the industry’s best tool for
waveform navigation and automated search, enables you to find events of
interest in seconds.
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
Previous
(←) and
Next
(→) buttons. Search types include edge,
pulse width/glitch, timeout, runt, logic, setup and hold, rise/fall time, parallel
bus, and I

tabular view of the events found during the automated search. Each event
is shown with a time stamp, making timing measurements between events
easy.

Waveform analysis
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, waveform histograms, and trend plots for visually determining how
a measurement is changing over time.
Search step 1: You define what you would like to find.
Automated measurement readouts provide repeatable, statistical views of waveform
characteristics.
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.
Each measurement has help text and graphics associated with it that help explain how
the measurement is made.
Search step 3: The Search Mark table provides a tabular view of each of the events
found by the automated search. Each event is shown with a time stamp making timing
measurements between events easy.
Waveform histograms show visually how waveforms vary over time.
Horizontal waveform histograms are especially useful for gaining insight
into how much jitter is on a clock signal, and what the distribution of that
jitter is. Vertical histograms are especially useful for gaining insight into how
much noise is on a signal, and what the distribution of that noise is.
Measurements taken on a waveform histogram provide analytical
information about the distribution of a waveform histogram, providing
insight into just how broad a distribution is, the amount of standard
deviation, the mean value, etc.

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 fast waveform capture rate of the
MDO3000, 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.
Standard features such as IRE and mV graticules, holdoff by fields, video
polarity, HDTV and custom (nonstandard) video triggers, and an Autoset
smart enough to detect video signals, make these the easiest to use
oscilloscopes on the market for video applications. And with high
bandwidth, four analog inputs, and a built-in 75 Ω input termination (not
available on 1 GHz models), the oscilloscope provides ample performance
for analog and digital video use. There is even a video picture mode
enabling you to see the picture of the video signal you are viewing – for
NTSC and PAL signals.
Power analysis (optional)
Ever increasing consumer demands for longer battery-life devices and for
green solutions that consume less power require power-supply designers to
characterize and minimize switching losses to improve efficiency. In
addition, the supply’s power levels, output purity, and harmonic feedback
into the power line must be characterized to comply with national and
regional power quality standards. Historically, making these and many
other power measurements on an oscilloscope has been a long, manual,
and tedious process. The MDO3000’s optional power analysis tools greatly
simplify these tasks, enabling quick, repeatable and accurate analysis of
power quality, switching loss, harmonics, safe operating area (SOA),
modulation, ripple, and slew rate (di/dt, dv/dt). Completely integrated into
the oscilloscope, the power analysis tools provide automated, repeatable
power measurements with a touch of a button. The optional power analysis
functionality is offered free for a 30-day trial period. This free trial period
starts automatically when the instrument is powered on for the first time.
