The DSA8300 Digital Serial Analyzer is the most versatile tool for developing and testing communications, computers, and consumer electronics which utilize multi-gigabit data transmission. It is used for optical and electrical transmitter characterization as well as compliance verification for devices, modules, and systems used in these products.

In addition, the DSA8300 is well-suited for electrical signal path characterization, whether for packages, PCBs, or electrical cables. With exceptional bandwidth, signal fidelity, and the most extensible modular architecture, the DSA8300 provides the highest-performance TDR and interconnect analysis, most accurate analysis of signal impairments, and BER calculations for current and emerging serial data technology.

Finally, with its exceptional signal fidelity and resolution, the DSA8300 is the gold standard for electrical and optical applications which require ultra-high bandwidths, very fine vertical resolution, low jitter, and/or exceptional time interval accuracy.

The DSA8300 provides unmatched measurement system fidelity with the lowest native instrument jitter floor (425 fs RMS, typical for serial data signals at rates >1.25 Gb/s) that ensures the most accurate acquisition of up to 8 high-bandwidth signals simultaneously. You get additional analysis benefits from acquisition jitter as low as 100 fs RMS when using the Phase Reference module (82A04B).

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 DSA8300’s versatile modular architecture supports a large and growing family of plug-ins enabling you to configure your measurement system with a wide variety of electrical, optical, and accessory modules that best suit your application now and in the future. With 6 module slots, the DSA8300 can simultaneously accommodate a Clock Recovery module, a precision Phase Reference module, and multiple acquisition modules, electrical or optical, so you can match system performance to your evolving needs. The ability to swap sampling modules without powering down the DSA8300 (available for scopes with firmware versions 6.1 and later) provides additional flexibility in configuring your DSA8300 to changing test needs.

*¹ The DSA8300 does not support the 80A06 Pattern Synchronization module as this capability is superseded by the integrated Advance Trigger option (Option ADVTRIG) for the DSA8300.

Jitter, Noise, BER, and Serial Data Link Analysis

High-speed serial data link measurements and analysis are supported with three software solutions: 80SJARB, 80SJNB Essentials, and 80SJNB Advanced.*²

• 80SJARB (Option JARB) is a basic jitter measurement tool capable of measuring jitter on any waveform – random or repetitive. The simplicity of acquisition limits the amount of analysis possible so only the simplest decomposition can be used; repeatability is pattern dependent
• 80SJNB Essentials (Option JNB) offers complete analysis of jitter, noise, and BER, with decomposition of components for clear understanding of a signal’s problems and margins. The acquisition methodology requires a repetitive pattern. Both accuracy and repeatability are improved relative to 80SJARB since the tool has access to the complete signal pattern
• 80SJNB Advanced (Option JNB01) adds features to 80SJNB Essentials for serial data link analysis – de-embedding of fixture, channel emulation, FFE/DFE equalization, and pre-emphasis/de-emphasis

Jitter Analysis of Arbitrary Data (80SJARB)

The 80SJARB jitter measurement application software for the DSA8300 Series addresses IEEE 802.3ba applications requiring the J2 and J9 jitter measurements. It also enables basic jitter measurements for NRZ data signals including PRBS31, random traffic, and scrambled data. This provides an entry-level jitter analysis capability with simple Dual Dirac model jitter analysis and no pattern synchronization requirement. 80SJARB can acquire continuously in Free Run mode, delivering acquisitions and updates beyond the IEEE minimum requirement of 10,000 data points. Plots include jitter bathtub curves for both measured and extrapolated data, as well as a histogram of the acquired data.

TDR (Time Domain Reflectometry) Applications

The DSA8300 is the industry’s highest-performance fully integrated Time Domain Reflectometry (TDR) measurement system. Offering true-differential TDR measurements up to 50 GHz bandwidth with 15 ps reflected rise time and 12 ps incident rise time*³, the DSA8300 enables you to keep pace with today’s most demanding Serial Data Network Analysis (SDNA) requirements.

The 80E10B and 80E08B TDR modules feature a fully integrated independent dual-channel 2-meter remote sampler system to minimize fixturing and assure optimal system fidelity. Independent sampler deskew ensures fast and easy fixture and probe de-embedding. The user can characterize differential crosstalk by using TDR steps from a differential module to drive one line pair while monitoring a second line pair with a second differential module.

The DSA8300 is the industry’s most versatile TDR measurement system, accommodating up to 4 dual-channel true-differential TDR modules for fast, accurate multilane impedance and S-parameter characterization.

The P80318 True-differential TDR probe and P8018 Single-ended Passive Handheld TDR probe provide high-performance probing solutions for circuit board impedance and electrical signal characterization. The P80318, an 18 GHz 100 Ω input-impedance differential TDR hand probe, enables high-fidelity impedance measurements of differential transmission lines. The adjustable probe pitch enables a wide variety of differential line spacing and impedances. The P8018 is a 20 GHz Single-ended Passive Handheld TDR probe. Both the P80318 and P8018 can be used as stand-alone probes but are especially designed to work with the 80A02 for the control of EOS/ESD protection.

*³ Rise times are 10-90%. Typical reflected rise times for the 80E10B are <10 ps.

Multi-gigabit Signal Path Characterization and Analysis – Serial Data Network Analysis (SDNA)

As clock speeds and rise times of digital circuits increase, interconnect signal integrity dramatically affects digital system performance. Accurate and efficient Serial Data Network Analysis (SDNA) of the signal path and interconnects in time and frequency domains is critical to predict signal losses, jitter, crosstalk, terminations and ringing, digital bit errors, and eye diagram degradation, ensuring reliable system operation.

