Eyeline ModeEyeline Mode is a new feature only available in the86100C that provides insight into the effects of specificbit transitions within a data pattern. The unique viewassists diagnosis of device or system failures do tospecific transitions or sets of transitions within apattern. When combined with mask limit tests, EyelineMode can quickly isolate the specific bit that caused amask violation.Eyeline Mode uses PatternLock triggering to build up aneye diagram from samples taken sequentially throughthe data pattern. This maintains a specific timingrelationship between samples and allows Eyeline Modeto draw the eye based on specific bit trajectories.Effects of specific bit transitions can be investigated,and averaging can be used with the eye diagram.Traditional triggering methods on an equivalent timesampling scope are quite effective at generating eyediagrams. However, these eye diagrams are made up ofsamples whose timing relationship to the data pattern iseffectively random, so a given eye will be made up ofsamples from many different bits in the pattern takenwith no specific timing order. The result is thatamplitude versus time trajectories of specific bits inthe pattern are not visible. Also, averaging of the eyediagram is not valid, as the randomly related sampleswill effectively average to zero.Measurement speedIn manufacturing, it is a battle to continually reduce thecost per test. Solution: Fast PC-based processors, resultingin high measurement throughput and reduced test time.Oscilloscope modeMeasureStandard measurements/featuresThe following measurements are available from the toolbar, as well as the pull down menus. Measurementsavailable are dependent on the DCA-J operating mode.Jitter ModeJitter Mode requires Option 001 Enhanced Trigger hardware.There are two jitter analysis software packages for theDCA-J. Option 100 is the standard jitter analysissoftware, and Option 101 is the advanced waveformanalysis software.

Built-in information systemClock recovery loop bandwidthThe 86100C has a contextsensitive on-line manualproviding immediate answersto your questions about usingthe instrument. Links on themeasurement screen take youdirectly to the information youneed including algorithms forall of the measurements. The on-linemanual includes technicalspecifications of the mainframe andplug-in modules. It also providesuseful information such as themainframe serial number, moduleserial numbers, firmware revisionand date, and hard disk free space.There is no need for a large papermanual consuming your shelf space.The Agilent clock recovery moduleshave two loop bandwidth settings.Loop bandwidth is very importantin determining the accuracy of yourwaveform when measuring jitter, aswell as testing for compliance. Narrow loop bandwidth providesa clean system clock for accuratejitter measurements Wide loop bandwidth in someapplications is specified in thestandards for compliance testing.It allows the recovered clock totrack the data and is useful forextracting a signal that may havepropagated through a complexnetwork and have large amounts ofjitter. While this obviously negatesany ability to quantify the jitter, itdoes allow other parameters of aneye to be measured.File sharing and storageUse the internal 40 GB hard drive tostore instrument setups, waveforms,or screen images. A 64MB USBmemory stick is included with themainframe. Combined with the USBport on the front panel this providesfor quick and easy file transfer.Images can be stored in formatseasily imported into variousprograms for documentation andfurther analysis. LAN interface isalso available for network filemanagement and printing. Anexternal USB CD-RW drive isincluded with the mainframe. Thisenables easy installation of softwareapplications as well as storage oflarge amounts of data.Powerful display modesUse gray scale and color graded tracedisplays to gain insight into devicebehavior. Waveform densities aremapped to color or easy-to-interpretgray shades. These are infinitepersistence modes where shadingdifferentiates the number of timesdata in any individual screen pixelhas been acquired.Internal triggeringthrough clock recoveryTypically an external timingreference is used to synchronize theoscilloscope to the test signal. Incases where a trigger signal is notavailable, clock recovery modules areavailable to derive a timing referencedirectly from the waveform to bemeasured. The Agilent 8349XA seriesof clock recovery modules areavailable for electrical, multimodeoptical, and single-mode opticalinput signals. All 8349XA moduleshave excellent jitter performance toensure accurate measurements. Eachclock recovery module is designed tosynchronize to a variety of commontransmission rates.Note: When using recovered clocksfor triggering, the amount of jitterobserved will depend on the loopbandwidth. As the loop bandwidthincreases, more jitter is “trackedout” by the clock recovery resultingin less observed jitter. This isdesired by many standards, butit is important in a measurementenvironment to understand theeffect that the clock recovery has onthe quantity of jitter being measured.7

