Physical-layer structures have increasingly become the bottleneck in high-speed

digital system performance. As bus speeds, clock speeds, and link speeds all

push past the gigabit-per-second mark, digital data no longer looks like simple

ones and zeros. In fact, digital data begins to exhibit analog behavior such as

reflections from discontinuities, dispersive loss, crosstalk, and EMI radiation

and susceptibility. Analog analysis can be the key to solving such digital

problems as overshoot, undershoot, ringing, rise-time degradation, pulse

droop, dropout, ground bound and eye closure.

As the combination of digital and analog analysis in several modes of operation

becomes more important, the need for multiple test solutions becomes diffi-

cult to manage. A single test solution that can fully characterize high-speed

differential devices while leaving domain and format of the analysis up to

the designer becomes the tool of choice. The four-port network analyzer-based

Physical Layer Test System (PLTS) does just that.

Designing gigabit-per-second devices will require the combination of time-

domain and frequency-domain analysis. The Agilent N1900A series Physical

Layer Test System is the premier signal integrity solution for designing and

validating high-speed differential interconnects. PLTS combines frequency-

domain, time-domain, and eye diagram analysis to provide a comprehensive

view of device performance. With a single setup to your device, you can

measure all transmission and reflection terms for all possible modes of

operation, including single-ended, differential, common, and mixed modes.

Features

• Powerful signal integrity analysis

tools include time-domain reflectometry

(TDR), time-domain transmission

(TDT), frequency-domain, and eye

diagram analysis

• Completely characterize the single-

ended, differential-mode, common-

mode, and mode conversion behavior

of your device

• RLCG parameter extraction allows

creation of accurate transmission line

models for use in simulation programs

such as HSPICE

• High dynamic range provides a view

into elusive EMI problems that

previously may have

gone undetected

Agilent PLTS systems combine a

vector network analyzer, an external test

set, and software with advanced analysis

tools to provide the highest accuracy pos-

sible for measuring inactive single-ended

or differential physical-layer components

such as back-planes, high speed serial

cables, interconnects, and packages.
