Features

PatternLock Triggering

The Enhanced Trigger Option (Option 001) on the 86100C

provides a fundamental capability never available

before in an equivalent time sampling oscilloscope.

This new triggering mechanism enables the DCA-J to

generate a trigger at the repetition of the input data

pattern – a pattern trigger. Historically, this capability

required the pattern source to provide this type of

trigger output to the scope. PatternLock automatically

detects the pattern length, data rate and clock rate

making the complex triggering mechanism transparent

to the user.

PatternLock enables the 86100C to behave more like a

real-time oscilloscope in terms of user experience.

Investigation of specific bits within the data pattern is

greatly simplified. Users that are familiar with real-time

oscilloscopes, but perhaps less so with equivalent time

sampling scopes will be able to ramp up quickly.

PatternLock adds another new dimension to pattern

triggering by enabling the mainframe software to take

samples at specific locations in the data pattern with

outstanding timebase accuracy. This capability is a

building block for many of the new capabilities available

in the 86100C described later.

Four Instruments in One

The 86100C Infiniium DCA-J can be viewed as four

high-powered instruments in one:

• A general-purpose wide-bandwidth sampling

oscilloscope; the new PatternLock triggering

significantly enhances the usability as a general

purpose scope

• A digital communications analyzer; the new

Eyeline Mode feature adds a powerful new tool to eye

diagram analysis

• A time domain reflectometer

• A jitter analyzer

Just select the instrument mode and start making

measurements.

Configurable to meet your needs

The 86100C supports a wide range of plug-ins for testing

both optical and electrical signals. Select plug-ins to get

the specific bandwidth, filtering, and sensitivity you need.

Jitter Analysis

The “J” in DCA-J represents jitter analysis. The 86100C

is a Digital Communications Analyzer with Jitter

analysis capability. The 86100C adds a fourth mode

of operation – Jitter Mode.

As data rates increase in both electrical and optical

applications, jitter is an ever increasing measurement

challenge. Decomposition of jitter into its constituent

components is becoming more critical. It provides

critical insight for jitter budgeting and performance

optimization in device and system designs. Many

emerging standards require jitter decomposition for

compliance. Traditionally, techniques for separation of

jitter have been complex and often difficult to configure,

and availability of instruments for separation of jitter

becomes very limited as data rates increase.

The DCA-J provides simple, one button setup and

execution of advanced waveform analysis. Jitter Mode

decomposes jitter into its constituent components and

presents jitter data in various insightful displays. Jitter

Mode operates at all data rates the 86100C supports,

removing the traditional data rate limitations from

complex jitter analysis. The 86100C brings several

key attributes to jitter analysis:

• Very low intrinsic jitter (both random and

deterministic) translates to a very low jitter noise

floor which provides unmatched jitter measurement

sensitivity.

• Wide bandwidth measurement channels deliver very

low intrinsic data dependent jitter and allow analysis

of jitter on all data rates up to 40 Gb/s and beyond.

• PatternLock triggering technology provides sampling

efficiency that makes jitter measurements very fast.

Jitter analysis functionality is segmented into two

software package options. Option 100 is the standard

jitter analysis software, and Option 101 is the advanced

waveform analysis software. Option 100 includes:

• Decomposition of jitter into Total Jitter (TJ), Random

Jitter (RJ), Deterministic Jitter (DJ), Periodic Jitter

(PJ), Data Dependent Jitter (DDJ), Duty Cycle

Distortion (DCD), and Jitter induced by Intersymbol

Interference (ISI).

• Various graphical and tabular displays of jitter data

• Export of jitter data to convenient delimited text

format

• Save / recall of jitter database
