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 hardware-
based 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 single-
connection 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 user-
configurable 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 devel-
oping 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.
