T
he DCA-J takes jitter analysis
to a new level of simplicity
and accuracy. Add to that the
scalability to any data rate that is
likely in the future, and you have the
ultimate in investment protection.
As device performance and system
requirements push jitter performance
to ever higher levels, it is sometimes
hard to distinguish between the
behavior of your device and the jitter
of your test equipment. That will never
be a problem with the DCA-J. The
instrument jitter in the standard mainframe is already very low. Combine
that with the 86107A precision timebase, and intrinsic jitter falls away
to less than 250 fs. DCA-J—see
what’s really going on.
Key enablers
• Jitter Measurements at any
rate, even beyond 40 Gb/s
• Jitter separation into
subcomponents:
• Total Jitter (TJ)
• Random Jitter (RJ)
• Deterministic Jitter (DJ)
• Inter-Symbol Interference (ISI)
• Duty Cycle Distortion (DCD)
• Periodic Jitter (PJ)
• Sub-Rate Jitter (SRJ)
• No need for a pattern trigger
• Stable, accurate measurements
• One button ease
• Wide bandwidth means lowest
intrinsic ISI/DDJ
• Lowest Intrinsic Jitter floor
means highest sensitivity RJ
measurements
• Support for all DCA plug-ins,
optical and electrical
• Limit tests provide quick pass-fail
jitter results
Displays that save you time
Sometimes you want to get in-depth
analysis of a difficult device performance issue. Sometimes you want
data views that are compatible with
other instruments so you can correlate multiple answers. And then,
there are times when you just want
to know whether your device meets
a standard.
The DCA-J handles all of these
situations by providing revealing
histograms and intuitive graphical
views, and by providing an easy and
simple table of jitter sub-components.
Its aim is to save you time.

As bit rates increase, jitter budgeting and
characterization of jitter performance present an
ever increasing challenge. In order to manage jitter
effectively, we need tools that can decompose the jitter into
the numerical and statistical forms that allow us to predict our performance
effectively and provide the insight necessary to solve problems quickly.
The new capability of the DCA-J provides irreplaceable visibility for
the challenges of jitter characterization of our world class
products. This new instrument is a major contribution
to our ability to manage jitter.
