6433F Lightwave Component Analyzer

6433F Lightwave Component Analyzer is a solution for testing the characteristics of high-speed electro-optical (E/O) devices, optoelectronic (O/E) devices, and optical-optical (O/O) devices. The modulation frequency range covers 10MHz ~ 43.5GHz and supports different frequencies. Range, frequency interval, intermediate frequency bandwidth settings, the minimum frequency resolution reaches 1Hz. 6433F Lightwave Component Analyzer adopts an integrated design solution. Through broadband hardware optimization design, it builds a network error model and uses the core calibration algorithm to achieve one-click broadband fast frequency sweep testing. It is mainly used for the core electro-optical components in modern high-speed optical transmission systems. Bandwidth and amplitude of devices (electro-optic modulators, directly modulated lasers, light emitting components), optoelectronic devices (PIN photodetectors, APD photodetectors, light receiving components), optical devices (optical passive devices such as fiber optic filters) Frequency response, phase-frequency response, group delay and other parameter tests.