Waveform autoscalingAutoscaling provides quick horizontal and vertical scalingof both pulse and eye-diagram (RZ and NRZ) waveforms.Time domain reflectometery/time domaintransmission (TDR/TDT)High-speed design starts with the physical structure.The transmission and reflection properties of electricalchannels and components must be characterized toensure sufficient signal integrity. Reflections and signaldistortions must be kept at a minimum. Use TDR andTDT to optimize microstrip lines, PC board traces, SMAedge launchers and coaxial cables.Calibration techniques, unique to the 86100C, providehighest precision by removing cabling and fixturingeffects from the measurement results. Translation ofTDR data to complete single-ended, differential, andmixed mode S-parameters are available through theN1930A Physical Layer Test System software. Highertwo-event resolution and ultra high-speed impedancemeasurements are facilitated through TDR pulseenhancers from Picosecond Pulse Labs1.Gated triggeringTrigger gating port allows easy external control of dataacquisition for circulating loop or burst-dataexperiments. Use TTL-compatible signals to controlwhen the instrument does and does not acquire data.Easier calibrationsCalibrating your instrument has been simplified byplacing all the performance level indicators andcalibration procedures in a single high-level location.This provides greater confidence in the measurementsmade and saves time in maintaining equipment.1 Picosecond Pulse Labs (www.picosecond.com)8Stimulus response testingUsing the Agilent N490XA Serial BERTError performance analysis represents an essential partof digital transmission test. The Agilent 86100C andN490XA Serial BERT have similar user interfaces andtogether create a powerful test solution.Transitioning from the Agilent 83480A and86100A/B to the 86100CWhile the 86100C has powerful new functionality thatits predecessors don’t have, it has been designed tomaintain compatibility with the Agilent 86100A, 86100Band Agilent 83480A digital communications analyzersand Agilent 54750A wide-bandwidth oscilloscope. Allmodules used in the Agilent 86100A/B, 83480A and54750A can also be used in the 86100C. The remoteprogramming command set for the 86100C has beendesigned so that code written for the 86100A or 86100Bwill work directly. Some code modifications are requiredwhen transitioning from the 83480A and 54750A, butthe command set is designed to minimize the level ofeffort required.

Lowest intrinsic jitterThe patented 86107A precisiontimebase reference module representsone of the most significantimprovements in wide-bandwidthsampling oscilloscopes in over adecade. Jitter performance hasbeen reduced by almost an orderof magnitude to 200 fs RMS.Oscilloscope jitter is virtuallyeliminated! The reduced jitter of the86107A precision timebase moduleallows you to measure the true jitterof your signal. When using the86107A, the minimum timebaseresolution for oscilloscope andeye/mask displays is 500 fs/division,rather than 2 ps/div with thestandard timebase.The standard timebase of the86100C has very low intrinsicjitter compared to other advancedwaveform analysis solutions.However, for users who need theabsolute best sensitivity for theirjitter measurements, the 86107Aprovides the ultimate timebaseperformance. Using the 86107Awith Jitter Mode requires theOption 101 Advanced WaveformAnalysis software package. Jittermeasurements with the 86107A aretargeted at users who are trying toaccurately measure very low levelsof jitter and need to minimize thejitter contribution of the scope.The 86107A requires an electricalreference clock that is synchronouswith the signal under test. Forspecific requirements of the clocksignal, see the 86107A specificationson page 11.Accurate views of your40 Gb/s waveformsWhen developing 40 Gb/s devices,even a small amount of inherentscope jitter can become significantsince 40 Gb/s waveforms only havea bit period of 25 ps. Scope jitterof 1ps RMS can result in 6 to 9 psof peak-to-peak jitter, causingeye closure even if your signal isjitter-free.
