Modules Overview
Optical/electrical modules
750-1650 nm
The 86105C has the widest coverage of data rates with optical
modulation bandwidth of 9 GHz and electrical bandwidth of
20GHz. The outstanding sensitivity (to –21 dBm) makes the
86105C ideal for a wide range of design and manufacturing
applications. Available filters cover all common data rates from
155 Mb/s ;through 11.3 Gb/s.
The 86105D is the premier solution for optical waveform
analysis for high-speed signals using short or long wavelength
technologies. The optical receiver bandwidth exceeds 20 GHz
and the electrical bandwidth exceeds 35 GHz, providing excellent
waveform fidelity. Switchable compliance filters are available at
all common rates from 8.5 to 14.025 Gb/s (16XFC). Sensitivity to
–12 dBm.
For high volume manufacturing or testing of parallel optical
systems, the 86115D can be used. The 86115D can be configured
with two or four optical ports in a single plug-in module. Each
port has specifications similar to the optical channel of the
86105D. (The 86115D does not have an electrical channel.) A
multiple optical channel plug-in can offer significant savings
compared to other configurations.
1000–1600 nm
40 GHz and greater optical and electrical channels:
The 86116C is the widest bandwidth optical module with more
than 65 GHz optical modulation bandwidth (1300 to 1620 nm) and
more than 80 GHz electrical bandwidth. Optical reference receiv-
ers for 25 or 40 Gb/s rates are available.
Dual electrical modules
86112A has two low-noise electrical channels with > 20 GHz of
bandwidth.
86117A has two electrical channels with up to 50 GHz of band-
width ideal for testing signals up to 20 Gb/s.
86118A has two electrical channels, each housed in a compact
remote sampling head, attached to the module with separate light
weight cables. With over 70 GHz of bandwidth, this module is
intended for very high bit rate applications where signal fidelity is
crucial.
The 86108A has two electrical channels with over 32 GHz (typi-
cally 35 GHz) of bandwidth. Clock recovery (similar to the 83496B)
and a precision timebase (similar to the 86107A) are integrated
into the module to provide the highest precision electrical wave-
form measurements. Residual jitter can be < 60 fs and trigger to
sample delay is effectively < 200 ps.
Clock recovery modules
Unlike real-time oscilloscopes, equivalent time sampling oscil-
loscopes like the 86100 require a timing reference or trigger that
is separate from the signal being observed. This is often achieved
with a clock signal that is synchronous to the signal under test.
Another approach is to derive a clock from the test signal with a
clock recovery module.
The 83496A and B provide the highest performance/flexibility
as they are capable of operation at any data rate from 50 Mb/s
to 13.5 Gb/s, (14.2 Gb/s for 83496B
1
) on single-ended anddif-
ferential electrical signals, single-mode (1250 to 1620nm) and
multimode (780 to 1330 nm) optical signals,with extremely low
residual jitter. PLL loop bandwidthis adjustable to provide optimal
jitter filtering accordingto industry test standards.
The 83496B has higher gain than the 83496A, allowing it to track
most spread-spectrum signals. The 86108A module has internal
clock recovery similar to the 83496B.
Time domain reflectometry (TDR)
The Infiniium DCA-J may also be used as a high accuracy TDR,
using the 54754A differential TDR module.
TDR/TDT analyses are commonly performed by signal-integrity
(SI) engineers during the design and validation of high-speed
serial links and components. TDR/TDT measurements are also
invaluable for maintaining consistent quality in printed circuit
board (PCB) and passive-component manufacturing.
The Agilent N1021B TDR 18 GHz differential TDR probe kit con-
nects printed circuit boards and other devices without connectors
to the 54754A differential TDR/TDT module in the 86100C
Infiniium DCA-J wideband oscilloscope mainframe. In conjunction
with these hardware components, engineers can use the optional
86100C-202 enhanced impedance and S-parameter software to
accurately characterize differential impedances in the time- and
frequency domains (for example, reflections and impedances
versus time or distance, or magnitude/phase/group delay of
S-parameters like SDD11/SDD21).
