Agilent unveils wide-band complex modulation analyzer

Agilent Technologies Inc. (NYSE: A) has introduced what it claims is 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 of electrical bandwidth.

Agilent Technologies Inc. (NYSE: A) has introduced what it claims is 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 of electrical bandwidth.

The system is capable of real-time sampling on four channels, each with 33-GHz bandwidth, in a single oscilloscope. Agilent will demonstrate the instrument at ECOC (Booth 712), on September 17—19, in Amsterdam.

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 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 measurement floor, the company asserts (see "Agilent ups bandwidth ante with Infiniium 90000 Q-Series real-time oscilloscopes").

An additional demonstration will show how to perform real-time modulation analysis of a 100-Gbps DP-QPSK signal using the compact, portable and affordable N4392A, an instrument suitable for 100-Gbps R&D, manufacturing and system integration applications.

The N4391A optical modulation analyzer is available immediately in various configurations up to 33-GHz bandwidth, based on a single Infiniium real-time oscilloscope. [UPDATE] Configurations up to 63-GHz bandwidth are scheduled for release by the end of this year.

The N4392A compact optical modulation analyzer is available now, with prices starting at $151,000.
