Agilent extends solutions for complex modulation tests to 63 GHz

Agilent Technologies has announced the industry’s first real-time optical modulation analyzer with a bandwidth of 63 GHz. The new instrument will allow researchers to characterise 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 analyser offers comprehensive tools to analyse and quantify the integrity of a vector-modulated signal for error-vector magnitude, quadrature error and other impairments. It offers measurement and compensation of the link’s in-channel chromatic dispersion and first-order polarisation mode dispersion by analysing the received signals, granting engineers deep insight into the root cause of constellation distortions beyond 32 Gbaud.

Users can process the raw digitised 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.

“Agilent is committed to 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 analyser in research, or they use the portable, compact N4392A real-time modulation analyser in manufacturing and system integration, our customers can rely on consistent measurements throughout the entire design cycle of their products.”
