Tektronix MDO3000 Series
Oscilloscope
Tektronix MDO3000 Mixed Domain Oscilloscope is the
ultimate integrated 6-in-1 oscilloscope that offers a spectrum
analyzer, arbitrary function generator (AFG), logic analyzer,
protocol analyzer, and digital voltmeter (DVM), enabling you to
quickly and cost effectively debug your designs.
Oscilloscope – At the core of the MDO3000 is the most
popular oscilloscope in this class.
100, 200, 350, 500 MHz and 1 GHz bandwidth models
Up to 5 GS/s sampling rate
10 Mpoint record length on every channel with Wave
Inspector®navigation and search controls
Up to a maximum waveform capture rate of >280,000
waveforms per second
More than 125 trigger combinations

Demonstration Guide

Spectrum Analyzer – Every MDO3000 ships standard with
a dedicated spectrum analyzer input which provides better
performance than a traditional oscilloscope FFT. The standard
integrated spectrum analyzer input frequency is from 9 kHz to
the bandwidth of the scope and is extendable to 3 GHz with
the MDO3SA option.
Arbitrary Function Generator (Optional) – Choose from 13
predefined standard waveforms like sine, square or ramp,
or replicate virtually any signal with the arbitrary waveform
generation with 128k record length and 250MS/s sample rate.
Even add noise to your waveform to perform margin testing
on your circuits.
Logic Analyzer (Optional) – The MDO3000 provides a 16
digital channel logic analyzer with the MDO3MSO option,
enabling you to look at multiple points in your design at once.
Protocol Analyzer (Optional) – The MDO3000 Series offers a
robust set of tools for debugging serial buses with automatic
trigger, decode, and search for I2C, SPI, CAN, LIN, FlexRay,
USB 2.0, RS-232, RS-422, RS-485, UART, USB 2.0, Mil-Std
1553.
Digital Voltmeter (DVM) (Optional) – For fast voltage and
frequency measurements, the optional digital voltmeter
is easy-to-use. The DVM is free when you register your
MDO3000 Series product.
Upgradability – The MDO3000 is completely upgradeable.
Upgrade scope bandwidth and RF input frequency, add
more functionality such as AFG, logic analyzer, and DVM,
or add analysis capability such as serial bus triggering and
decode, power measurement and limit/mask test, whenever
you need it.

Demonstration Guide

About This Guide
This demonstration guide takes you through a series of
step-by-step demonstrations on how the MDO3000 Series
oscilloscope helps simplify the debug of mixed signal designs
with its powerful functionality and integrated test instruments.
This oscilloscope can help you discover new ways to quickly
debug some of today’s most challenging and common design
problems.
Note: There are additional built-in product demos in
MDO3000. To explore other product demos and features,
press Utility front panel button, then press MDO3000 Utility
Page lower-bezel button and use Multipurpose a to select
Demo.
To go through the exercises, you need:
MDO demonstration board (includes a USB Y-cable used
to power the demo board) with waveforms that represent
a number of mixed-signal challenges facing today’s
designers. To find the desired signal on the demo board,
refer to the “Locating Signals” section at the end of this
demonstration guide.
BNC cable to connect AFG output to analog channel and
to connect to the spectrum analyzer input.
N-BNC adapter to connect BNC cable to RF input channel
(standard accessory)
Serial bus triggering and analysis application modules
DVM, AFG, Spectrum Analyzer options
Note: For demonstration purpose, all application modules
and options are enabled in MDO3000 demo units. They are
listed on the following page:

Demonstration Guide

Powering on the Board
To connect and power on the
demonstration board, follow these
steps:
1. Plug the dual USB A connectors from
one end of the “Y” USB cable, which
comes with your board, into two USB
ports of a PC or an oscilloscope. Do
this before plugging the single USB B
connector from the other end of the USB
cable into the demonstration board. You
need to attach both USB A connectors
to provide adequate power to the demo
board.
2. Plug the single B connector from the
other end of the USB cable into the demo
board. Two green and one red LEDs on
the board turn on and remain steady
when you apply adequate power to the
board. Figure 1.

Exercise 1
Capturing Elusive Events with FastAcq™
High Waveform Capture Rate
To debug a design problem, first you must know it exists.
The MDO3000 Series oscilloscope offers Tektronix proprietary
FastAcq™technology. It delivers a fast waveform capture –
up to 280,000 waveforms per second – that enables you to
see glitches and other infrequent transients within seconds,
revealing the true nature of device faults.
To further enhance the visibility of rarely occurring events,
intensity grading is used with multiple waveform palettes
to choose from, indicating how often rare transients are
occurring relative to normal signal characteristics. The
FastAcq waveform palettes are Temperature (color-grading
frequency of occurrence), Spectral (color-grading frequency
of occurrence), Normal (gray-scale where frequently occurring
events are bright) and Inverted (gray-scale where rare events
are bright).
This demo illustrates how FastAcq high waveform capture
rate can find anomalies quickly and display them with color-
grading. The demonstration looks for an erroneous runt signal
that occurs approximately every 838.8ms.
