Features

Three Instruments in One

For basic oscilloscope operation there is easy front
panel access with that familiar analog-look and feel. A
Windows®-based system lets you easily navigate through
the user-interface. The 86100B Infiniium DCA can be
viewed as three high-performance instruments in one. It’s
a general-purpose wide-bandwidth sampling oscilloscope.
It’s a digital communications analyzer. It’s a time domain
reflectometer. Just select the instrument mode and start
making measurements.

Configurable to Meet Your Needs

The 86100B 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.

Digital Communications Analysis

Accurate eye-diagram analysis is essential for character­izing the quality of transmitters used from 100 Mb/s to
40 Gb/s. The 86100B was designed specifically for the
complex task of analyzing digital communications wave­forms. Compliance mask and parametric testing no longer
require a complicated sequence of setups and configura­tions. If you can press a button, you can perform a
complete compliance test. The important measurements
you need are right at your fingertips, including:

• industry standard mask testing with built-in
margin analysis,

• extinction ratio measurements with accuracy and
repeatability, and

• eye measurements: crossing %, eye height and width, ‘1’
and ‘0’ levels, jitter, rise or fall times and more.

The key to accurate measurements of lightwave communi­cations waveforms is the optical receiver. The 86100B
has a broad range of precision receivers integrated
within the instrument.

• Built-in photodiodes, with flat frequency responses,
yield the highest waveform fidelity. This provides high
accuracy for extinction ratio measurements.

• Standards-based transmitter compliance measurements
require filtered responses. The 86100B has a broad
range of filter combinations. Filters can be automati­cally and repeatably switched in or out of the measure­ment channel remotely over GPIB or with a front panel
button. The frequency response of the entire measure­ment path is calibrated, and will maintain its perfor­mance over long-term usage.

• The integrated optical receiver provides a calibrated

optical channel. With the accurate optical receiver built
into the module, optical signals are accurately measured
and displayed in optical power units.

Switches or couplers are not required for an average
power measurement. Signal routing is simplified and
signal strength is maintained.

Eye Diagram Mask Testing

The 86100B provides efficient, high-throughput waveform
compliance testing with a suite of standards based eye­diagram masks. The test process has been streamlined
into a minimum number of keystrokes for testing at
industry standard data rates.

Measurement Speed

Measurement speed has been increased with both fast
hardware and a user-friendly instrument. In the lab, don’t
waste time trying to figure out how to make a measure­ment. With the simple-to-use 86100B, you don’t have to
relearn how to make a measurement each time you use it.

Agilent 86105A Optical Receiver Section

The integrated optical channel can be used as a fully
calibrated SONET/SDH/Gigabit Ethernet or Fibre Channel
reference receiver or as a wide-bandwidth receiver.

Other eye-diagram
masks are easily
created through scaling
those listed at left. In
addition, mask editing
allows for new masks
either by editing
existing masks, or
creating new masks
from scratch. A new
mask can also be
created or modified on
an external PC using a

Built-in Information System

The 86100B has a context­sensitive on-line manual provid­ing immediate answers to your
questions about using the instru­ment. Links on the measure­ment screen take you directly
to the information you need
including algorithms for all of
the measurements. The on-line
manual includes technical specifica­tions of the mainframe and plug-in
modules. It also provides useful
information such as the mainframe
serial number, module serial numbers,
firmware revision and date, and hard
disk free space. There is no need for
a large paper manual consuming
your shelf space.

File Sharing and Storage

Use the internal 10 GB hard drive or

3.5 inch, 1.44 MB floppy disk drive to
store instrument setups, waveforms,
or screen images. Images can be
stored in formats easily imported
into various programs for documen-

tation and further analysis. LAN
interface is also available for network
file management and printing. The
mainframe also has an integrated
CD-ROM drive for firmware upgrades.

Powerful Display Modes

Use gray scale and color graded trace
displays to gain insight into device
behavior. Waveform densities are
mapped to color or easy-to-interpret
gray shades. These are infinite
persistence modes where shading
differentiates the number of times
data in any individual screen pixel
has been acquired.

Internal Triggering
Through Clock Recovery

Very high-speed oscilloscopes are
not capable of triggering directly on
the signal under test. Typically an
external timing reference is used to
synchronize the oscilloscope to the
test signal. In cases where a trigger
signal is not available, clock recovery
modules are available to derive a
timing reference directly from the
waveform to be measured. The
Agilent 8349XA series of clock
recovery modules cover the three
most popular transmission media

used today—electrical lines, multimode, and single-mode
fiber. A built-in coupler reduces external hardware
requirements. All four modules have excellent jitter
performance to ensure accurate measurements. Each
clock recovery module is designed to synchronize to a
variety of common transmission rates.

