Communication Signal Analyzers

CSA7000 Series

External Timebase Reference

The reference oscillator in CSA7000 Series

analyzers can be phase-locked to an external

10 MHz source to match system stability

or synchronize multiple instruments. This

phase-lock technique also enables charac-

terization of very low frequency wander and

modulation effects.

Waveform Database and
Parametric Measurements

The CSA7000 Series includes waveform

database acquisition mode to provide infor-

mation over a much larger sample of data.

The waveform database is a three-dimensional

accumulation of source waveform data as it

is continuously acquired. In addition to ampli-

tude and timing information, a waveform

database has a third dimension of count.

The count represents the number of times a

specific waveform point (time and amplitude)

has been acquired. Color-graded displays based

on counts can be used to highlight waveform

activity. Parametric measurements derived

from the database use statistical techniques

to produce more stable, accurate results.

Communications
Measurements

The CSA7000 Series provides a broad suite

of eye-pattern related measurements that

are fundamental for analysis of serial com-

munications signals, including extinction

ratio, Q-factor, eye height/width, jitter and

noise. These are complemented with a wide

array of general purpose amplitude, time

and histogram-related measurements.

Application-specific
Software Extensions

Applied measurement extensions can be

installed to enhance CSA7000 capabilities.

These software applications build on the

precision acquisition performance of

CSA7000 Series to address the need for

application-specific measurements to quickly

quantify device and system performance.

Optional applications include:

Advanced jitter analysis, including Rj/Dj

separation and BER analysis

Compliance testing for signaling defined

in ITU-T G.703 and ANSI T1.102
communications standards

Compliance testing for signaling defined in

USB1.0 standard and USB2.0 draft standard

Disk drive read channel, head and media

measurements to IDEMA standards;
PRML measurements

Complete Connectivity

The CSA7000 Series combines a high

performance real-time oscilloscope with a

PC processor in a self-contained unit. With

open access to the Windows operating

environment, built-in applications such as

WordPad, Paint and Internet Explorer allow

users to concurrently maintain lab notes

and reference design information while

working with the instrument, saving time

and reducing errors. The built-in floppy disk

drive provides a convenient means of trans-

porting results while the standard network

interfaces allow easy file sharing and

remote control.

The analysis and connectivity software of the

CSA7000 Series provides a comprehensive

software infrastructure for faster, more ver-

satile operations. Industry-standard protocols,

such as VISA and ActiveX Controls, are

included for using and enhancing Windows

applications such as Excel for data analysis

and documentation. Or, create custom soft-

ware to automate multi-step processes in

waveform collection and analysis with Visual

BASIC, C, C++, MATLAB, HP VEE, and other

common development environments. By

hosting applications on the instrument and

using the embedded PCI bus, waveform data

can be moved directly from the acquisition

system to analysis applications at much faster

speeds than conventional cable connections.

Integration of the instrument with external PCs

and non-Windows hosts is also supported by

CSA7000 Series software solutions. Plug-

and-play drivers are included to enable fast

and easy communication with LabVIEW, Lab

Windows and HP VEE programs using GPIB

and LAN connections. Applications using a

local area network can connect directly to

a CSA7000 Series analyzer using the VXI

11.2 server included in the instrument.
