New Enhancements
Reference receiver for
39-43 Gb/s systems
In 2002 Agilent was the first to
provide an oscilloscope with the low
intrinsic jitter necessary to accurately
view 40 Gb/s signals. The 86100 in
conjunction with the 86107A
Precision Timebase became the
de facto standard for 40 Gb/s R&D.
As such systems are now beginning
to make their way from the lab to
production; the new 86116C performs
as a reference receiver that allows
designers, manufacturers and their
customers to reliably verify component
and system specifications.
Variable loop bandwidth clock recovery
suited for spread-spectrum clocking
The 83496B multi-rate optical/
electrical clock recovery module
performs clock extraction for waveform analysis with continuous,
unbanded tuning from 50 Mb/s to
13.5 Gb/s, ultra-low residual jitter
and Golden PLL (phase locked loop)
operation. It tolerates large periodic
jitter from Spread Spectrum Clocking
(SSC), and can tune its loop
bandwidth between 15 kHz and
10 MHz. Internally the recovered
clock signal is a subrate (1:8) and
routed to the mainframe. The front
panel provides the recovered clock
at a user-selectable rate (1:1
1
, 1:2, 1:4,
1:8, 1:16).
Solving jitter problems through
phase/frequency domain analysis
The 83496B can be used as a phase
noise analysis system. Phase noise
based measurements can be achieved
on both clock and data signals at
rates from 25 MHz to 6.75 GHz and
50 Mb/s to 13.5 Gb/s respectively.
The examples above show frequency
resolved jitter for the clock and
data lines of a PCI-Express system,
indicating how the jitter from the
reference clock is translated to the
data line. With high dynamic range,
low level random jitter spectra can
be observed at the same time as large
spread spectrum clocking jitter and
harmonics. The ability to observe
specific jitter tones as well as the broad
noise spectra provides important
insights into the root causes of jitter.
The measurement range is from
300 Hz to 20 MHz. Since jitter is
obtained in an analog technique,
results are obtained in a matter of
seconds. Virtual PLL responses can
be built in to emulate system level
performance.

up to 13.5 Gb/s.

Get Deep Insights To Address Root Causes
T
he 86100C Infiniium DCA-J can now decompose amplitude
interference (Option 300) and timing jitter (Option 200) so that
designers can accurately see interference and jitter contributions,
and get a full picture to get to the root cause.
Relative intensity noise (RIN)
RIN is a random
noise contribution caused by
the spontaneous
emission background of lasers. Excessive RIN can limit the power budget in
an optical system. Option 300 measures RIN either based on the “1” power
level or on OMA. Combined with automatic normalization to 1 Hz, the
DCA-J’s results compare easily and directly with those recommended by
standards (e.g., IEEE 802.3ae).
Signal/modulation impairments
Large separation between ‘one’ and
‘zero’ levels is essential for error-free
communications. This type of signal
strength is commonly determined
with standard 86100C automatic
measurements like “eye-amplitude” or
OMA (optical modulation amplitude).
Option 300 provides an advanced
technique for determining signal
amplitude. The user can isolate specific bit sequences to compose a signal
amplitude measurement. The impact of various data patterns can be
examined. Standards based OMA test, usually requiring a square wave
pattern, can now be derived from virtually any data pattern. Option 300
also separates out the various mechanisms that cause eye amplitude
closure similar to timing closure (jitter) examined using option 200.

he ultimate
flexible tool—
the 86100C digital
communications analyzer
with advanced jitter
analysis (DCA-J). Four
instruments in one – a
digital communications
analyzer with automated
eye measurements; a full-
function time domain reflectometer
(TDR) for impedance analysis; a full
function oscilloscope with bandwidth in excess of 80 GHz; an innovative and accurate jitter analyzer for
electrical and optical signals.
With the ability to accept plug-in
modules that you already own from
the 83480A/54750A and 86100A/B,
the DCA-J also protects your
investment.
