Analyzer is first to make key 40/100G net measurements

Created to perform physical-layer tests for components and signal paths of 40- and 100-Gbit/s single-wavelength transmission networks, the N4391A optical modulation analyzer (OMA) is said to be the first instrument of its kind. By performing in-depth, turn-key analysis of amplitude- and phase-modulated optical signals, it fills a gap in today’s measurement capabilities and lets engineers rapidly test their design concepts for fitting 100-Gbit/s transmissions into legacy 50-GHz ITU-T channel grids.

Based on the Infiniium Series 90000 oscilloscope, 89600 vector signal analysis software, and wide-bandwidth polarization-diverse coherent optical receiver technology, the OMA lets users develop new optical transmitters and receivers by analyzing phase as well as amplitude behavior of signals in two orthogonal polarization states. Previous test instruments could analyze only the amplitude of optical signals.

The analyzer has an receiver bandwidth >37 GHz electrical and 74 GHz optical, and a choice of 34 digital modulation formats and 20 customizable data-analysis tools. New types of optical analysis tools include a constellation plane display of the demodulated signal, and error vector magnitude analysis which displays the error compared to an ideal signal.
