Coherent Lightwave Signal Analyzer

From the Leader in Performance Mixed Signal Oscilloscopes

The OM4245 Coherent Optical Modulation Analyzer provides the ultimate flexibility in your system configuration by being tightly integrated with the DP070000SX Series 70 GHz real-time oscilloscopes and the DSA8300 Series 70 GHz equivalent-time oscilloscope.
The OM4245 uses coherent detection to acquire fiber signals carrying up to 80 GBaud, then analyzes both modulation and source properties using the power of optical industry tested DSP. It presents a rich library of results and graphical plots with the ease of use offered by a dedicated graphical user interface. Dynamic and feature-rich MATLAB integration provides the ultimate in analysis system customization and extensibility. 
Key Features
Unparalleled Flexibility
  • Coherent Lightwave Signal Analyzer Architecture Compatible with both Real-time and Equivalent-time Oscilloscopes*1
  • Complete Coherent Signal Analysis System for Polarization-multiplexed QPSK, Offset QPSK, QAM, Differential BPSK/QPSK, and Other Advanced Modulation Formats
  • Displays Constellation Diagrams, Phase Eye Diagrams, Q-factor, Q-plot, Spectral Plots, Poincaré Sphere, Signal vs. Time, Laser Phase Characteristics, BER, with Additional Plots and Analyses Available through the MATLAB Interface
  • Measures Polarization Mode Dispersion (PMD) of Arbitrary Order with Most Polarization Multiplexed Signals
Precise Optical Receiver
  • Precise Coherent Receiver Hardware provides Minimal Variation over Temperature and Time for a High Degree of Accuracy and High-stability, Polarization-diverse, Optical Field Detection
