![]() ![]() ![]() The VectorStar VNA can be easily switched between electrical and opto-electronic measurements. ![]() In contrast to turnkey solutions, the same VectorStar VNA model can be used at multiple wavelengths, so purchasing additional VNAs is not necessary. The ME7848A-100 series can be upgraded to a 200 series by including the appropriate MN4775A E/O converter. The ME7848A ONA can be easily modified to a different wavelength by adding the appropriate MN4775A E/O converter and MN4765B O/E calibration detector. The built-in application menus guide the user through set-up and full 12-term, de-embedded calibration required for simplified E/O and O/E de-embedding measurements, resulting in stable and repeatable measurements of opto-electronic devices. 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. High-speed data rate testing involves photodetector and modulators that tackle a bandwidth of at least 110 GHz. ![]()