Clock Recovery Loop Bandwidth

The Agilent clock recovery modules have two loop
bandwidth settings. Loop bandwidth is very important
in determining the accuracy of your waveform when
measuring jitter .

•Narrow loop bandwidth provides a clean system clock
for accurate jitter measurements

• Wide loop bandwidth allows the recovered clock to
track the data and is useful for extracting a signal that
may have propagated through a complex network and
have large amount of jitter. While this obviously negates
any ability to quantify the jitter, it does allow other
parameters of an eye to be measured.

Note: When using recovered clocks for triggering, jitter
measurement accuracy is suspect unless the scheme has
a very narrow loop bandwidth.

Improved Autoscaling

Autoscaling has been significantly improved to provide
quick horizontal and vertical scaling of both pulse and
eye-diagram (RZ and NRZ) waveforms.

Time Domain Reflectometer (TDR)

TDR measurements are focused on high-speed applica­tions where it is necessary to optimize electrical system
components, such as microstrip lines, PC board traces,
SMA edge launchers and coaxial cables where imperfec­tions cause signal distortion and reflections. Signal
integrity is a critical requirement in high-speed digital
signal transmission.

Gated Triggering

Trigger gating port allows easy external control of data
acquisition for circulating loop or burst-data experi­ments. Use TTL-compatible signals to control when the
instrument does and does not acquire data.

Easier Calibrations

Calibrating your instrument has been simplified by
placing all the performance level indicators and calibra­tion procedures in a single high-level location. This
provides greater confidence in the measurements made
and saves time in maintaining equipment.

Stimulus Response Testing
Using the Agilent N4606A SmartBERT

Error performance analysis represents an essential part
of digital transmission test. The Agilent 86100B and
N4906A SmartBERT have similar user interfaces and
together create a powerful test solution.

Transitioning from the Agilent 83480A and
86100A to the 86100B

The 86100B has been designed to be a virtual drop-in
replacement for the Agilent 86100A and Agilent 83480A
digital communications analyzers and Agilent 54750A
wide-bandwidth oscilloscope. All modules used in the
Agilent 83480A and 54750A can also be used in the
86100B. The remote programming command set for the
86100B has been designed for direct compatibility with
software written to control the 86100A, 83480A and
54750A.

When developing 40 Gb/s devices,
even a small amount of inherent
scope jitter can become significant
since 40 Gb/s waveforms only have a
bit period of 25 ps. Scope jitter of
1ps RMS can result in 6 to 9 ps of
peak-to-peak jitter, causing eye
closure even if your signal is jitter­free. The Agilent 86100A and B have
been improved specifically for 40
Gb/s waveform analysis.

the most significant improvements in
wide-bandwidth sampling oscillo­scopes in over a decade.

Jitter
performance has been reduced by
almost an order of magnitude to 200
fs RMS. Oscilloscope jitter is virtu­ally eliminated! The reduced jitter of
the 86107A precision timebase
module allows you to measure the
true jitter of your signal. The 86107A
requires a 10, 20 or 40 GHz electrical
reference clock that is synchronous
with the signal under test. Timebase
resolution has also been improved
from 10 ps/division to 2 fs/division,
a 5 times improvement.

Meeting your growing need
for more bandwidth

Today’s communication signals have
significant frequency content well
beyond an oscilloscope’s 3-dB band­width. A high-bandwidth scope does
not alone guarantee an accurate
representation of your waveform.
Careful design of the scope’s
frequency response (both amplitude
and phase) minimizes distortion
such as overshoot and ringing.

The Agilent 86116A, 86116B and
86109B are plug-in modules that
include an integrated optical
receiver designed to provide the
optimum in bandwidth, sensitivity,
and waveform fidelity. The 86116B
extends the bandwidth of the
86100B Infiniium DCA to 80 GHz
electrical, 65 GHz optical in the
1550nm wavelength band. The
86116A covers the 1300nm and
1550nm wavelength bands with 63
GHz of electrical bandwidth and 53
GHz of optical bandwidth. The
86109B is an economical solution
with 50 GHz electrical and 40 GHz
optical bandwidth. You can build the
premier solution for 40 Gb/s wave­form analysis around the 86100
mainframe that you already own.

(RZ) waveform measurements

measurements are built-in for the
