    Industry Leading Bandwidth and Sample Rate

    70 GHz Coherent Optical Receiver bandwidth provides up to 130 GBaud symbol rate analysis when used with the 65 GHz LabMaster 10-65 Zi acquisition modules.

    Modular Scalable Architecture
    Upgradable oscilloscope bandwidth (20 GHz – 65 GHz and channel count (4 in a single unit and up to 80 with additional acquisition modules). Choose the functionality you need now and upgrade later.

    Seamless Multi-Module Configuration
    ChannelSync architecture utilizes a single 10 GHz distributed clock to precisely align all acquisition modules for lowest inter-channel jitter and the highest confidence in results.

    Unmatched Software Integration
    Optical LINQ, the OMA Signal Analysis software, runs on the LabMaster 10 Zi and is fully integrated into the DSO software giving you a seamless, intuitive interface.

    Smart and Dynamic Calibration
    The IQScope-RT provides optimized signal fidelity and adaptive self-calibration allowing the receiver to be disconnected and reconnected without factory calibration.


    The IQScope-RT Coherent Optical Receiver brings optical modulation analysis to the Teledyne LeCroy LabMaster 10 Zi oscilloscope. As a calibrated reference receiver, the IQScope-RT performs heterodyne detection on both orthogonal polarization components of the optical field.
    Coherent Optical Receiver



    LabMaster 10 Zi is the world’s highest bandwidth (65 GHz) real time oscilloscope. The modular design allows more channels with better performance, and permits simple and easy upgrades.


    • World’s Highest Performing Real-Time Oscilloscope – 65 GHz bandwidth, (5.2 ps risetime 20 – 80%), 160 GS/s sample rate, up to 80 channels, up to 1024 Mpts of analysis memory
    • Modular – start with four channels and grow your system over time. Spread out your investment as funds permit
    • Wide bandwidth upgrade range (25 – 65 GHz) provides investment protection
    • ChannelSync™ architecture utilizes a 10 GHz distributed clock for precise alignment of all acquisition systems
    • Single trigger circuit for all modules eliminates additive trigger jitter that occurs with 10 MHz clocking and trigger synchronization of multiple conventional oscilloscopes
    • Simple – connect and acquire – Teledyne LeCroy has done the hard work for you
    • 325 MB/s data transfer rate from the LabMaster to a separate PC with Teledyne LeCroy Serial Interface Bus (LSIB) option

    Unmatched Software Performance

    Optical-LINQ software

    IQScope-RT comes with the Optical-LINQ software for analysis of optically modulated signals. The software is integrated into the oscilloscope application, controls the IQScope-RT receiver and performs all necessary calibrations. Users can select a wide variety of analysis views and parametric measurements to gain a complete understanding of their optical signal path.

    Unrivalled Software Integration

    The OMA functions and controls are fully integrated in the LabMaster oscilloscope software. You can apply any of LabMaster’s extensive signal diagnosis tool kits directly on the OMA signals. LabMaster’s user-friendly interface also allows intuitive layout of visual and numerical analysis outputs which can be customized to your liking.
