Specifically designed for high-performance communications applications, the CSA8000 Communications Signal Analyzer is the ideal tool for design evaluation and manufacturing test of datacom and telecom components, transceiver subassemblies and transmission systems.

The CSA8000 generates measurement results, not just raw data, with time and amplitude histograms, mask testing and statistical measurements. It provides a communications-tailored measurement set that includes jitter, noise, duty cycle, overshoot, undershoot, extinction ratio, Q-factor, mean optical power and amplitude measurements.

In addition, mask testing of SDH/SONET, Gigabit Ethernet and other standards simplifies compliance testing.

A large, full color display helps you to discriminate waveform details. Color-grading of waveform data adds a third dimension - sample density - to your signal acquisitions and analysis.

The CSA8000 supports a large and growing family of electrical, 40 Gigabit optical and optical plug-in modules. This modular architecture lets you configure the instrument with the right features for your application both now and in the future.

The available optical modules provide complete optical test solutions for both telecom (622 Mb/s to 40 Gb/s) and datacom (Fibre Channel and Gigabit Ethernet) applications.

The 40 Gigabit optical sampling modules provide performance testing for leading-edge applications in the design and manufacture of optical communication network elements and optical components.

Each optical module includes all of the elements necessary for communications testing; including an optical to electrical converter, an average power monitor, one or more reference receiver filters, a full bandwidth path and a low-noise electrical sampler. In addition, clock recovery is available as an option for all optical modules.

The electrical plug-ins include a variety of modules with bandwidths up to 50 GHz and specialized features such as TDR. High bandwidth probes are also available for constructing a total acquisition and measurement solution.

With its industry-best horizontal stability, trigger jitter, signal sensitivity and noise performance, the CSA8000 ensures the most accurate acquired signal for high-speed optical communications testing.

The CSA8000's multi-processor architecture, with dedicated per channel Digital Signal Processors (DSP), also provides industry-best waveform acquisition rates that shorten test times.

The CSA8000's FrameScan^TM acquisition mode can be used with a variety of BERTs and/or protocol analyzers to isolate pattern dependent effects in transmitters or show the bit sequence leading up to a mask violation. FrameScan acquisition mode also allows the averaging of eye diagrams. This can be used to extract a clean eye diagram from noisy low-level signals.

The CSA8000 is built on Tektronix' new sampling oscilloscope platform that combines familiar MS Windows-based PC technologies with world-class waveform acquisition technology.

This platform provides a wide array of standard instrumentation and communications interfaces (such as GPIB, Parallel Printer Port, RS-232-C and USB Serial Ports and an Ethernet LAN connection). In addition, the platform includes several mass storage devices (floppy disk, removable hard drive and CD-ROM).

Finally, since the system supports an open Windows environment, new levels of data analysis can be done directly on the instrument using commercially available software packages.