Tektronix offers several true-differential TDR modules, which in combination with IConnect^® software allow S-parameter measurements with up to –70 dB of dynamic range. This performance assures accurate, repeatable measurements in serial data analysis, digital design, signal integrity, and electrical compliance testing applications.

TDR Module Performance with IConnect^®

TDR Module	S-parameter Measurement Bandwidth Performance
80E10B	50 GHz
80E08B	30 GHz
80E04	20 GHz

With the long record length acquisitions, IConnect^® provides great flexibility for obtaining the desired frequency range and frequency step when performing S-parameter measurements. Up to 1,000,000 points can be acquired.

When you employ IConnect^® Signal Integrity TDR and S-parameter software with the DSA8300 you have an efficient, easy-to-use, and cost-effective solution for measurement-based performance evaluation of multi-gigabit interconnect links and devices, including signal integrity analysis, impedance, S-parameter, and eye-diagram tests, and fault isolation. IConnect^® can help you complete interconnect analysis tasks in minutes instead of days, resulting in faster system design time and lower design costs. IConnect^® also enables impedance, S-parameters, and eye-diagram compliance testing as required by many serial data standards, as well as full channel analysis, Touchstone (SnP) file output, and SPICE modeling for multi-gigabit interconnects.

Failure Analysis – Quickly Identify Fault Location

Quickly identify the exact location of faults with the 80E10B sub-millimeter resolution and IConnect^® True Impedance Profile.

The 80E10B, with its 12 ps typical TDR rise time, provides superior resolution enabling the fastest and most efficient fault isolation in package, circuit board, and on-chip failure analysis applications.

IConnect^® Signal Integrity TDR and S-parameter Software

Operating on the DSA8300 TDR platform, IConnect^® S-parameters is the most cost-effective and highest throughput approach for S-parameter measurements in digital design, signal integrity analysis, and interconnect compliance testing, providing as much as 50% cost savings compared to similar bandwidth VNAs, and dramatically speeding up measurements.

You can also take advantage of the IConnect^® S-parameters command-line interface, which automates the S-parameter measurements to the overall suite of manufacturing tests you perform using your TDR instrument, significantly reducing test time while increasing measurement repeatability.

The simplicity of S-parameter calibration using a reference (open, short, or through), and an optional 50 Ω load makes measurements, fixture de-embedding, and moving the reference plane a snap. Touchstone file format output enables easy S-parameter file sharing for further data analysis and simulations.

Tektronix offers several true-differential TDR modules, which in combination with IConnect^® offers S-parameter measurements up to 50 GHz with up to –70 dB of dynamic range. This performance exceeds requirements for serial data analysis, digital design, and signal integrity applications, resolving down to 1% (–40 dB) accuracy of crosstalk, while electrical compliance testing masks typically call for measurements in the –10 to –30 dB range.

• IConnect^® software allows you to quickly and easily generate SPICE and IBIS models for your PCBs, flex boards, connectors, cables, packages, sockets, and I/O buffer inputs directly from TDR/T or VNA S-parameter measurements
• IConnect^® allows you to display eye diagram degradation, jitter, loss, crosstalk, reflections, and ringing in your digital system
• IConnect^® Linear Simulator allows the designer to link several interconnect channels together to evaluate the total time, frequency domain performance, and eye diagram of the overall channel
• IConnect^® substantially simplifies the signal integrity analysis of the interconnect link, equalization and emphasis component design, and analysis of the interconnect link with transmitter and receiver

Clock Recovery for Optical Testing

In many optical applications, there is no data clock directly available to provide a reference signal for acquiring the signals from the device under test. In these situations, it is necessary to recover the clock from the data signal. The Tektronix 8000 Series of sampling oscilloscope products provides a complete complement of clock recovery solutions to meet this need. Each of these solutions is fully calibrated so that users do not need to do any manual calibration of the system to take into account any losses due to data pick-off being routed to the input of the clock recovery unit. Shown below is a clock recovery solutions selection guide with the key specifications for each solution to assist you in selecting the solution(s) most appropriate for your application. For more detailed information on these solutions, see the 80Cxx Optical Sampling Modules datasheet (for clock recovery options integrated into the 80C07B, 80C08D, or 80C11B ) or the appropriate clock recovery datasheets for stand-alone clock recovery modules or instruments.

Measurement and Analysis Tools for Optical Testing Applications

The DSA8300 includes a wide variety of measurement and analysis tools which specifically address optical testing applications. In addition to the standard amplitude and timing parametric measurements (e.g. rise/fall times, amplitude, RMS jitter, RMS noise, frequency, period, etc.) the measurement suite for the DSA8300 includes measurements specifically tailored to measuring optical signals (average optical power, extinction ratio, eye height, eye width, optical modulation amplitude (OMA), etc.). For a complete list of measurements, see the Math/Measurement section of this datasheet.

The DSA8300 also includes standard compliance testing masks for all of the common optical standards from 155 Mb/s to 100 Gb/s. The DSA8300 mask testing system includes the ability to automatically fit standard and user masks to data acquired into a waveform database. Users can also create their own masks for automated mask testing. Histograms and cursor measurements are also available to analyze optical signals acquired by the DSA8300.

Finally, the 80SJNB applications support complete jitter, noise, and BER analysis for optical signals. The advanced version of this software (Option JNB01) supports evaluating the emphasis and equalization on impaired signals.

S-parameter Performance Characteristics (80E10B)

Measurement Conditions

• All measurements were performed after proper warm up as specified in the DSA8300 manual
• Standard S-parameter dynamic range measurement practices were used to determine the dynamic range of the module
• Uncertainty results were derived from a wide range of devices, with 250 averages
• Better dynamic range can be achieved by selecting lower bandwidth settings on the 80E10B module due to a lower RMS noise floor
• Results apply to single-ended or differential measurements
