2 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 2 SEEj™ The industry’s only RjDj Decomposition that… Runs identically on every real-time oscilloscope Is validated on more than 300,000 jitter cases Is specified for characteristic accuracy Is publicly and thoroughly documented for characteristic accuracy Circumvents vulnerabilities in other methods Works on both repetitive data and live traffic ** Provides less throughput degradation with increasing pattern length Displays convergence indicators and plots Stops on Rj, Dj or Tj divergence Finds errors that others cannot see ** Now one of a few.

3 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 3 One RjDj algorithm for all of the most popular scopes… Agilent LeCroyTektronix DSO 90000/80000/8000 Series 6xi/7zi/8zi series TDS70000 series TDS6154C/6124C DSO 6000 and MSO 6000 SeriesSDA seriesTDS6604/6804 DSO 3000 and MSO 3000 SeriesWaveMaster 8000 SeriesTDS/CSA7000 Series Agilent 5485x SeriesDDA3000/5000TDS5000 Series AT5483xLeCroy XStream familyTDS305x AT54846AWavePro 7000TDS694C AT54845AWavePro 950/960 TDS784/580 HP54720DWaveSurfer SeriesTDS794D LC584 Series

4 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 4 Data-jitter Algorithm Validation Engine (DAVE) Validation M1 Advanced™ v3.21 –SEEj™ functionality M1 Advanced™ v3.22 –“Gold Calibration” jitter test case results M1 Oscilloscope Tools™ v4 –Replaced gold calibration with a hybrid Rj/Pj “Total Calibration” and a DDJ/DCD/ISI gold cal –DAVE v1 Validation – 15,000 jitter cases –Accuracy better than 5%/0.002UI on Pj AND UI on Rj in the vast majority of cases M1 Oscilloscope Tools™ v4.04 –Added DCD and pattern length “Total Calibration” to the Rj/Pj “Total Calibration” –Pattern Length includes random data (i.e. live traffic) signals –DAVE v2 Validation - Jitter Space broken into ~300,000 parts –Add Decomposition Performance Explorer (DPE)™

5 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 5 SEEj™ Rj/Dj Decomposition Characteristic Accuracy DAVE v2 calibrates Rj, Pj & DCD “Jitter Space” is broken into 300,000 parts –Rj Amplitude –Pj Amplitude –Pj Frequency –DCD Amplitude –Pattern Length includes PRBS, random data (i.e. live traffic) and clock signals < 5%/0.002UI on Pj / < UI on Rj / < UI on DCD –For a vast majority of 300,000 jitter cases

8 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 8 SEEj™ Circumvents Other’s Vulnerabilities Slow sample rate Aliasing Sub-sampling Throughput on long patterns Can’t do “live traffic” (i.e. random data) signals Can’t see “time-variant” signals –Under-estimates jitter in presence of time variant jitter Rare event capture Limited debug capabilities

9 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 9 Live Traffic No limitation in M1 SEEj™ on live traffic Recommend using either convergence indicators or a Plot MAQ column of your RjDj statistics –Ensures that enough statistics are taken to get the precision that you specify to M1™ –Allows you to watch the convergence process, which can be insightful

10 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 10 RjDj Decomposition Throughput For 7 bit long repeating patterns –Almost the industry best For 9 bit long repeating patterns –Tied for the industry best For repeating patterns from 12 to 15 bits long –The industry best by a large margin For repeating patterns greater than 15 bits long –The most useable solution in the industry For Live Traffic –One of only a few solutions available in the industry

11 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 11 Convergence Indicators

12 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 12 Convergence Curves

13 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 13 Stop on Diverge

14 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 14 Finding and Tracing-to-root-cause Non-Stationary, Time-variant Jitter Runt pulses Bit Error bursting Crosstalk Glitches EMI Errors per billion Ground bounce Transient/flawed system behavior PLL resonance VSS/VCC susceptibility

15 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 15 BER Bursting Even precision sources can burst errors Today’s high-performance, highly integrated, mixed-signal designs can have this same problem BER Bursting is likely never seen without M1™

16 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 16 Digital System Debug that goes beyond RjDj Decomposition Event Triggering –Cycle-to-cycle, measurement-statistic limit comparison Multi-Acquisition –Analysis of every cycle in every acquisition Record/Playback –Multi-acquisition capture with post-capture “what-if” scenario analysis –On the scope or at your desktop PC

20 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 20 ASA Corp’s Rj/Dj Recommendations The idea of a ‘Best Method’ is invalid under MJSQ… To reiterate, under MJSQ, they are all acceptable. However, From the perspective of which method is “philosophically aligned” with what the spec actually wishes it could measure (edge jitter distribution)… »ASA recommends SEEj™ SEEj™ is the default, as well as the method selected when you press the “Best” button in M1™

22 A MHERST S YSTEMS A SSOCIATES, INC. Copyright © ASA Corp 22 Conclusion "I am comfortable saying that ASA has done more work and has provided more innovation in this space than every other competitor combined. We don't just look at a small handful of cases and then decide we're done. It's an ongoing quest for the very best possible solution. Calibration.. neural nets.. visualization tools.. wide-area validation.. NOBODY but ASA is giving you this kind of science or innovation. And NOBODY but ASA is giving you a way to get THE SAME method on all your scopes, no matter who made them. THAT is a genuine correlation strategy and it's only available from one place." - Mike Williams, President ASA Corp
