General Information

Key benefits

Agilent’s N4375B Lightwave Component Analyzer (LCA) is the

instrument of choice to test 10G Ethernet, FCx8, FCx10 and

FCx16 electro-optical components, with up to 20 or 26.5 GHz

modulation range.

Modern optical transmission systems require fast, accurate

and repeatable characterization of the core electro-optical

components, the transmitter, receiver, and their subcompo-

nents (lasers, modulators and detectors), to guarantee per-

formance with respect to modulation bandwidth, jitter, gain,

and distortion of the final transceiver.

For frequency dependent responsivity measurements

the N4375B is the successor of the industry standard

8703A/B LCAs.

With a completely new design of the optical test set and a

new RF-switched architecture, together with the latest PNA

family of network analyzers, the N4375B guarantees excel-

lent electro-optical measurement performance. In addition

a unique new calibration concept significantly reduces time

from powering up the LCA until the first calibrated measure-

ment can be made. This increases productivity in R&D and

on the manufacturing floor.

The fully integrated “turnkey” solution reduces time to mar-

ket, compared to the time-consuming development of a self-

made setup.

By optimizing the electrical and optical design of the N4375B

for lowest noise and ripple, the accuracy has been improved

by more than a factor of 3 and is now independent of the

electrical reflection coefficient of the device under test.

It’s the excellent accuracy that improves the yield from tests

performed with the N4375B, by narrowing margins needed

to pass the tested devices. NIST traceability ensures world-

wide comparability of test results.

The advanced optical design together with temperature-

stabilized transmitter and receiver ensures repeatable mea-

surements over days without recalibration.

Using the advanced measurement capabilities of the net-

work analyzer, all S-parameter related characteristics of the

device under test, like responsivity, ripple, group delay and

3dB-cutoff frequency, can be qualified with the new N4375B

Lightwave Component Analyzer from 10 MHz to 20 GHz.

‡ 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.

‡ More than 3 times faster than predecessor 8703A/B

series speeds up every test procedure

‡ New switched architecture of optical test set for long-

term reliability and stability of test results.

‡ Identical LCA software and remote control across the

N437xB family simplifies integration

The network analyzer

The N4375B comes in two basic versions. The economic line

is based on a PNA-L network-analyzer and is available as a

2 port system. The high end version is based on the new

PNA-X and offers true balanced measurements, extended

optical modulation index (OMI) and is available with 2 or

4 ports. Both versions have the same specifications up to 20

GHz. The PNA-X based LCA is calibrated up to 26.5 GHz.

Warranty:

1 year warranty is standard for N4375B Lightwave Compo-

nent Analyzer;

Extension to 3 years available.
