Agilent Technologies Extends Its Solutions for Complex Modulation Tests to 63 GHz
Highest Performance Real-time Optical Modulation Analyzer
Accelerates Development of Next-Generation High-Speed Networks

SANTA CLARA, Calif., Sept. 12, 2012.
Agilent Technologies Inc. announced the industry’s first real-time optical modulation analyzer with a bandwidth of 63 GHz.
The new instrument allows researchers to characterize the latest coherent receivers and ultrafast transmitters with a sample
rate of 160 GSa/s at 63 GHz electrical bandwidth.
The system is capable of real-time sampling on four channels, each with 33 GHz bandwidth, in a single oscilloscope.
The N4391A real-time optical modulation analyzer offers comprehensive tools to analyze and quantify the integrity of
a vector-modulated signal for error-vector magnitude, quadrature error and other impairments. The N4391A offers measurement
and compensation of the link’s in-channel chromatic dispersion and first-order polarization mode dispersion by analyzing the
received signals, granting engineers deep insight into the root cause of constellation distortions beyond 32 Gbaud.
For the greatest flexibility, users can process the raw digitized data coming from the N4391A’s optical coherent receiver
using the Microsoft .NET® framework and include the results as a user-provided library. For flexible data analysis, customers
can include their algorithms in the burst-mode processing system of the N4391A. The N4391A can handle any number of algorithms
in a user-selectable sequence.
“At Agilent we are committed to helping our customers speed up the development of next-generation coherent components and
subsystems,” said Joachim Peerlings, marketing manager of Agilent’s Digital Photonic Test business. “Whether they use the
latest generation of the N4391A optical modulation analyzer in research, or they use the portable, compact N4392A real-time
modulation analyzer in manufacturing and system integration, our customers can rely on consistent measurements throughout
the entire design cycle of their products.”
At ECOC 2012, Agilent will demonstrate the Infiniium 90000 Q-Series oscilloscope with industry-leading bandwidth up to 63 GHz,
the industry’s highest four-channel bandwidth with 33 GHz in a single frame, and the industry’s lowest noise and jitter
An additional demonstration will show how to perform real-time modulation analysis of a 100-Gb/s dual-polarization QPSK
signal using the compact, portable and affordable N4392A, an instrument suitable for 100-Gb/s R&D, manufacturing and system
