Communication Signal Analyzers

CSA7000 Series

Clock Recovery

CSA7000 Series analyzers include clock
recovery for electrical and optical serial data
streams from 1.5 MBaud to 2.5 GBaud.
Users can easily and reliably perform mask
testing and parametric analysis with a single
connection. Recovered clock and data signals
are available on the front panel for connection
to other equipment, such as a BER analyzer.

Serial Pattern Trigger

The CSA7000 Series includes hardware­based serial pattern trigger to isolate data
patterns. Serial trigger provides a direct
means to analyze pattern dependent issues,
even on a single-shot basis.The combination
of serial trigger and signal averaging reduces
random noise, enhancing acquisition of low
power signals. Users can specify patterns
with up to 32 bits, including “don’t-care”
bits.The serial trigger system can be clocked
from an external source or internal clock
recovery can be applied, providing single­connection convenience.

Unprecedented
Simplicity

Integrated Optical
Reference Receiver

Compliance testing for optical standards
requires calibrated optical reference receiver
response. CSA7000 Series models include
a broad wavelength optical input enabling
them to conveniently address a wide range
of standards.A complete library of optical
reference receiver filters ensures versatility
and eliminates the need for reconfiguring
external modules or plug-ins. Filters can
easily be disabled to provide full-bandwidth
analysis on optical signals.The CSA7404
includes reference receiver filters implementing
fourth-order Bessel-Thompson response for
the following standards and bit rates:

SONET/SDH
OC-48/STM16 FEC, OC-48/STM16,

OC-12/STM4, OC-3/STM1, OC-1/STM0
VSR (1.24416 Gbps)
Fibre Channel 2125, 1063, 531, 266, 133
Gigabit Ethernet
InfiniBand 2.5 Gbps
IEEE 1394b S1600, S800, S400

The integrated O/E architecture of the
CSA7000 Series provides a robust, fully
calibrated signal path and eliminates the
need to match an external O/E adapter to a
specific instrument.The real-time architecture
of the CSA7000 Series is quickly user­configurable with an optical channel and
three electrical inputs or with four electrical
inputs.The output of the O/E is available
on the front panel for use with other
instrumentation.

Mask Testing

The CSA7000 Series provides a complete
portfolio of masks for verifying compliance
to optical and electrical standards. Engineers
can verify circuit design performance and
perform interface compliance testing with
one real-time instrument, even when devel­oping multi-standard and multi-rate designs.

Standard masks include:

SONET/SDH GR 253-Core (51.4 Mbps

to 2.666 Gbps)
Ethernet IEEE Std 802.3,ANSI X3.263

(125 Mbps to 1.25 Gbps)
Fibre Channel ANSI X3.230 (132.8 Mbps

to 2.125 Gbps)
Fibre Channel Electrical (132.8 Mbps

to 2.125 Gbps)
InfiniBand (2.5 Gbps)
ITU-T G.703 (1.544 Mbps to 155.52 Mbps)
ANSI T1.102 (1.544 Mbps to 155.52 Mbps)

USB (12 Mbps, 480 Mbps)
Serial ATA (1.5 Gbps)
IEEE 1394b (393 Mbps to 1.5729 Gbps)
PCI Express (2.5 Gbps)
Rapid I/O (500 Mbps to 2 Gbps)
SPI-5 (2.488 Gbps)
SFI-5 (2.488 Gbps)
TFI-5 (2.488 Gbps)
VSR (1.24416 Gbps)

Several powerful features allow users to easily
tailor mask testing for specific requirements:

One-button Autoset matches instrument

settings to signal characteristics and
specific mask requirements

Optional Auto-Fit process optimizes signal

position within the mask to minimize hits

Mask Margin control adjusts tolerance

during testing

Hit-counting identifies location and degree

of failures

Optional test-related actions including

notification, logging and hardcopy

Built-in mask editing allowing users to

copy and adjust mask values from
a standard, or create new masks

Mask testing results are reported live, providing
real-time feedback. Mask hits are highlighted
on the display and accompanied by readouts
indicating waveforms tested, pass/fail results
and hit counts.A log file summarizing test
results can also be generated automatically.
Users can take advantage of the open Windows
platform to quickly copy and paste test result
screen images or log file information into
reports created with WordPad or other
applications on the instrument.

the CSA7000 Series combines optical
reference receiver filters, clock recovery,
serial pattern trigger and mask testing
into a real-time oscilloscope.

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 charac­terization of very low frequency wander and
modulation effects.

Waveform Database and
Parametric Measurements

The CSA7000 Series includes waveform
database acquisition mode to provide infor­mation 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 ampli­tude 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.

Communication Signal Analyzers

Figure 2.Waveform database acquisition,
statistical techniques and eye pattern-specific
measurements produce stable, accurate
characterization of communications designs.
Color grading in this example highlights the
most frequent occurrences in red.

Communications
Measurements

The CSA7000 Series provides a broad suite
of eye-pattern related measurements that
are fundamental for analysis of serial com­munications 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

voice control software

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 trans­porting 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 ver­satile 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 soft­ware 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. Plug­and-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.
