Enhanced Error Analysis Options

Product Overview

The Agilent 86130A BitAlyzer is
a complete 3.6 Gb/s error perfor­mance analyzer. It has many fea­tures, including advanced error
analysis, that will save you time.
In addition to the suite of standard
analysis features, described here are
two additional analysis options that
will give you greater insight.

Option 86130A-200:
Error Correction Coding
Analysis

Using the precise bit error locations
found by the 86130A BitAlyzer, map
these onto a user defined block code
error correction architecture such
as Reed Solomon. Check the con­straints imposed by the user defined
correction and see which errors
would have been corrected, and
which would not. All of the other
error analyses can then be used on
the post-corrected data, enabling
you to compare corrected and uncor­rected performances. Play “what-if”
games on your system without ever
having to build hardware.

Previous computer-based techniques
for correction simulation have often
assumed random noise models for
error distribution. You don’t need to
make guesses of how errors occur in
your channel, you can now measure
them precisely with your 86130A
BitAlyzer. If your channel suffers
from pattern sensitivity, or power
supply noise, then these are the error
locations that are presented to the
corrector design that you have cho­sen. Use this captured information to
stress your designs for accurate pre­dictions of their effectiveness in the
real world.

The 86130A supports two dimen­sions of error correction and three
dimensions of error interleaving
before the correction is applied.
It also supports erasure processing
where inner code failures can be
used to flag outer code erasure
thereby doubling your burst correc­tion ability. Statistics are also main­tained during analysis to give an
ongoing monitor of the corrector
effectiveness.

Monitor the performance of your emulated corrector with the
built-in statistics.

Create an image on the display that
represents the errors found on your
data channel. Select a divider for
the y-axis, such as a packet length
or an amount of time. For some
applications, this might have a
physical interpretation such as the
number of bits in a helical scan of a
video cassette recording system. In
such an example, you have a two
dimensional mapping based on
individual passes of the head across
the tape in columns on the display,
and all of the columns lined up next
to each other representing the num­ber of feet of tape.

In a similar way, examine long runs
of error results, and quickly zero-in
on areas that look interesting.
Leaving a test to run overnight with
a one second block size, for exam­ple, can be very revealing. With infi­nite panning and zooming, it is now

possible to examine clusters of
errors, and see structure such as
bursts or other groupings.

A picture really is worth a thou­sand words–or more importantly,
saved time.

See your errors in more revealing ways.
