The result of several years of collaboration with the optical specialists at Coherent Solutions, the 70GHz Teledyne LeCroy IQS70 Coherent Optical Receiver pairs with the LabMaster 10-65Zi-A oscilloscope to provide a system bandwidth of 65 GHz, delivering an ideal solution for characterising leading-edge 56Gbaud communications systems and enabling detection up to 130GBaud.
For lower-rate applications, the 42GHz IQS42 Coherent Optical Receiver provides the test platform for up to 32Gbaud DP-16QAM or DP-QPSK when used with the 36GHz LabMaster 10-36Zi-A.
The instruments are complemented by Optical-LinQ, an intuitive and fully integrated software package for measurement and visualisation of optically modulated signals. It runs entirely within the user interface of the LabMaster 10Zi-A and it enables integrated control of both oscilloscope and coherent receiver.
Optical-LinQ provides fully automated control of the IQS receiver, phase recovery algorithms, and polarization demultiplexing, as well as an exhaustive number of modulation analysis displays and parameters.
In addition to a bandwidth of 70GHz, these Optical Modulation Analysis systems provide a dynamic calibration capability to enable the LabMaster 10 Zi-A real-time oscilloscope to be disconnected from the IQS Coherent Optical Receiver and used for other electrical validation and testing without requiring a factory re-calibration.
This enables dual use of the oscilloscope for serial-data eye diagrams and jitter, noise and crosstalk analysis on NRZ electrical tributaries using Teledyne LeCroy’s SDAIII-CompleteLinQ software package.
Teledyne LeCroy will demonstrate an OMA System consisting of an IQS70 receiver and a LabMaster 10-65Zi-A oscilloscope system at the ECOC Exhibition in Valencia (September 27-October 1).
