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
AMHERST SYSTEMS ASSOCIATES, INC.
Copyright ©2005-2009 ASA Corp

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

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

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

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™

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."

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."

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."

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."

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."

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."

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."

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."

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."

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."

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."

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."

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."

• 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,

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."

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."

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."

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

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

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

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™

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."
