The Tektronix DSA8200-U Digital Serial Analyzer Sampling Oscilloscope is a versatile tool for communication, computer and consumer electronics gigabit transmitter and signal path characterization, and compliance verification. With exceptional bandwidth, signal fidelity, and the most extensible modular architecture, the DSA8200-U provides the highest performance TDR and interconnect analysis, most accurate analysis of signal impairments, and BER calculations for current and emerging serial data technology.

The DSA8200-U provides unmatched measurement system fidelity with ultra-low jitter floor that ensures the most accurate acquisition of high-speed signals. Users get advanced analysis benefits from the 200 fs acquisition jitter with the Phase Reference module. And in another step forward for a sampling oscilloscope, with the help of the Phase Reference module, the DSA8200-U can acquire and measure SSC (Spread Spectrum Clocking) signals. The multiprocessor architecture, with dedicated per-slot digital signal processors (DSPs), provides fast waveform acquisition rates, reducing the test times necessary for reliable characterization and compliance verification.

The DSA8200-U’s versatile modular architecture supports a large and growing family of plug-ins enabling users to configure their measurement system with a wide variety of electrical, optical, and accessory modules that best suit the application now and in the future. With 6 module slots, the DSA8200-U can simultaneously accommodate a Clock Recovery module, a precision Phase Reference module, and multiple acquisition modules, electrical or optical, so users can match system performance to their evolving needs.

Featuring industry-leading signal fidelity, the family of electrical modules includes bandwidth performance from 12 GHz to 70+ GHz. Two true-differential Time Domain Reflectometer (TDR) modules, with remote samplers, offer up to 50 GHz bandwidth and 15 ps reflected rise time and 12 ps incident rise time. The family of low-noise variable-bandwidth electrical modules provides the industry's best noise performance with remote samplers, featuring 450 μV RMS noise at 60 GHz, and 300 μV RMS at 30 GHz.

The DSA8200-U optical modules provide complete optical test solutions with superior system fidelity from 125 Mb/s to 43 Gb/s and beyond. The modules cover a range of wavelengths for both single- and multi-mode fibres. Each module can be optionally configured with a number of selectable optical reference receiver (ORR) filters and/or a full bandwidth path. The 80C07B, 80C08C, and 80C11 can be configured with a number of available flexible integrated clock recovery options. The 80C12 and 80C14 Multirate module clock recovery support is achieved with an electrical output for use with the 80A05 module, or CR175A/CR125A instruments.

The DSA8200-U’s popular FrameScan acquisition mode can be used with patterns from DUTs, BERTs, and other sources, to isolate pattern-dependent effects in transmitters or show the bit sequence preceding a mask violation. FrameScan automatically sequences the time base so that each bit of the data stream is acquired in time order. When used in combination with mask-testing conditional acquisition features of the DSA8200-U, such as stop after mask hits, FrameScan can automatically identify at which bit a pattern-dependent failure occurred.

In addition, specialized modules supporting features such as single-ended and differential electrical clock recovery, electrostatic protection for the TDR, and connectivity to the popular TekConnect probing system brings users the performance of Tektronix state-of-the-art probes for high-impedance and differential probing. Low-impedance probes for 50 Ω probing and for TDR probing are also available.

Advanced Communication Signal Analysis

Specifically designed for ultra high-performance optical and electrical serial data applications, the DSA8200-U is the ideal tool for design characterization and validation, as well as manufacturing test of datacom and telecom components, transceiver subassemblies, and transmission systems. The DSA8200-U 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, OMA, extinction ratio, Q-factor, mean optical power, and amplitude. In addition, users can do mask testing of SONET/SDH, 100 Gigabit (4×25), 10 Gigabit, Gigabit Ethernet, and other electrical and optical standards compliance verification. Color grading and intensity grading of waveform data adds a third dimension, sample density, to signal acquisitions and analysis to provide visual insight. In addition, the variable persistence database feature enables exact data aging to all of the functions, and facilitates eye measurements on DUTs under adjustment.

OpenChoice Software Enables Familiar Tools to Extend Measurement System

The DSA8200-U provides an open Windows environment offering new levels of data analysis on the instrument using the user's favorite commercially available third-party software packages. Additionally, TekVISA, a standard software accessory, allows the instrument to be placed under the control of software applications (such as LabVIEW, LabWindows, Visual Basic, Microsoft Excel, C, etc.) running on the instrument or on an external PC workstation's network connected to the instrument without the need of a GPIB hardware interface. Plug-and-play drivers for LabVIEW and other programs are also supplied.

The DSA8200-U combines the familiarity of Microsoft's Windows XP operating system with world-class waveform acquisition technology. This platform provides a wide array of standard instrumentation and communications interfaces, including: GPIB, parallel printer port, RS-232-C, USB serial ports, and an Ethernet LAN connection. In addition, the platform includes a DVD-CD/RW combo drive and removable hard drive for storage of waveforms, setups, and analysis results.
