DSA80000B Digital Signal Analyzer
2-GHz to 13-GHz Oscilloscope Measurement Systems
Data Sheet
Design, debug and validate your serial-data-based designs faster
With today’s higher data rates and serial buses, you need specialized tools to design, debug and validate your designs. Your measurements of low-voltage, differential signals can be impacted by oscilloscope noise, trigger jitter, and probe fidelity. Clock signals are typically embedded in your data, and the data may be 8b/10b encoded, so debugging your signal requires a smart oscilloscope. Once your design is complete, you are faced with compliance testing, which means making many complicated tests in a short amount of time. A standard oscilloscope no longer does the job.
The DSA80000B digital signal analyzer (DSA) is an oscilloscope measurement system optimized for these measurement tasks. The system is built around an Infiniium DSO80000B Series oscilloscope and the InfiniiMax probing system. The oscilloscope and probe capabilities are augmented with high-speed serial data analysis and EZJIT Plus jitter analysis software to give you the capabilities you need for designing, debugging and validating serial-data-based designs.
Key features:
• 2 to 13 GHz bandwidth real-time with up to 40 GSa/s sample rate
• Industry’s lowest noise floor, jitter measurement floor, trigger jitter, and flattest frequency response
• Industry’s only full bandwidth probe system for all use models – up to 13 GHz bandwidth for differential solder-in, browser and SMA connections
• Serial data analysis with clock recovery, 8b/10b decode, and symbol search/trigger
• Jitter analysis with random jitter (RJ) and deterministic jitter (DJ) decomposition
• Upgrade program allows you to upgrade to a higher bandwidth model, protecting your investment
• LXI functional class C compliant

The high-speed serial data analysis software provides you with a fast and easy way to pinpoint signal integrity problems and validate performance for serial interface designs. It allows you to perform mask testing, characterize serial data streams that employ embedded clocks, and decode 8b/10b data from serial data streams. The software enables you to verify compliance to computer, communication, and data communications standards such as PCI Express®, Serial ATA (SATA), Serial attached SCSI (SAS), Fibre Channel (FC), XAUI and Gigabit Ethernet.
Figure 1. The serial data setup wizard quickly sets up a measurement by defining the signal, the clock recovery method, and what you want displayed.
Key features:
• Measurement setup wizard for ease-of-use
• Clock recovery first-order or second-order PLL, external reference clock
• Real-time eye diagram display
• Masks for PCI Express, SATA, SAS, Fibre Channel, Gigabit Ethernet and XAUI
• Eye mask unfolding
• 8b/10b decoding of serial data
• Symbol search and trigger
A serial data wizard walks you quickly through the steps required to setup and perform a measurement. Intuitive displays and clear labeling of information make it easy to comprehend measurement results.
Serial data analysis with clock recovery
3
Flexible clock recovery
Embedded clocks can be recovered via constant-frequency, first-order phase-locked loop (PLL), or second-order PLL approaches. You can adjust the center frequency and bandwidth, and in the case of second-order PLL, the damping factor. For PCI Express, the clock recovery algorithm specified by the PCI-SIG® is provided. When you choose PLL clock recovery, the clock recovery algorithm requires some time at the start of each record to lock to the data. This interval cannot be viewed or analyzed. The serial data wizard will indicate the required time period for the clock recovery algorithm to lock.
Figure 2. An eye mask test on a failing Serial ATA signal. The information below the mask screen helps you determine the level of confidence in meeting your desired bit error rate.
Figure 3. The 8b/10b decoded symbol information is displayed below the appropriate portion of a PCI Express signal.
Real-time eye analysis
The real-time eye display is reconstructed from all unit intervals in the oscilloscope memory aligned by the recovered clock. In this display mode the center screen (or zero in the time base) corresponds to the active edge of the recovered clock. Once you identify a failure of the eye mask, you can unfold the eye diagram to show the specific unit interval that caused the failure. When you use it with the 8b/10b decoding feature, you can identify data-dependent errors that result in eye mask violations caused by inter-symbol interference (ISI). Or use 8b/10b decode to assist you with debugging during the link bring-up phase of development.

