However, EVM is calculated from constellation points sampled at the center of symbol and often fails to represent what happens during symbol transitions. Symbol transitions or trajectories measured with sufficient analyzer bandwidth can reveal transmitter impairments such as IQ data skew, receiver channel skew, pattern dependent jitter, modulator chirp and more. Having an OMA system with a high bandwidth gives you the power to fully characterize and troubleshoot your transmitter. 32 GBaud QPSK - Modulator Chirp The chirp, or the instantaneous frequency variation over time, results in curvy transitions between symbols on the I vs. Q plot. An adequate bandwidth is necessary to resolve the transition with a high level of accuracy to be able to show the presence of chirp. Measurement with 20 GHz OMA Measurement with 36 GHz OMA Constellation Plot Vector Diagram Vector Diagram EVM = 8.3% EVM = 8.3% EVM = 6.3% 32 GBaud QPSK - IQSkew The IQ skew, or the time delay between RF drive signals of I and Q channels, introduce curvature to the inner transitions of the I vs Q plot. This is another example of signal characterization that can be achieved with a high bandwidth OMA system. Measurement with 20 GHz OMA Measurement with 36 GHz OMA Constellation Plot Vector Diagram Vector Diagram EVM = 7.2% EVM = 7.2% EVM = 5.5% 6 56 GBaud QPSK Source with 40 GHz Bandwidth Not only does the Coherent Solutions IQScope-RT with the Teledyne LeCroy LabMaster 10 Zi series of Oscilloscopes provide much greater characterization for 32 GBaud signals, it is the only commercial sys- tem capable of revealing a meaningful EVM at 56 GBaud signals and higher.
