to simplify and speed debug of your complex design.

Data Sheet

Discover – A waveform capture rate of 5,000 wfm/s maximizes the probability of capturing

elusive glitches and other infrequent events.

Comprehensive Features Speed Every Stage

of Debug

The MSO/DPO2000 Series offers 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 MSO/DPO2000 Series offers complete visualization of signals,

providing fast insight into the real operation of your device. A waveform

capture rate of 5,000 waveforms per second enables you to see glitches

and other infrequent transients quickly, 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.

Capture

Discovering a device fault is only the ﬁrst step. Next, you must capture the

event of interest to identify root cause.

The MSO/DPO2000 Series provides a complete set of triggers – including

runt, logic, pulse width/glitch, setup/hold violation, serial packet, and parallel

data–tohe

lp quickly ﬁnd your event. With up to a 1 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/DPO2000 Series provides integrated

support for a broad range of serial buses – I2C,SPI,CAN,LIN,and

RS-232/422/485/UART. 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 MSO2000 Series 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.

Search–I

2C decode showing results from a Wave Inspector search for Address value

50. Wave Inspector controls provide unprecedented efﬁciency in viewing and navigating

waveform data.

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 to a million data points, locating your event can mean scrolling

through thousands of screens of signal activity.

The MSO/DPO2000 Series offers the industry’s most comprehensive

search and waveform navigation with its innovative Wave Inspector®

controls. 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 – FFT analysis of a pulsed signal. A comprehensive set of integrated analysis

tools speeds veriﬁcation of your design’s performance.

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 MSO/DPO2000 Series offers a comprehensive set of integrated

analysis tools including waveform- and screen-based cursors, 29

automated measurements, and FFT analysis. Specialized application

support for serial bus analysis 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.

Data Sheet

Wave Inspector controls provide unprecedented efﬁciency in viewing, navigating, and

analyzing waveform data. Zip through your 1 Mpoint record by turning the outer pan

control (1). Get from the beginning to end in seconds. See something of interest and want

to see more details? Just turn the inner zoom control (2).

Wave Inspector®Navigation and Search

A 1 Mpoint record length represents thousands of screens of information.

The MSO/DPO2000 Series enables you to ﬁnd your event in seconds with

Wave Inspector, the industry’s best tool for navigation and search.

Wave Inspector offers the following innovative controls:

Zoom/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.

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.

Search step 1: You deﬁne what you would like to ﬁnd.

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.

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 (←)andNext (→) buttons on the front panel.

Search Marks

The Searchbutton 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, runt, logic, setup and hold, rise/fall time parallel

bus, and I2C, SPI, CAN, LIN, and RS-232/422/485/UART packet content.

Mixed Signal Oscilloscopes — MSO2000 Series, DPO2000 Series

Digital phosphor technology enables a 5,000 wfm/s waveform capture rate and real-time

intensity grading on the MSO/DPO2000 Series.

The MSO Series provides 16 integrated digital channels enabling you to view and analyze

time-correlated analog and digital signals.

Digital Phosphor Technology

The MSO/DPO2000 Series’ digital phosphor technology provides you with

fast insight into the real operation of your device. Its waveform capture rate

of 5,000 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

With the color-coded digital waveform display, groups are created by simply placing digital

channels together on the screen, allowing the digital channels to be moved as a group.

You can set threshold values for each pod of eight channels, enabling support for up to

two different logic families.

that over time occur more often or, in the case of infrequent anomalies,

occur less often.

With the MSO/DPO2000 Series, 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 MSO2000 Series Mixed Signal Oscilloscopes provide 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 easily.

Color-coded Digital Waveform Display

The MSO2000 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

MSO2000 Series has color-coded digital traces, displaying ones in green

and zerosinblue.

Data Sheet

White edges indicate additional information is available by acquiring at a higher sample

rate.

The P6316 MSO probe offers two eight-channel pods to simplify connecting to your

device.

