Atec Agilent-83491A-92A - Manual (Page 7)

When developing 40 Gb/s devices,
even a small amount of inherent
scope jitter can become significant
since 40 Gb/s waveforms only have a
bit period of 25 ps. Scope jitter of
1ps RMS can result in 6 to 9 ps of
peak-to-peak jitter, causing eye
closure even if your signal is jitter-
free. The Agilent 86100A and B have
been improved specifically for 40
Gb/s waveform analysis.

Accurate views of your
40 Gb/s waveforms
1 Unique methods and algorithm used in the precision
timebase module will be discussed upon receipt of U.S.
patent protection.
The same 40 GHz sinewave

and now with 86107A precision
timebase module (bottom).
The new 86107A precision timebase
reference module represents one of
the most significant improvements in
wide-bandwidth sampling oscillo-
scopes in over a decade.
1 Jitter
performance has been reduced by
almost an order of magnitude to 200
fs RMS. Oscilloscope jitter is virtu-
ally eliminated! The reduced jitter of
the 86107A precision timebase
module allows you to measure the
true jitter of your signal. The 86107A
requires a 10, 20 or 40 GHz electrical
reference clock that is synchronous
with the signal under test. Timebase
resolution has also been improved
from 10 ps/division to 2 fs/division,
a 5 times improvement.
Meeting your growing need
for more bandwidth
Today’s communication signals have
significant frequency content well
beyond an oscilloscope’s 3-dB band-
width. A high-bandwidth scope does
not alone guarantee an accurate
representation of your waveform.
Careful design of the scope’s
frequency response (both amplitude
and phase) minimizes distortion
such as overshoot and ringing.
The Agilent 86116A, 86116B and
86109B are plug-in modules that
include an integrated optical
receiver designed to provide the
optimum in bandwidth, sensitivity,
and waveform fidelity. The 86116B
extends the bandwidth of the
86100B Infiniium DCA to 80 GHz
electrical, 65 GHz optical in the
1550nm wavelength band. The
86116A covers the 1300nm and
1550nm wavelength bands with 63
GHz of electrical bandwidth and 53
GHz of optical bandwidth. The
86109B is an economical solution
with 50 GHz electrical and 40 GHz
optical bandwidth. You can build the
premier solution for 40 Gb/s wave-
form analysis around the 86100
mainframe that you already own.
