General Information
Key benefits
Agilent’s N4373C Lightwave Component Analyzer (LCA)
offers a modulation bandwidth of 67 GHz which makes it
the ideal choice to develop and characterize electro-optical
components, for the upcoming 40G/10GbE as defined in
IEEE802.3ba.
Accuracy
For these modern optical transmission systems with ad-
vanced modulation schemes it is key for the electro-optical
components to have very flat S21 transfer function in ampli-
tude and delay. This performance can be achieved only with
electro-optical S-parameter test as provided by the N4373C
LCA.
In addition fast, accurate, repeatable and traceable charac-
terization of these electro-optical components, like lasers,
modulators and detectors is required, to guarantee the per-
formance with respect to modulation bandwidth, jitter, gain,
and distortion.
By optimizing the electrical and the optical design of the
N4373C for lowest noise and ripple, the accuracy has been
improved by better than a factor of 2, compared to its pre-
decessor, the 86030A 50GHz LCA. This increased accuracy
improves the yield from tests performed with the N4373C by
narrowing margins needed to pass the tested devices.
This advanced design together with temperature-stabilized
transmitter and receiver ensures repeatable measurements
over hours without recalibration
‡ High absolute and relative accuracy measurements
improve the yield of development and production pro-
cesses. With the excellent accuracy and reproducibil-
ity, measurement results can be compared among test
locations world wide.
‡ High confidence and fast time-to-market with a NIST-
traceable turnkey solution.
‡ Significantly increased productivity using the fast and
easy measurement setup with an unique new calibra-
tion process leads to lower cost of test.
‡ External optical source input option to test at custom-
er selected wavelength.
‡ Common PNA and LCA user interface across all
N437xB/C LCA series.
‡ Identical LCA software and remote control across the
N437xB family simplifies integration.
Relative frequency response uncertainty:
± 0.8 dB @ 50 GHz (typ)
± 1.3 dB @ 65 GHz (typ)
Absolute frequency response uncertainty:
± 1.2 dB @ 50 GHz (typ)
± 1.8 dB @ 65 GHz (typ)
Noise floor:
-60(55) dB(A/W) for O/E measurements @ 50(65) GHz
-64(59) dB(W/A) for E/O measurements @ 50(65) GHz
Turn-key solution
The fully integrated “turn-key” N4373C helps reduce time
to market, compared to the time-consuming development of
a self-made setup. In addition you get a fully specified easy
transferable and reliable test instrument. With guaranteed
specifications Agilent takes the responsibility to provide
you with accurate and traceable test results that can only
be achieved in a turn key solution.
High productivity
The N4373C achieves fast measurements by including the
E8361C Performance Network Analyzer. A unique new cali-
bration concept significantly reduces setup time to a maxi-
mum of several minutes, depending on the selected mea-
surement parameters. This results in increased productivity
in R&D or on the manufacturing floor.
Using the advanced measurement capabilities of the net-
work analyzer, all S-parameter related characteristics of
www.DatahSehdeetv4icUe.cuonmder test, like responsivity and 3dB-cutoff fre-
quency, can be qualified with the new N4373C Lightwave
Component Analyzer from 10 MHz to 67 GHz.
Typical phase uncertainty:

Powerful remote control:
State of the art programming interface based on Microsoft
.NET or COM.

1 year warranty is standard for the N4373C Lightwave
Component Analyzer.
Extension to 3 or 5 years available on request.

The N4373C LCA is based on the new E8361C network ana-
lyzer with an identical and well known user interface across
all Agilent network analyzers.

Agilent N4373C Applications
Agilent N4373C Features
In digital photonic transmission systems, the performance
is ultimately determined by Bit Error Ratio Test (BERT). As
this parameter describes the performance of the whole sys-
tem, it is necessary to design and qualify subcomponents
like modulators and PIN detectors, which are analog by na-
ture, with different parameters that reflect their individual
performance.
These components significantly influence the overall perfor-
mance of the transmission system with the following pa-
rameters:
‡ 3dB bandwidth of the electro-optical transmission.
‡ Relative frequency response, quantifying the electro-
optical shape of the conversion.
‡ Absolute frequency response, relating to the conver-
sion efficiency of signals from the input to the output,
or indicating the gain of a receiver.
‡ Electrical reflection at the RF port.
‡ Group delay of the electro-optical transfer function.
Only a careful design of these electro-optical components
over a wide modulation signal bandwidth guarantees suc-
cessful operation in the transmission system.
Electro-optical components
The frequency response of detector diodes, modulators and
directly modulated lasers typically depends on various pa-
rameters, like bias voltages, optical input power, operating
current and ambient temperature. To determine the optimum
operating point of these devices, an LCA helps by making
a fast characterization of the electro-optic transfer function
while optimizing these operating conditions.
In manufacturing it is important to be able to monitor the
processes in regular time slots to keep up the throughput
and yield. In this case the LCA is the tool of choice to moni-
tor transmission characteristic and absolute responsivity of
the manufactured device.
Electrical components
Electrical components such as amplifiers, filters and trans-
mission lines are used in modern transmission systems and
require characterization to ensure optimal performance.
Typical measurements are bandwidth, insertion loss or gain,
impedance match and group delay.

Turnkey solution
In today’s highly competitive environment, short time-to-
market with high quality is essential for new products. In-
stead of developing a home-grown measurement solution,
which takes a lot of time and is limited in transferability and
support, a fully specified and supported solution helps to fo-
cus resources on faster development and on optimizing the
manufacturing process.
In the N4373C all optical and electrical components are
carefully selected and matched to each other to minimize
noise and ripple in the measurement traces. Together with
the temperature stabilized environment of the core com-
ponents, this improves the repeatability and the accuracy
of the overall system. Extended factory calibration data at
various optical power levels ensures accurate and reliable
measurements that can only be achieved with an integrated
solution like the N4373C.
Easy calibration
An LCA essentially measures the conversion relation be-
tween optical and electrical signals. This is why user cali-
bration of such systems can evolve into a time consuming
task. With the new calibration process implemented in the
N4373C, the tasks that have to be done by the user are re-
duced to one pure electrical calibration. The calibration with
an electrical calibration module is automated and needs only
minimal manual interaction.
Built-in performance verification
Sometimes it is necessary to make a quick verification of the
validity of the calibration and the performance of the system.
The N4373C’s unique calibration process allows the user to
perform a self-test without external reference devices. This
gives full confidence that the system performance is within
the user’s required uncertainty bands.
State-of-the-art remote control
Testing the frequency response of electro-optical compo-
nents under a wide range of parameters, which is often
necessary in qualification cycles, is very time consuming.
To support the user in minimizing the effort for perform-
ing this huge number of tests, all functions of the LCA can
be controlled remotely via LAN over the state-of-the-art
Microsoft .NET or COM interface. This interface is identical
for all LCA of the N437xB/C series.
Based on programming examples for VBA with Excel, Agi-
lent VEE and C++, it is very easy for every user to build ap-
plications for their requirements.
These examples cover applications like integration of com-
plete LCA measurement sequences.
