Accurate photodiode bias voltage is maintained internally. Magnitude and phase characterization of the O/E calibration module is obtained using Anritsu’s primary calibration lab standard characterized by NIST. Excellent converter stability ensures characteristics remain consistent during O/E DUT detector and receiver measurements. The MN4775A E/O converter includes a calibration module with a lithium niobate (LiNbO3) modulator stabilized by an automatic bias controller and a tunable or fixed-wavelength laser source. The MN4765B O/E calibration module is a photodiode reference standard detector that is thermally stabilized to minimize drift over temperature. The VectorStar ME7848A series ONA enables fast and accurate error-corrected transfer function, group delay, S-parameter, and optical power measurements in applications using E/O and O/E components.
For testing and characterizing devices like TOSA, ROSA, BOSA, and even on wafer SipH devices, an opto-electronic VNA that covers a microwave broadband frequency range is a must to have. The MA25300A module adds the next waveguide band and combines it with the Anritsu developed 0.8mm coaxial connector offering the world?۪s first broadband VNA operating beyond the limits of W band in a single sweep.Īll VectorStar ME7838 broadband systems include an RF VNA architecture using bridges instead of couplers to extend frequencies down to the RF bands (operational to 40 kHz) for near-DC analysis with excellent dynamic range.High-speed data rate testing involves photodetector and modulators that tackle a bandwidth of at least 110 GHz. The new ME7838D takes high performance broadband measurements to a new level with the addition of the Anritsu MA25300A mmWave module. The result is better calibration stability and better measurement stability with significantly longer time between calibrations for accurate measurements and improved productivity.
While other broadband systems continue to provide raw performance with negative directivity in critical frequency bands, the ME7838 series is the only broadband system with positive raw directivity in all bands. The VectorStar ME7838 Broadband series system provides high performance in a compact mmwave module with industry-best calibration stability.