With the faster edge speeds and shrinking data valid windows in today’s high-speed digital designs, insight into the causes of signal jitter is critical for ensuring the reliability of your design. The EZJIT Plus jitter analysis software helps to identify and quantify jitter components. Time correlation of jitter to the real-time signal makes it easy o trace jitter components to their sources.
Figure 4. The EZJIT Plus setup wizard prompts you to select measurement thresholds, parameters to display, and for RJ/DJ analysis, the data pattern type, TJ BER calculation level, and clock recovery method.
Key features:
• Easy-to-use jitter measurements
• Measure repetitive or arbitrary data waveforms
• Constant frequency or PLL clock recovery
• Real-time measurement trend, histogram, and spectrum displays
• Separation of RJ, DJ, PJ, DDJ, ISI jitter subcomponents
• TJ estimation at low BER
• Graphical displays of DDJ versus bit, histograms and bathtub curve
The EZJIT Plus setup wizard helps you quickly set up the oscilloscope and begin taking measurements. With time-correlated jitter trend and signal waveform displays, you can clearly see the relationships between jitter and signal conditions. Intuitive displays and clear information labeling make it easy to comprehend measurement results.
Jitter analysis with RJ/DJ decomposition
5
Easily review jitter parameters
The 4-in-1 jitter display allows for multiple views of jitter populations and distributions, data-dependent jitter versus bit in repetitive patterns, as well as the bathtub curve plot, which measures eye-opening versus bit error rate. Composite histogram displays relative contributions of data-dependent jitter, total jitter, random jitter and periodic jitter. Total jitter is a convolution of the data-dependent jitter probability density function (PDF) and the random/periodic jitter PDF.
Figure 6. The EZJIT Plus 4-in-1 results display provides a comprehensive view of the jitter components. You control which parameter is displayed and where. Plus, you can quickly toggle between the jitter analysis screen and the measured signal.
Figure 5. For debugging jitter problems, the histogram display plots the relative occurrence of values for the measured parameter, the trend display shows a time plot of the measurement time-correlated with the signal waveform data, and the spectrum display shows the spectral content of the jitter.
RJ/DJ results with confidence
With RJ/DJ separation required by many standards today, you need confidence that you’re making accurate, repeatable jitter measurements. The RJ/DJ jitter separation in EZJIT Plus software uses similar algorithms to those used in Agilent’s 86100C DCA-J, giving you confidence that your measurement results are accurate and repeatable across multiple platforms. EZJIT Plus software also allows you to choose between periodic and arbitrary data modes when you analyze jitter for compliance.

Low-voltage, differential measurements require a low-noise receiver and probe. The DSA80000B DSA and the InfiniiMax probing system feature the industry’s lowest noise floor, lowest jitter measurement floor, lowest trigger jitter and flattest frequency response. These foundational capabilities are crucial for achieving accurate and repeatable measurements. These superior signal integrity capabilities come from Agilent’s RF design experience, proprietary packaging technologies and unique CMOS ADC architecture. Superior signal integrity maximizes your design margins by not wasting any measurement accuracy due to the poor noise, jitter or frequency response of the oscilloscope or probing system.
Figure 7. With the industry’s lowest noise floor, the DSA80000B delivers superior measurement results and maximizes design margins.
Figure 8. With the industry’s lowest trigger jitter – less than 500 fs rms (typically, less than 200 fs rms on 5 Gb/s PRBS signal) – the DSA80000B facilitates accurate waveform viewing of multiple waveforms.
Key features:
• Industry’s lowest noise floor for both oscilloscopes and probes – < 419 µV rms @ 5 mV/div (13 GHz bandwidth)
• Industry’s lowest jitter measurement floor – < 0.7 ps rms (13 GHz bandwidth)
• Industry’s lowest trigger jitter – < 500 fs rms (13 GHz bandwidth)
• Industry’s flattest frequency response
• Industry’s only full-bandwidth probe system for all use models – up to 13 GHz bandwidth for differential solder-in, browser and SMA connections

Once your design is done, you need to validate its performance relative to the industry-standard specifications. Performing compliance tests can be a long, complicated process. In fact, some measurements are difficult to make manually. The DSA80000B supports several compliance test software packages based upon a common Infiniium test framework. The Infiniium test framework saves you time by setting the stage for automatic execution of compliance electrical tests. Part of the difficulty in performing compliance electrical tests is properly connecting to the oscilloscope, loading the proper setup files, and then analyzing the measured results by comparing them to limits published in the specification. The Infiniium test framework does much of this work for you.
Key features:
• Task-driven flow for defining measurements, connections, and measurement setup
• Results displayed with pass/fail, margin, and supporting waveforms
• Electrical compliance solutions for computation standards: PCI Express, USB, Ethernet, Firewire
• Electrical compliance solutions for memory standards: FBD, DDR
• Electrical compliance solutions for storage standards: FC, SATA, SAS
• Electrical compliance solutions for video standards: DVI, HDMI
You can easily choose what measurements to make, then the Infiniium test framework automatically configures the oscilloscope for each test, instructs you how to configure the test setup, and makes all measurements, minimizing setup changes. The results are provided in an informative results report that includes margin analysis indicating how close your product is to passing or failing that specification. Compliance test packages are available for many industry standards – see Table 1 for solutions available from Agilent and our partners.
Figure 10. Infiniium test framework guides you quickly through selecting and configuring tests, setting up the connection, running the tests, and viewing the results. You can easily select individual tests or groups of tests with a mouse-click.