The multiple transition detection hardware of the MSO2000 Series will

show you a white edge on the display when the system detects multiple

transitions. This acts as a visual reminder that increasing the sample rate

on the next acquisition will reveal higher frequency information than your

previous settings could acquire.

The MSO2000 Series simpliﬁes channel setup by allowing you to 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.

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.

P6316 MSO Probe

This unique probe design offers two eight-channel pods, simplifying the

process of connecting to the device-under-test. When connecting to square

pins, the P6316 can connect directly to 8×2 square pin headers spaced

on tenth-inch centers. When more attachment ﬂexibility is required, you

can use the included ﬂying lead sets and grabbers to clip onto surface

mount devices or test points. The P6316 offers outstanding electrical

characteristics applying only 8 pF of capacitive loading with 101 kΩinput

impedance.

Output of DAC Signal – Notice how FilterVu™ clearly shows the noise-free steps of the

DAC in the foreground trace (yellow) which has removed all frequencies above 5.5 kHz.

FilterVu also captures and displays high-frequency glitches up to the full bandwidth of the

oscilloscope in the background trace (orange).

FilterVu™ Variable Low-pass Filter

Tired of being limited to a 20 MHz bandwidth ﬁlter in your oscilloscope?

Simply turn on FilterVu and adjust the variable low-pass noise ﬁlter. Unlike

other variable low-pass ﬁlters, FilterVu ﬁlters out the unwanted noise from

your signal while still capturing glitches and other signal details up to the full

bandwidth of the oscilloscope. It does this by showing two waveforms: a

waveform that can be ﬁltered (foreground waveform) and a glitch capture

waveform (background waveform).

The ﬁltered waveform uses a variable low-pass ﬁlter to block out noise,

yielding a cleaner waveform to more precisely locate signal edges

and amplitude levels. The result is improved conﬁdence in you cursor

measurements and cleaner documentation of important signal attributes.

When the noise ﬁlter is adjusted to the lowest available noise-cutoff

frequency, no more than 1% of high-frequency content that could cause the

oscilloscope to alias will pass through the ﬁlter.

The glitch capture waveform shows signal details up to the full bandwidth of

the oscilloscope. The oscilloscope captures pulses as narrow as 5 ns, using

peak-detect min/max sampling, protecting you from missing unexpected

glitches or other high-frequency events.

FilterVu is ideal for repetitive, nonrepetitive, and single-shot events.

Mixed Signal Oscilloscopes — MSO2000 Series, DPO2000 Series

Triggering on a speciﬁc data packet going across an I2C bus. The yellow waveform is

clock and the blue waveform is data. A bus waveform provides decoded packet content

including Start, Address, Read/Write, Data, and Stop.

Serial Triggering and Analysis (Optional)

On a serial bus, a single signal often includes address, control, data, and

clock information. This can make isolating events of interest difﬁcult. The

MSO/DPO2000 Series offers a robust set of tools for debugging serial

buses with automatic trigger, decode, and search for I2C, SPI, CAN, LIN,

and RS-232/422/485/UART.

Serial Triggering

Trigger on packet content such as start of packet, speciﬁc addresses,

speciﬁc data content, unique identiﬁers, etc. on popular serial interfaces

such as I2C, SPI, CAN, LIN, and RS-232/422/485/UART.

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 subpacket components such as

address, data, identiﬁer, CRC, etc.

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

Event table showing decoded Identiﬁer, DLC, DATA, and CRC for every CAN packet in

alongacquisition.

MSO/DPO2000 Series will decode each packet on the bus, and display the

value in hex, binary, decimal (LIN only), or ASCII (RS-232/422/485/UART

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 in

a software listing. Packets are time stamped and listed consecutively with

columns for each component (Address, Data, etc.).

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, users had to manually scroll through the waveform

counting and converting bits and looking for what caused the event. With

the MSO/DPO2000 Series, you can have the oscilloscope automatically

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 Previous (←)and

Next (→)buttons on the front panel.
