Product Description
Flex SSG-EDC ,    is   a   Low    Cost    BERT     with    Electrical
Stressor Signal Generator   & 15G DSO in one instrument
for   Long   Reach Mode, Ultra   Long Haul and Submarine
applications,    intended    for     characterization    as   well
manufacturing. It generates the 3 LRM Stress conditions
(Post-cursor, Pre-cursor, Symmetric) to mimic worst-case
dispersion effects & Clean Eye, classified in the Standards
IEEE 802.3ae   10 GE   ,    IEEE 802.3aq     10 GBASE-LRM ,   for
generating      standard     stressed    signal    used   for EDC
(Electronic Dispersion Compensation) testing,    &    Long
Reach Multimode LAN, with BERT.

As   well   as   a   15G   Digital   Sampling   Oscilloscope   that
automatically   performs   accurate   eye-diagram   analysis
to characterize the quality of transmitters and receivers, implementing a statistical under-sampling technique with comprehensive     software     libraries     that     for     eye     measurements     and     jitter    analysis and processing of NRZ data.

EDC (Electronic Dispersion Compensation) Functionality
A multi-mode fiber (MMF) disperses the light from a laser, such that an optical pulse is split into multiple paths (“modes”) traveling at different speeds through the fiber, yielding multiple pulses that arrive at the receiver at different times. At 10Gbps data rates, the spread of these additional arrivals around the fundamental mode (the primary path carrying the most optical energy) can cause significant inter-symbol interference (ISI), preventing accurate recovery of the signal. Each transmitted symbol causes pre-cursor ISI to the preceding symbols, due to stray modes that travel faster than its fundamental mode.
The FLEX-SSG-EDC mimics the various stress conditions to ensure a DUT will work when deployed in a real network.

Applications
Mutli-Port system, High speed SerDes Testing and Characterization in system test applications or Line Card testing.
§ Electro-optical Transceiver Testing.
§ In-Situ testing of high port count systems.
§ Can be mounted on Automatic Test Equipment load boards, and fits into a Teradyne Ultra Flex Stiffener.

DSO Measurements
§ Mask Margin, Alternate Mask Margin rules available.
§ The mask margin (positive or negative) can be extracted for a defned number of points that fail, thus allowing for DUT quality assessment, control and binning.
§ The number of failed points for a region can be returned as well as the actual points that failed.
§ Eye opening, eye height and width, amplitude, Top, Base, Max, Min, Peak to Peak
§ Rise/ Fall Time, Single Edge measurement in pattern capture.
§ Total Edge Jitter, Statistics histograms, Histogram measurements and TIA meas.
§ Crossing point, crossing percentage.
§ Pre-emphasis positive and negative(amplitude and width).
§ Jitter Analysis
   oDeterministic jitter, Random Jitter
§ Advanced Pattern Measurements
   oEye measurements on specific bits of the pattern.
§ Frequency / Time measurements to sub-ppm.

The SSG-EDC with the DSO combination
§ Percentage of failing points vs the IEEE 3 LRM standard stress conditions mask.
§ User defined, Auto-detect & save Mask.
§ Rise and Fall Time calculation & Calibration.
