OM1. 10. 6 Optical Modulation Analysis Software, Datasheet The OM1. Optical Modulation Analysis (OMA) software provides an ideal platform for research and testing of coherent optical systems. It is a complete software package for acquiring, demodulating, analyzing, and visualizing complex modulated systems from an easy- to- use interface. The software performs all calibration and processing functions to enable real- time burst- mode constellation diagram display, eye- diagram display, Poincar. Advanced users can take advantage of the provided MATLAB signal analysis source code and modify the signal processing algorithms while still taking advantage of the rich user interface for acquisition, signal visualization, and numerical measurements. Key features Complete coherent signal analysis system for polarization- multiplexed QPSK, QAM, differential BPSK/QPSK, and other advanced modulation formats Displays constellation diagrams, phase eye diagrams, Q- factor, Q- plot, spectral plots, Poincar.

The OMA software consists of a number of major building blocks. At the heart of the software is a complete library of analysis algorithms. These algorithms have not been re- purposed from the wireless communications world: they are specifically designed for coherent optical analysis, executed in a customer- supplied MATLAB installation. The OM1. 10. 6 software also has a complete applications programmatic interface (API) to the application measurement and analysis algorithms, letting you perform detailed analysis of complex modulated optical signals without requiring any knowledge of MATLAB, analysis algorithms, or software programming. You can take measurements solely through the OMA software user interface, you can use the programmatic interface to and from MATLAB for customized processing, or you can do both by using the OMA software as a visualization and measurement framework around which you build your own custom processing. OMA user interface The OMA software has displays for all of the standard coherent optical visualizations such as eye diagrams, constellation diagrams, Poincar. The software also provides a complete measurement suite to numerically report key measurements. Constellation measurements include elongation, real and imaginary bias, magnitude, phase angle, EVM, and others. Eye diagram measurements include many key time domain metrics such as eye height, overshoot, undershoot, risetime, falltime, skew, crossing point, and so on. All numerical measurements also provide statistics to enable data gathering over longer periods of time. Symbols can also be colored to a key indicating prior state.

The OMA software lets you easily configure and display your measurements and also provides software control for third- party applications using WCF or . NET communication. The software can also be controlled from MATLAB or Lab. VIEW. The following image shows a QAM measurement setup. The plots can be moved, docked, or resized within the application work space or into separate windows on the desktop. You can display or close plots to show just the information you need.

The Measurements tab- a summary of all measurements in one place. Make measurements faster. The OMA software is designed to collect data from the oscilloscope and move it into the MATLAB workspace with extreme speed to provide the maximum data refresh rate. The data is then processed in MATLAB to extract and display the resulting measurements. Take control with tight MATLAB integration. Since 1. 00% of the data processing occurs in MATLAB, test engineers can easily probe into the processing to understand each step along the way. R& D labs can also take advantage of the tight MATLAB integration by writing their own MATLAB algorithms for new techniques under development. Use the optimum algorithm. Don’t worry about which algorithm to use. When you select a signal type in the OMA software (for example, PM- QPSK), the application applies the optimal algorithm for that signal type to the acquired data. Each signal type has a specially designed signal processing approach optimized for that signal. This means that you get results right away. Don’t get stymied by laser phase noise. Signal processing algorithms designed for electrical wireless signals don’t always work well with the much noisier sources used for complex optical modulation signals. Our robust signal processing methods tolerate enough phase noise to make it possible to test signals that would traditionally be measured by differential or direct detection such as DQPSK. Find the right BER Q- plots are a great way to get a handle on your data signal quality. Numerous BER measurements vs. Plotting BER vs. Gaussian noise will produce a straight line on the Q- plot. The optimum decision threshold and extrapolated BER are also calculated. This gives you two BER values: the actual counted errors divided by the number of bits counted, as well as the extrapolated BER for use when the BER is too low to measure quickly. Q- plot. Constellation diagrams. Once the laser phase and frequency fluctuations are removed, the resulting electric field can be plotted in the complex plane. When only the values at the symbol centers are plotted, this is called a Constellation Diagram. When continuous traces are also shown in the complex plane, this is often called a Phase Diagram. Since the continuous traces can be turned on or off, we refer to both as the Constellation Diagram. The scatter of the symbol points indicates how close the modulation is to ideal. The symbol points spread out due to additive noise, transmitter eye closure, or fiber impairments. The scatter can be measured by symbol standard deviation, error vector magnitude, or mask violations. Constellation diagram. Constellation measurements. Measurements made on constellation diagrams are available on the “fly- out” panel associated with each graphic window. The measurements available for constellations are described below. Color features. The Color Grade feature provides an infinite persistence plot where the frequency of occurrence of a point on the plot is indicated by its color. This mode helps reveal patterns not readily apparent in monochrome. Note that the lower constellation groups of the example below have higher EVM than the top groups. In most cases this indicates that the quadrature modulator bias was too far toward the positive rail. This is not evident from the crossing points which are approximately correct. In this case an improperly biased modulator is concealing an improperly biased driver amp. Color Grade Constellation. Color Grade with fine traces. Color Key Constellation Points is a special feature that works when not in Color Grade. In this case the symbol color is determined by the value of the previous symbol. If the prior symbol was in Quadrant 1 (upper right) then the current symbol is colored Yellow. If the prior symbol was in Quadrant 2 (upper left) then the current symbol is colored Magenta. If the prior symbol was in Quadrant 3 (lower left) then the current symbol is colored Light Blue (Cyan). If the prior symbol was in Quadrant 4 (lower right) then the current symbol is colored Solid Blue. This helps reveal pattern dependence. The folowing figure shows that pattern dependence is to blame for the poor EVM on the other groups. Digital Multi- Track Recorders & Players. B& H # TADA6. MFR # DA- 6. 40. 0Top Highlights.
